  • Vitamin C

    Ascorbic acid is the most active and best researched form of vitamin C, which is why we gave it a starring role in our formulation. This proven antioxidant will protect your skin from the environmental stressors that lead to skin ageing, while boosting brightness.

  • Glutathione

    This innovative pairing allows pure ascorbic acid to be delivered deeper into the skin, while preserving all of its benefits in the process. As a result, this is a high performance vitamin C serum that is also suitable for sensitive skin.

Wait for the serum to fully absorb and follow with a moisturizer to lock all the good stuff in.

05 - The glow-up.


What is the strength of vitamin C in this serum, and what type of vitamin C is it ?


We use a new skin delivery technology that delivers the Vitamin C deeper into the skin while preventing oxidation. This means we only have to use 0,5% ascorbic acid, a low percentage that is more effective than a regular 20% Vitamin C formula.


Do your products have microplastics?


Our products do not contain microplastics.


Is it useful to use several serums at once?


Yes, you can achieve better targeted results depending on your skin goals by using several serums at once.

Magic serum!

The bakuchiol serum is seriously magical. Somebody recommended it to me, and said she wasn't usually a skincare person, but that this really worked. I am usually skeptical of such claims, but when I tried the serum, my skin immediately felt smoother and my wrinkles soften. Also, oddly, this little area of hyperpigmentation under my eyes (that give me the appearance of bags) started fading. I bought three bottles for my friends, because I really think this serum is different than the ones I have tried before.

Gentle, smooth, sophisticated

After two weeks of use there is already a slight effect. The serums feel gentle on the skin. The scent is pure and smooth. Everyday a sophisticated start. The only thing I am missing is a moisturizer which matches perfectly with the serums.
