My personal favourite

Very nice texture and skin looks refreshed. Applying once a day and already stocked up for a new piece. Followed instructions on how to apply and never had any side effects. Recommended!

Best retinol

5 stars out of a maximum of 5

Started with this one the retinal 1 and loved it. Now moved up to the retinal 3 strength which is also wonderful. Really improved skin texture and small bumbs for me!

Amazing 🤩

5 stars out of a maximum of 5

Absolutely amazing! My pimples just kept getting from bad to worse. The thing is I never had this problem before. My skin has always been pretty good to me. Occasionally I will get 1 or 2 dots during period. But this time it is really bad for me. Did a research on this particular brand and decided to try. (Wonderful wonderful reviews) im sold. I could see the difference in my skin within a week or so. Absolutely 💯 amazing. I just bought no 3. Yay!!! Highly recommend to everybody 😍

SKIN IS GLOWING

5 stars out of a maximum of 5

Perfect retinal for beginners! I haven’t had any irritation/ skin dryness and I have very sensitive skin. Been using this product for a month now every 3 days and now going to use other night in evenings. My skin is glowing and clearer. Will be using number 1 twice before progressing to number 3, just to build up tolerance.  Remember to use SPF in the mornings when using this product.

Amazing retinal for beginners ! Noticed zero flakiness, dryness or redness. Been using for 3 weeks now and using 3 times a week in evenings. My skin looks so much clearer and brighter already. Looking forward to progressing to number 3

Gentle retinol

5 stars out of a maximum of 5

I haven't been using this serum for super long but so far I am very happy with it. It isn't sticky or anything to apply and goes on really well. Really impressed so far.

I had high hopes

3 stars out of a maximum of 5

I had high hopes but this was a let down. I have acne prone skin and acne marks, I used this religiously but my skin is worse in some aspects - I went through the dreadful purging period which was over 6 weeks and after several months, my pores are worse ( I stopped using my BHA and the retinol couldn’t do what my BHA did) - regular acne and the marks are still there - lots of little red post acne marks around my face and redder cheeks  Retinol/ retinaldehydes are raved about so much that I am in two minds, either skipping this or upping the strength
