There's more info on this here in that resveraterol thread I keep telling people to visit. Do it. It's good. Link straight to a post on sphingosine http://www.acne.org/...80#entry3235002

 

 

>Yeah, that's a great thread..I've been applying grapeseed oil topically (light amounts, before bed) to my face, neck/upper chest. By morning it's fully absorbed and my face is not oily. I've seen some improvement, but I'll post back after a month or so to confirm.Going to get some organic yogurt (as plain as I can find at Publix) for face masks and try that as well.PS, my grapeseed oil is sold unrefrigerated, I've seen you mention yours must be kept cold?</p>

 

Unless you buy it in small quantities that you use up quickly, you should store it in the fridge. Regardless, it should be stored in the dark. Try to get the best quality you can and a sign that they care about quality is that it will come in a dark bottle. I buy a brand from California that also makes a very good olive oil (based on everything I know about quality olive oil) so I'm hoping they also make a quality grapeseed and safflower oil. We discussed the olive oil scam and what to look for in a good olive oil in a thread a few weeks ago: http://www.acne.org/...ly#entry3234933

Circadian cycle affects linoleic acid metabolism

During darkness, high levels of melatonin released by the pineal gland block the ability of tumors to take up linoleic acid and convert it to 13-HODE (a molecule called 13-hydroxyoctadecadienoic acid). While exposed to light, however, melatonin levels are extremely low, and tumors are no longer protected by melatonin from the tumor-stimulating action of linoleic acid. In other words, exposure to artificial light when it is naturally dark, scrambles the molecular clocks in our brains. Light presented during the night will immediately turn off melatonin production and thus support tumor growth."

Does this mean that melatonin supplementation may prevent cancer? I think 100% of us are exposed to artificial light at night....

You should research that. For me, it's just one more way as natural as possible circadian cycle is good for you. An unnatural one is bad. And a possible reason people's acne gets better on vacation, in sunlight, etc. Because they are outdoors in bright light.

It's also possible that UV light stimulates the conversion of beta carotene to retinoids in our skin. And polymorphism of a gene/enzyme involved in this conversion has been identified in acne prone skin.

In the list of benefits in my first post is a reduction in hyper pigmentation. I have had a red splotch on my face for months, possibly since last July. It occasionally would get more inflamed and red then fade a bit. But it was always something that needed extra conceal or. I just noticed thatbit has faded to the point that I haven't made an effort to conceal it in a week or so. I don't know if it is just inhibiting the pigment or if it is healing whatever it is.

Well. Degussa has a nasty history. They made pesticides and a chemical used in the gas chambers in the Holocaust.

This is from a company that sells products with something called Inca Inchi Oil.

Linoleic acid is a necessary element of sebum. Sebaceous glands release sebum to supply lubrication of follicles and surrounding skin. Linoleic acid and alpha-linoleic acids are 'essential fatty acids' required by the body. You may be more familiar with these bio-chemicals as Omega-3 and -6 oil.

Studies have discovered links that propose that Trans fats may break down the body's own supply of linoleic and alpha-linoleic acids. This is why acne breakouts are more likely to appear in people that have a deficiency in Omega-3 and Omega-6 oils.

The appearance of acne can be due to sebum being produced with oleic acids which can cause irritation to the skin. It has been suggested that oleic acid sebum is more desiccant, stiffer and more prone to create blackheads, whiteheads and to shape follicular plugs which lead to blemish infections.

It is known that Omega-3 decreases inflammation and that Omega-6 promotes inflammation. A lack of these oils encourages the development of skin conditions while a correct balance helps to maintain and promote well being.

