I like this product. It is gentle on your face. It has .5 retinol, which most experts tout as the best thing for tightening skin and reducing wrinkles. So far so good. Highly recommend. Read more

I love this retinol serum however be aware it's concentration is higher than others so a little goes a long way. I never had any skin irritation or any issues when applying it in my regular skincare routine. However it's advised not to use retinol every day or when scrubbing your face. It's very lightweight and your skin is able to absorb it nicely so it won't leave your face oily. I noticed that if you don't keep it in the fridge that the color of the serum may change to a darker color due to oxidation so best to keep it in a regular fridge. Read more

I have tried so many retinol products (as well as other anti-aging and skin smoothing products) and this is the best overall. I have age 50+ mature, dry, sensitive skin. A lot of retinol products end up burning my eyes or flaking my skin, they have a weird texture, smell bad, or just don’t work. This is like liquid gold. It’s in oil form. I put it on about an hour before I go to bed so it has a chance to absorb. I eliminated all other serums at night. Now I just use this after I cleanse my face. It’s all I need. My sagging chin has lifted and my skin is much more even and smooth. I didn’t have a lot of wrinkles for my age, but it’s smoothed the crow’s feet around my eyes. I’m on my 3rd bottle. I saw a difference after only about a few weeks. It’s amazing stuff! Read more

Ive been using it for a month now, i dont think it works the way i expect it to effect on my face.. the liquid are sticky on face, have to wait like 45min or longer to be fully absorb which is a little annoying... might change brand for retinol after i finish this bottle.. Read more
