Dan, I love your moisturizer

24 April 2009 - 05:22 PM

Seriously, first moisturizer out of all the years i've used moisturizers on my face that I actually like.  Doesn't make me look oily and doesn't break me out.  Also, I love that it has no petroleum or mineral oil.  If you ever discontinue it, I think I will cry and have no choice but to gather pickiters and protest.

Thank you thumbsup.gif

pH of the Acne.org moisturizer?

Hey Dan, I'm about 2 seconds away from ordering your moisturizer (all I have to do is click "place order"!), but before I do so, I was just wondering what the pH of the  moisturizer is. smile.gif  Thanks!

I'm dying to try Dan's AHA, but........

Now, I'm absolutely dying to try Dan's AHA. So much that I actually opened up a checkings account and ordered a debit card just so I could order it. saywhat.gif

I have heard nothing but raving reviews and I think it would be a great product to try to fight minor breakouts and even out my skin tone.

HOWEVER, are there any dangers to over exfoliation with AHA's?

Lately I've been reading on the internet something called the "Hayflick Limit."

http://www.senescence.info/cells.html


"The Hayflick limit is the number of times a cell will divide before it stops due to the telomere reaching a critical length"
(taken from wikipedia)

I've read that AHA's and BHA's may make the skin hit the hayflick limit sooner than it should.  For example, this website.. bottom paragraph-

QUOTE
The dangers of excessive skin exfoliation:  Less wrinkles today could mean more wrinkles tomorrow   Main benefits of alpha hydroxy acids come from their ability to exfoliate skin. Removal of the outermost layer of the skin stimulates the cells in lower layers to grow and divide, causing the skin to thicken and thus diminishing visible signs of aging. The more you exfoliate the more cell divisions will occur in the lower skin layers. There is one problem though. Normal human cells cannot divide indefinitely. Fibroblasts (a key type of cells in the skin) would divide about fifty times and then enter a so-called stage of senescence. This limit of about fifty cell divisions is called the Hayflick limit (after its discoverer, Dr. Leonard Hayflick). This is a state in which the cell is sluggish, inefficient, unresponsive to various signals from the body and unable to divide. Skin with many senescent cells is usually fragile blotchy and easily wrinkled.  

Exfoliation remains a valuable cosmetic tool but if you overuse it, your skin may "hit the Hayflick limit" earlier than it should. In recent years, researchers have discovered the molecular mechanism of the Hayflick limit. (It has to do with the areas at the tips of chromosomes called telomeres). Medical technologies to eliminate the Hayflick limit may appear in a reasonably near future. These technologies are likely to work only for those cells whose Hayflick limit has not yet been reached.  

Today's good news is that Hayflick limit does not appear to be carved in stone. Research indicates that very simple measures available today may help extend it by as much as 50 percent. (Further details are included in the  Skin Rejuvenation Infopack ).

I'm hoping these so called "dangers" are just scare tactics.  The last thing I would want is for AHA's to make me AGE in the end (I've started a hardcore antiaging routine already, god forbid! tongue.gif)   I know Paula Begoun SORTA debunked the theory.  Plus, tests were only done via petri dish rather than in vivo.  Still though, all these websites saying "stop using glycolic acid or you'll age more due to the Hayflick Limit!" are scaring the shit out of me lol.

Thoughts?  If someone can debunk this, I'll start using glycolic acid immedietly and for the rest of my life.
