Ingredients
  • Retinol

    Otherwise known as vitamin A, this is one of the most studied and effective ingredients in skincare. Our .35% concentration prevents and treats signs of premature ageing, reduces blemishes, and balances tone and texture for firm, vibrant skin.

  • Squalane

    A natural fatty acid derived from olives, best known for its moisturizing and skin-replenishing properties, without clogging pores. Squalane is an ideal oil for blemish-prone skin and a perfect compliment to retinol, as they both have the ability to reduce signs of skin aging.

squalane (emollient), coco-caprylate/caprate ( emollient ), retinyl palmitate (skin restoring), bisabolol (skin soothing), tocopherol (antioxidant)

How to apply
How

Press the dropper and release 2-3 drops in the palm of your hand, on your finger tips or directly on a cleansed face and neck.

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

Ask us anything

We're here to help and demystify everything about
The youth tonic.

Can I use this serum also for the eye area?

Yes, this serum is especially developed to be safe to use under the eyes. We have seen impressive results in crow's feet improvement in our clinical trials.

Is retinol safe with sun exposure?

Yes, perfectly safe. As with all active ingredients that stimulate cell turnover: your skin has a layer of dead skin cells less than usual. For some people this means a temporary increase in skin sensitivity when it comes to sun exposure. In the case of retinol it is temporary as your skin actually gets stronger after using retinol for a while. We always advice to use a daily SPF in any case if you want to achieve the goals related to retinol.

When should I apply retinol?

After the build up, you can use it every evening.
