Radiance Booster – 10% Vitamin C

115.00 USD

Visible results for your skin

Swissline’s effective formulas awaken the senses, giving you the relaxation and revitalization you've been longing for.

How to use

Radiance Booster can be applied am and/or pm as needed, mixed in the palm of the hand with the Recovery Serum to maximize results, or directly in your usual cream for a boost. During the first week, we advise limiting the use to the pm, so as to allow skin to better adapt. 2-3 drops are enough, more can be used if needed. The use of an adapted UV protection during the day is imperative to better protect the skin (and the vitamin C in the formula!).

STAY-C® 50

Ascorbyl Sodium Phosphate is a more stable form of vitamin C, registered as a quasi-drug in Japan. Recognized as an antioxidant, it illuminates the complexion and reduces the signs of age. Radiance Booster contains also pure L-ascorbic acid – the most active, yet least stable form of vitamin C – together with an ascorbic acid salt form, which greatly contributes to better stability in the very high concentration.

STAY-C® 50 is a registered brand of DSM Nutritional Products AG (DSM Nutritional Products SA /DSM Nutritional Products Ltd), Switzerland. Stated in vivo studies carried out by DSM with a panel of 40 volunteers aged 35-45 years old.

It's quite gentle for my sensitive skin

I'll sometimes get irritation or stinging to my skin whenever I apply a vitamin C. But I don't get any of that with this one! I can see it slowly working to bring back some radiance I need without the irritation.

Marie @ayylienss

an effective beauty routine

It’s not sticky, sinks in quickly, and smells like citrus.
