What makes it different?
At the heart of the formula is Yon-Ka's Retinol-Like Active Duo.
Encapsulated biomimetic microalgae
A biotechnology-derived active that delivers a structural analogue of retinoic acid, helping stimulate cellular activity and support skin renewal.
Mastic tree active
A plant-derived active designed to support and enhance the skin's retinoid mechanisms, complementing the action of the microalgae.
Together, they form Yon-Ka's exclusive [RE]NEW Technology — a retinol-inspired approach to visible skin renewal without compromising on comfort.

Who is it for?
We'd recommend Yon-Ka Retinol-Like Bi-Serum if your concerns include:
It's particularly interesting if you've wanted to introduce a retinol-inspired product but prefer an alternative to traditional retinol, or your skin tends to be sensitive.
How to use
Shake well before use to combine the two phases.
Apply to clean skin on the face and neck morning and/or evening, either alone or underneath your usual moisturiser.
Gently press into the skin and take a moment to enjoy Yon-Ka's signature aromatic experience.
Touch & Glow recommends
If you've always associated visible skin renewal with traditional retinol, this is an exciting alternative.
Yon-Ka has approached the same conversation differently: combining two naturally derived retinol-like actives to target wrinkles, texture, pores and firmness while prioritising skin comfort.
It's a brilliant choice for anyone who wants to focus on healthy ageing and visible skin renewal without making their routine feel more aggressive or complicated.
