Maximizes the pros whilst minimizing the cons of incorporating vitamins into your skincare!

To optimize the benefits, pure vitamins or derivatives are carefully selected to amplify the effects and enhance the delivery of active ingredients into the skin.

Synergistic components are also added to minimize the side effects associated with using highly concentrated vitamins.



Firming serum enriched with stabilized vitamin A derivative


0.5% of stabilized Retinyl palmitate (vitamin A derivative) works to refine uneven skin texture, treat signs of sun damage, wrinkles, and surface imperfections such as hyperpigmentation and scarring.



Minimized stimulation with Calendula officinalis extract


Contains Calendula officinalis extract to soothe and calm the skin, to minimize the possibility of stimulation.

Retinyl palmitate and Calendula officinalis extract work together to restore the skin, leaving the complexion flawless in the most gentle way possible.



Great starter serum for new retinoid users


Emulsion type, light-weight texture that absorbs quickly into the skin.

Suitable for first-time retinol users looking to refine skin texture, diminish the appearance of fine lines and wrinkles for firmer, younger-looking skin.
