Love this serum!
Upon recommendation from my dermatologist I have been using this for the last few weeks and absolutely love it. A little goes a long way, the application is smooth and my skin feels and looks great!

Surprisingly gentle for such a robust retinol product
I was recently advised to try a higher dosage retinol treatment. I was initially nervous as my first experience (with a 4% retinol serum) took a bit of getting used to as it caused some minor redness and dryness in the early days. I have been using Serum 16 nightly for over a week and my skin is loving it! It goes on very smoothly, smells subtly delicious and is surprisingly gentle at 16%. Highly recommended.

Serum 16
Easy to use no redness occured after use. Was able to use it every evening. Will need longer to see any difference to my skin.
