MasterCell is an epidermal stem cell boosting day serum.

It is the best topical product for sensitive and discoloured skin as it reduces inflammation and increases cell turnover for faster recovery and strengthened barrier function.

Use mornings before GlowScreen SPF50 for best results.

Daily use delivers long term results.

Our encapsulation and carrier technologies are unique to MasterCell, delivering a high concentration of Niacinamide, Lactic Acid, Zinc and Glucosamine that visibly improves acne prone and ageing skin after 30 days.

MasterCell promotes skin renewal by increasing epidermal cell turnover

Reduces signs of sun damage and ageing, including pigmentation (Kimball, 2010)

Reduces blotchiness and increases elasticity (Bissett, 2006)

Formulated by Doctors from the University of Oxford & Universität Münster


Distribute approximately 1 whole pipette fillings evenly over the face and décolleté in the morning on clean, dry skin, allowing to dry.

As our MasterCell Serum contains concentrated amounts of B3, pure glycerin and lactic acid, delivering intense nourishment without a heavy or tacky feel.
We recommend to follow up with GlowScreen SPF50 to lock in hydration and shield skin from environmental stressors, blue light and UV rays.
MasterCell should be used as a first step in your morning skincare routine, and should be used daily for best results.

Store in a cool, dry place.
Do not store in the fridge.
The bottle contains 30ml/1 fl. oz.

Dr. Lars Ruether is KLARSKIN's in-house physician. Dr Ruether is a Biochemistry and Molecular Biology specialist and the scientific mind behind our products and why they work so well for sensitive and problem prone skin.

He included the encapsulation and carrier system technology that our serums contain to ensure a steady, even release of raw materials. This is why our serum works so well to target both acne, pigmentation and aging.

Dr Ruether has formulated this serum specifically for acne prone complexions, especially those that are starting to see their first lines and wrinkles whilst also experiencing acne. Formulated to be used daily, our MasterCell renews skin’s epidermal cell turnover over time, helping clear and strengthening the moisture barrier.
