I have very dry skin and I want to improve the texture of the kin on my arm. I tried 25% but it did nothing. When I say my arm, I mean my whole arm length.
If it is texture you are looking for, it is better to apply a body lotion with lactic acid (Lac-hydrin) or urea (Carmol-10). Applying TCA really won't cause hydration or change your texture caused by dryness. Applying TCA at 50% is very risky also as it can lead to scarring given the high concentration.
