For: Dull & Uneven-Looking Skin
The next step after viral basics: a formulation-focused stack of vitamin C and niacinamide on a sea buckthorn base.
Many vitamin C serums are either too weak to notice or too sharp for daily use. Dull skin needs something you will actually use every morning.
Eclat du teint Vitamin C Booster Ampoule · 30ml
Sea buckthorn extract, niacinamide and pure vitamin C in a creamy booster ampoule.
Sea buckthorn fruit extract replaces water as the first ingredient. Niacinamide and ascorbic acid (pure vitamin C) are fourth and fifth, followed by five forms of hyaluronic acid, coptis japonica root extract and adenosine. Part of our professional line for clinic and spa use as well as home routines. Selected by our in-house pharmacist after a full ingredient review.
What You Feel First
Within 10 Minutes
Skin feels smooth and hydrated with a soft, creamy finish.
Next Morning
Skin looks fresher and more radiant.
The Concern We Hear Most
"Will vitamin C sting or irritate my skin?"
Ascorbic acid is the pure form of vitamin C, and some skin feels a slight tingle at first. Here it sits alongside niacinamide in a creamy base rather than a watery acid serum. Start every other day if your skin is sensitive, and always follow with SPF in the morning. It contains added fragrance.
Week by Week
Days 1–3
Skin feels hydrated and smooth.
Week 1
Skin looks more radiant.
Week 2
Skin tone looks more even.
Week 4
With daily use and SPF, skin looks brighter and more even. Individual results may vary.
The Ingredients Behind It
Ascorbic Acid (Vitamin C)
The pure form of vitamin C, listed fifth. It is one of the best-known ingredients for a brighter-looking complexion.
Niacinamide
Vitamin B3, listed fourth, for the look of even tone and smooth texture.
Sea Buckthorn
Hippophae rhamnoides fruit extract, used as the base in place of water.
Hyaluronic Acid ×5
Five forms of hyaluronic acid help skin feel hydrated, alongside adenosine and coptis japonica root extract.
Skin Type Fit
More Than a Serum
Vitamin C in the morning, under SPF, is one of the simplest habits for brighter-looking skin. In the treatment room, it works as the active step of a brightening facial.
Vitamin C and niacinamide, in a form you will use every day.

"Pure vitamin C and niacinamide, both high in the list, in a creamy base that suits daily use."
