Retin A is a derivative of Vitamin A. It is a very popular treatment used for acne, scars and wrinkles. Retin A helps skin cells to turn over more rapidly and also helps exfoliate your skin to reduce the build up of dead skin cells. That is probably why it works well for those with acne. There are studies that show Retin A can help make collagen, reduce fine lines and increase epidermal thickness which would be helpful for those who are concerned with wrinkles. But this ingredient does come with side effects. Some of which are dryness, itching, redness, peeling or flaking. Some users have reported a slight stinging when they apply Retin A. Another side effect of Retin A is that it can make your skin more sensitive to the sun. I’m guessing its because Retin A thins the outer layers of your skin (the effect of exfoliating). Many would suggest that you should avoid sun exposure and tanning beds and to use sunscreen. Retin A is also not recommended for women who are pregnant. The first part of Retin A sure sounds good…but the benefits of it just doesn’t seem to out weight the side effects - to me anyway. I’m sure women who love Retin A would disagree. I have used it before and I thought it did more harm than good. When I applied it, it feels like it burns. After a while, my skin feels so irritated and red. On top of that, my skin was flaking too. I went back to see my dermatologist and she suggested that I should use a product with a lower percentage of Retin A in it. I used it for a total of about a month. I have not seen any improvements in my skin at all. I thought that it was worse off than before I started using it. But some dermatologist says that it takes time to work and if you are patient with it, you will see the benefits. But the idea of burning my skin and making it irritated and flaky and red is just not right to me. What are you thought on Retin A?
