50ml - Our category defining, hardest-hitting retinol is buffered to perfection to deliver maximum change without irritation. At 8000 IUs, this level is for skin that is experiencing significant signs of aging—loss of firmness to deep wrinkles. The retinol is encapsulated into a formula that includes Niacinamide and vitamins D and F, which actively repairs collagen and elastin, and accelerates the cell renewal at every layer. With consistent nightly use, you’ll see a noticeable softening and firming of texture and improved coloration.

No side effects. Goes on easy. Feels great on skin. My sun spots are noticeably fading and my skin makes me happy.

Big 5 star

I switched to another retinal due to price. I quickly found out sometimes you do indeed get what you pay for. Back again to Dr. Koo

Totally love this Retinol

I've tried other Retinol products in the past and none have come close to being this good. You won't get an oily residue or sticky feeling. It leaves my skin feeling tighter and smoother. Absolutely love it.
