Favorite Retinol

I love this retinol. I have very sensitive skin but don't get too much irritation with this. I've been using it a few months and it's cleared my the cystic acne I was struggling with on my cheeks. The smell isn't great but bearable

Great Formula

First of all, this smells exactly like goji berry to me, which is welcome although a surprise based on the ingredients list. I really like this product although realistically I cannot offer a miracle that it erased wrinkles in the 2 months I've been using it - I view this product as a long term investment. The oil based formula makes it gentle on the skin and the dropper allows you to dispense the proper (tiny!) amount you need for your face. I avoid the eye area as I am already using bakuchiol eye cream but I have experienced no dryness or significant irritation from using this product, although I have fairly tolerant skin towards actives.

The most gentle retinol

I find this retinol very gentle with my skin .I use it almost every day and there’s have been not any irritation problem .I see a little difference on my smile lines,I guess I just have to wait a little longer.

Great value for the size

Can't wait to try this out, I was previously using the innisfree retinol cica serum, and the retinol amount is way too little to see a huge difference, so I thought I would mix a little bit of this in to increase the concentration. Hope it works!


i don’t know how i even lived without it before. I love putting it on in the evening - you only use 1-2 drops (it really covers your entire face) and dab it in your skin. I love how it feels and feels like my skin is smoother than before

first time!

it’s my first ever retinol and I must say it has improved the appearance of my skin. though I don’t use it as regularly as I shouid the results are positive.