 

They don't cite a source with this article, but I've posted something about trans fats breaking down linoleic acid before. And we've had people that noticed they break out when they consume trans fat.

would hemp seed oil be just as good as grapeseed oil? i've seen people who recommend it highly above the other oils. if so, what should i look for when buying hemp oil? i have many blocked pores, many of which eventually get inflamed and turn into spots, so i think the oil method would work for me

Since hemp seed has omega 3 EFAs as well, it might be a better, natural replacement for the Allerderm for dogs which has a mix of EFAs. Whether those omega 3 EFAs are beneficial to us/acne, I don't know. It's supposed to be completely noncomodegenic whereas the grapeseed and safflower might be mildly comodegenic. But I haven't had any problem with them, and hemp seed is more expensive.

is there anyway for the body to normalize sebum quality by itself? anyway to correct this linoleic deficiency from the inside through some calculated diet/supplements?

^ Good question.

My sebum quality is very waxy and therefore very sticky.

is there anyway for the body to normalize sebum quality by itself? anyway to correct this linoleic deficiency from the inside through some calculated diet/supplements?

 

Well, since one theory is that the relative deficiency is due to the linoleic acid being diluted by excess sebum, anything that reduces excess sebum would help:

Foods that improve the PPAR receptor balance (which is what accutane does) such as resveraterol, sesamin (as in sesame seed), chlorophyll, fish oil/omega 3s, and linoleic acid. Also stable blood sugar/insulin.

http://www.acne.org/...n/#entry3234944

Anything that supports thyroid function helps as thyroid hormone affects the composition of lipids:

http://www.acne.org/...n/#entry3235072

Avoiding trans fats as studies have found that it accelerates the break down of linoleic and alpha linoleic acids

http://www.acne.org/...n/#entry3235308

Gut flora also apparently affect lipid metabolism/profile in tissues. I don't know how, but I have an abstract to a study/report that says so:

http://www.acne.org/...20#entry3242187

(The next topics about enzymes and possible mutations are harder to understand and simplify, and the points at which I start feeling to tired to continue and quit trying to get to the bottom of it all. But I suspect the root cause of our deficiency is here. Enzymes are how your genes do their jobs, btw.)

Retinoids also affect lipids in sebum:

A phenotype mutation in the enzyme stearoyl-CoA desaturase 1 (SCD1 has been found in problem skin.

http://www.acne.org/...n/#entry3235335 Coenzyme A/B5 are supplements that may improve this function.

Beta carotene and UV rays (sunlight) might stimulate retinoid production in the skin. I started gathering info on that here: http://www.acne.org/...00#entry3233046 And in the next post. The CYP26AI enzyme is involved in retinoic acid in the skin. I think it breaks it down, therefore we want to inhibit it. also affects vitamin D synthesis.

Melatonin - So cancer studies have found that 'high levels of melatonin released by the pineal gland block the ability of tumors to take up linoleic acid and convert it to 13-HODE (a molecule called 13-hydroxyoctadecadienoic acid). While exposed to light, however, melatonin levels are extremely low, and tumors are no longer protected by melatonin from the tumor-stimulating action of linoleic acid' Yeah, so that's about cancer cells. But I'd say that as natural as possible circadian cycle will improve your lipid profile and linoleic acid deficiency in sebaceous glands. Maybe the ability of your sebacious glands to take up linoleic acid.

Avoid Aspirin and other NSAIDS. And steroids like cortisone:

the non-steroidal anti-inflammatory drugs (NSAIDs; antirheumatic drugs) like aspirin interfere with the complicated fatty acid metabolism via enzyme inhibition it is recommended to take into account any possible side effects of medication.

By means of the enzyme phospholipase A₂, arachidonic acid is released from phospholipids. Prescriptions containing cortisone act as enzyme inhibitors and thus will prevent the formation of arachidonic acid metabolites which support inflammations. Any inflammatory processes in the skin can thus be treated immediately and also very effectively. The other side of the coin is, however, that the skin will develop deficiencies in the supply of other important fatty acids, a fact that will consequently result in atrophic skin.

