Ok so wow i have been seeing this a lot and i want to make one thing clear once and for all. Do not do TCA Peel on your stretch marks. That is like shooting your self on your wounded leg. TCA peel on it own can cause stretch marks when it is not done right. Stretch marks are thinned skin and TCA Peel would only strip the skin of what is left and make it worse. The best case scenario when you do a TCA peel on your stretch mark is that nothing happens and the worst case is that things can get way worse. Ways to Minimize Stretch Marks. Moisturize the skin a lot. Avoid doing strenuous activities that may affect the area. Don't be aggressive when washing the area. Eat healthy food that can help you reduce weight. In short stay away from any kind of peels including lactic acid, glycolic acid, salicyclic acid and tretinoin. Don't use any chemical peels or AHA peels on your stretch marks.
