Retinol Alart!!!

If you think your skin needs it, use it immediately. The sooner the better. I suggest, do it slowly to introduce to the skin. so that the skin is not shocked. For example, initial use starts with 3 times a week to see how your skin reacts. If, you are sure your skin is ready, the intensity of its use is increased to 2 times a week. and so on, until your skin is ready to use retinol every day. Don't forget to wear sunscreen every day. And pay attention to the use of other active ingredients.

What are the skin concerns you want to treat? I’ve used retinol in my early twenties as a mild way to help prevent acne (as well as preventing aging) but I know it’s not for everyone. Happy to offer different actives suggestions for what results you’re looking for though 😊

I think this too young, 21 be better if you preparing strength skin barrier. but if you want retinol use low % and start slowly, started with toner and than serums

after 25 is ideal

of course! but only once or twice a day!
