Who is it recommended for?
This serum is ideal for:
- All skin types and tones, including sensitive skin
- Individuals experiencing dehydration, fine lines, and wrinkles
- Skin showing signs of loss of firmness, elasticity, and volume
- Anyone looking for a plumping and repairing serum with visible results
In addition, its high tolerance makes it suitable for daily use in both morning and evening routines.
A powerful formula with 4 types of hyaluronic acid
At the heart of this serum lies an innovative 4-hyaluronic acid complex, specifically designed to act at multiple levels of the skin. Therefore, it provides both surface hydration and deeper plumping effects.
4 forms of hyaluronic acid
This advanced system combines different molecular weights to ensure enhanced penetration from the surface to deeper layers of the epidermis. As a result, it helps to:
- Intensely hydrate the skin
- Visibly plump and smooth wrinkles
- Improve overall skin texture and suppleness
Vitamin B5 (Panthenol)
At the same time, Vitamin B5 supports the repair of the skin barrier. Consequently, it helps soothe the skin and improve resilience, especially in dehydrated or sensitized conditions.
Madecassoside
Additionally, this ingredient—derived from Centella Asiatica—helps support skin regeneration and reinforces the repairing action of the formula.
