I've been using Retin-A(Tretinoin) for about 3 years now. So happy 😊 I found 'GETRET365' ❤️ and got retin-a a way cheaper. It is hands down the most effective anti-aging, anti-dark spot, anti-whatever skin flaw you may have. It's also the only thing that has actually helped with my acne. People comment on my skin daily, and have for the past 3 years since I started using it.
