Clarins introduces a breakthrough bi-phase serum designed for all skin types, offering a double dose of potent actives: Stabilized Vitamin C and Glycolic Acid (AHA). This innovative formula merges these powerful ingredients to deliver a supercharged glow. The serum is intended for application on a clean face and neck, both in the morning and/or evening. It promises three glow-boosting actions in one product.

The Science Behind the Glow: A Bi-Phase Formula
For the first time, Clarins’ groundbreaking science has successfully combined two active molecules that were previously incompatible: Stabilized Vitamin C and Glycolic Acid (AHA). This unique combination is encapsulated in an ultimate radiance-boosting serum. To ensure the efficacy of each ingredient, a bi-phase formula is employed, keeping the oil-soluble Vitamin C and water-soluble AHA suspended in two separate layers until the product is first used. A single shake of the bottle merges them into a distinctive pink micro-pearl texture that is lightweight, quick-absorbing, and hydrating.
The serum maintains this opalescent texture, and a quick shake before each application guarantees that the ingredients remain evenly dispersed, ensuring optimal potency with every use.
Three Clinically Proven Actions for Maximum Radiance
This transformative serum is clinically proven to enhance skin's glow through three key actions:
- Exfoliation and Smoothing: It effectively exfoliates the skin, smoothing its texture for a refined feel.
- Brightening and Evening Tone: The serum works to brighten the complexion and even out skin tone, reducing the appearance of discoloration.
- Pore Refinement: It refines the appearance of pores, contributing to a smoother and more uniform skin surface.
The results are reported as instant, with continued improvement observed after 28 days of consistent use.

Key Ingredients and Their Benefits
The Clarins Vitamin C serum is powered by a carefully selected blend of ingredients, each contributing to its potent effects:
Stabilized Vitamin C
This ingredient is crucial for boosting the skin's glow. It visibly brightens the skin, evens out tone, and works to smooth the appearance of fine lines. Vitamin C is a powerful antioxidant that helps defend against visible signs of skin stress caused by environmental factors such as pollution and sun exposure.
Glycolic Acid (AHA)
As an Alpha Hydroxy Acid (AHA), Glycolic Acid gently exfoliates dull skin, revealing instant radiance and contributing to a more even complexion. It works by lifting off dead skin cells, allowing newer, fresher skin to surface.
Acerola Seed Extract
This extract provides additional antioxidant benefits and hydrates the skin, further amplifying its natural radiance. Acerola Seed Extract is known for being high in Vitamin C, helping to combat sallowness and target dark spots.
Purple Tea Extract
Harnessing the power of Clarins' NEW [Evenness Boosting Technology], Purple Tea extract, rich in antioxidants and polyphenols, promotes an even complexion. This potent plant ingredient grows at high altitudes and is exposed to harsh UV rays, prompting it to produce protective compounds that help prevent oxidative stress.
Niacinamide
Also known as Vitamin B3, Niacinamide helps to revive dull skin and provides antioxidant benefits, visibly reducing the appearance of dark spots and contributing to a more uniform skin tone.
Organic Sea Lily Extract
This extract works to combat dullness, contributing to a brighter and more revitalized complexion.
Organic Elder Extract
Included for its soothing properties, this extract helps to calm the skin.
