Retinol is a form of Vitamin A and proven to help with anti-aging.
It promotes collagen production, increases new cell turnoever, and protects your skin as an antioxidant.
Retinol boosts collagen production and increases cell turnover. This makes retinol effective in removing wrinkles, fading dark spots, and reducing the appearance of pores.
Retinol is less effective when exposed to sun. Be sure to look for appropriate packaging to keep your retinol potent.
Using retinol and retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.
We recommend speaking with a medical professional about using this ingredient during pregnancy.
Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.

Definitely high-dose retinol!
This is a powerful retinol serum that is no joke. I tried easing into it by going every other night, then moved to every night. I ended up with signs of a damaged skin barrier (redness) on my chin. I'm going to lay off this on my chin for a couple weeks, then try again, but stick to every other night. I like that I'm getting a strong dose of an excellent skincare ingredient, but I need to take care not to overdo it.