(And see, I've decided that my dog scratches and chews himself to occupy himself whenever I leave him home alone. Like the dog version of cutting. So I'd nearly decided to take him to the vet for a cortisone shot to stop all the itching and hopefully by the time it wears off, the habit will be broken. But doing so will make his deficiency worse at the same time. )

------------------------

Also note that peroxidated squalene has been implicated as a cause of the inflammation that is at the root of malformed cells that don't differentiate properly. http://www.acne.org/...0#entry3242146 And olive oil is high in squalene. http://www.acne.org/...20#entry3242176

-----------------------------------------------

Apparently 3 genes have been identified that affect the lipid profile in skin:

Changes in at least 3 groups of genes encoding structural proteins, epidermal proteases and protease inhibitors predispose to a defective epidermal barrier and increase the risk of developing atopic dermatitis. http://www.acne.org/...20#entry3238844

And if we do have mutations in our genes/enzymes that govern these processes, then I'd say a topical application of linoleic acid is important.

I've been using grapeseed oil on my face once a day for about two weeks now and I gotta say there is a noticeable improvement. At the very least, it's really nice to rinse my face with. But I do notice improvements in my skin texture, and it helps reduce the redness.

Could using BP have contribute to a linoleic acid deficiency in sebum?

I don't know. I've only found info on steroids and NSAIDS inhibiting enzymes involved in lipid metabolism. You'd have to see if it hinders the processes any. I've seen a lot of info on peroxidated lipids, especially squalene as being a major culprit in acne as a source of inflammation.

And yeah, one of the many good things linoleic acid in sebum does is inhibit melatonin. I think it's evening out my skin tone too. Pretty quickly. And I'd been doing other things that are supposed to help with that. Niacinimide for example.

Hm, I think in some ways, BP might have done things to my skin to make it more acne prone. Just a hunch.

The vitamin E in grapeseed might also be having a beneficial effect on my skin. I think doing things to my skin that make it less acne prone is also a pretty good approach in addition to a healthy lifestyle. Nuking my face with BP was only a temporary solution and only served to age my skin along with bad health habits.

hey guys since seeing this post i bought some grapeseed oil and was washing my face with it every night.

Basically the first week my skin was super smooth, loved it. for about 1-2 and a half weeks my face was the clearest it has been in about a year (not kidding) to the point i forgot about my acne i was actually incredibly happy, I thought this was my solution. Kept using the grapeseed oil, nearly finished my big bottle and sadly my face broke out during my period (usually im clearest on my period) and since then my face has been a pizza face again. last night it was so horrible worst its been in a long time. my skin also doesnt feel as smooth as it did when i first started using the grapeseed.

sigh! totally had SO much faith in it. Does anyone know why maybe the effect wore off? The effect of my face was far too noticable so i know it was the grapeseed that altered my face to clear it up, to the point i didnt even have red marks..but yeah its all back again. mostly around my forehead and mouth/chin (i guess the typical hormonal).

I'm going to the health store soon and will buy a different brand. do you think maybe my grapeseed oil went off? didnt smell off though.

but yeah still following this post im still intrigued

Could you have been overdoing it? It might take more time.

Also, I'm not sure everything lumped together as acne develops with the same pathways. Normal acne is a slow process of malformed cells that don't exfoliate properly without sticking together, clogs a pore far below the surface, then takes weeks to come to the surface. Or so they tell us. Whereas, acne from a food intolerance can appear in a day or so. And acne triggered by monthly hormone changes doesn't take weeks either.

do you mean washing my face with it every night would help? the odd thing is for 2 weeks it definitely seemed a miracle, I've been using it for over a month though. perhaps it wasnt the grapeseed at all but i havnt been clear in a long time and i think that was the closest i have been to clear.. i understand over doing anything is bad but would washing every night be bad? if anything wouldn't that be a good thing i wonder?

also you mentioned how long pimples form, how long do hormonal pimples take to form because my face can easily go from lots of pimples to none in literally a day, for example 2 nights ago I had a lot of tiny white heads on my cheeks..got depressed and just went to bed still back to square one. in the morning most were gone and my usual pimples just remained. so i guess sleep helps greatly but yeah i guess im a little mixed up but my acne definitely gets worse after my period and often before..even though last month was an odd month where i got more acne during my period for the first time ever (usually im clearest when on my period) so very confused right now but then again i never did have a clue whats going on with my face ..

what acne are you suggesting linoleic acid helps? I thought it was the general skin and 'fixing it' to the state where acne of all sorts is prevented from forming type thing?

