#3388860 My Tca Peel Diary - 18% On Skin Type Iv (Middle Eastern)

I hope you know what you are doing. As far as I know, TCA is not supposed to be used on darker skin. Especially at these relatively high concentrations. You are running a significant risk of getting hyperpigmentation and/or hypopigmentation. You are also at a greater risk for hypertrophic scarring.

#3388078 Why Is My Retin-A/tretinoin Not Working?

The longer you use antibiotics like minocycline and clindamycin, the less effective they will become. This is because bacterial resistance will develop.


It is a big deal if you are consistently missing retinoid applications. Make sure it is being applied every night. I find I can miss one night every so often but any more than that and things become problematic. 


0.025% tretinoin cream (Retin-A Micro?) is pretty mild. This is why you did not experience much irritation when first trying it. I would switch to gel (you will get better absorption) and move up to 0.04% at the very least. If you don't get improvement within a month immediately move up to a 0.1% concentration, and perhaps also switch to tazarotene.


A lot of the time variations in the state of your skin are due to variations in your diet. Make sure your monitor your intake of animal milk products and high-glycemic load foods and see if there is any correlation between such intake and the state of your skin.

#3183664 Hydrocortisone Cream

It is simple to tell if your red marks are erythema or pigmentation. Erythema disappears on blanching (finger pressure), while pigmentation and pupura (bleeding under the sin) do not. Also, erythema tends to be bright red or pink, while pigmentation tends to be much darker (dark red or dark brown).

In my experience erythema disappears quickly. I mean, sure, it can definitely last much longer than several days, but I think that would be uncommon. You can usually see red skin resulting from erythema noticeably lighten back to normal day-by-day. If you have had the marks for several weeks and have seen little/no improvement, then I think it is much more likely that what you have is pigmentation.

But maybe it is erythema. Watch this derm talk about erythema resulting from acne lesions and how to treat it. This video is excellent.

#3183375 Hydrocortisone Cream

The "red marks" which follow the healing of a lesion tend to be erythema, PIH, or a combination of both. These are all results of the inflammatory response. I'd guess that, technically, reducing inflammation during the healing process of the lesion would reduce the resulting erythema and PIH... but I think hydrocortisone is far too weak to have any real effect. You'd need a potent cortisone injection directly into the lesion to have any real effect (which doctors will commonly do with cysts).

As for after the lesion has healed... hydrocortisone might help with the erythema (which would naturally recede in a couple days anyways), as it tends to contract the capillaries, but it wouldn't do anything for the PIH.

In any case, hydrocortisone - even at an over-the-counter concentration (0.5% or 1%) - can't be used for the long-term (not really longer than a week, I'd say), because it can cause a huge host of side effects, such as skin atrophy and permanent erythema.