No I wouldn't think daily cleansing is too much, but that could vary from person to person.

Linoleic acid helps mammalian skin function, period. And it helps true acne as well as other skin problems caused by impaired skin and sebum function such as psoriasis, excema, keratosis pilares, and issues animals get such as hyper sensitivities to fleas and mites. I pretty clearly stated what it does for your skin in the first post and then posted the many studies where i found that information. Deficiencies cause skin problems. And people and animals with skin problems have been found to be deficient in linoleic acid in their sebum.

However, a pimple that appears in a day as an allergic response can't possibly be the result of the normal acne formation. Which is why I don't think it is true acne. It's more like a hive, that the body can make appear and disappear. Only the acne doesnt just disappear like a hive does. It has to heal. And since acne that comes and goes with the menstual cycle also appears within a much shorter time than the several weeks they tell us it takes acne to form, I suspect that maybe it isn't true acne either. But I can't tell you how long it takes to form or why.

sorry yes i did read everything was just getting confused as I thought either way acne was acne if its a pimple on your face than I figured it was acne rather than it being true, im not really sure what true means i guess the type that takes weeks to form. Which doesnt make too much sense for my kind because it definitely of how it appears around my period.

im sorry if you've answered me this before but even so with acne that relates around a period, i realize its a certain hormone doing that but why does that cause pimples to form? i guess put more simply what does too much of that hormone trigger?

that could be a broad question you dont have to answer that haha.

I suppose I put hope in linoleic acid for hormonal acne, i will keep using it though.

back to th drawing board I expect :/

honest to god dont even know what to do ive tried everything and i dont even say that with an ignorant manner, i really have tried every possible approach.

hmph.

i will buy a hopeful better quality grapeseed oil when i get the chance

Topical application is still only a part of things you have can do to control acne.. but diet control is a better way of controlling acne.. and THE diet that reverses the acne prone nature into a strong stable system that takes care of the person automatically is.. well.. the cure right?

I'd just like to add here that.. in a thread about mainly topical application, the other 2 or 3 things you have to do to help fight acne should be at least pointed out somewhere, forgive meh if it has already.

what's the idea or thinking of why this grapeseed oil and safflower oil will work?

-how does it prevent acne from forming, how does it disrupt the acne forming system?

-what does it do to existing pimples? how does it affect/alter the sebum in formed acne?

-does it help normalize sebum? does it liquidify waxy thick sebum into.. waterry thin sebum?

I guess I'm a disbeliever, but a few kinds of oils applied topically is supposed to do all that? What if it doesn't work? I know controlling acne and pimples is one thing.. but actually changing the acne-prone nature of the skin (the thick abnormal sebum).. that's a tough ass game to win.

I think linoleic acids role in sebum and skin is pretty clearly spelled out in the first post and title.

you are truly amazing alternativista!! I feel this lack of linoleic acid is the cause of my skin to be in a constant state of clogged pores, dry skin, seborrheic dermatitis, food intolerances. I have changed my diet almost 2 years ago and my skin is worse now than ever. I loved reading all the info about being deficient in linoleic acid and therefore sebum is more sticky, this is exactly my problem in my chin area and I have not been able to change. Ive applied grapeseed oil a year ago as my moisturizer and it only added to my problems. I take good supplements and eat well but have a problem with oils topically for some reason. I did ALCAT testing and was found intolerant to many foods (which i've avoided for 3 months and no improvment) and many types of fish were a problem so Im not sure how to increase my lipid level or change my sebum. I am recently trying cod liver oil but its only been a few days. Do you think applying grapeseed oil to say my forehead where i dont have clogs or ingesting it would help? I cant change my skin and its killing me after all these years...Also is grapeseed extract supplments the same as grapeseed oil?
