Firmness and elasticity: REDEFINER Serum
The power of epigenetics in your skin

Skin aging is a natural process, but it can be slowed down with the right serum. REDEFINER is designed to improve firmness and elasticity thanks to its powerful blend of active ingredients (Epigencur), which activates the skin’s natural regeneration mechanisms.
Its advanced formula helps stimulate the production of collagen and elastin key elements for maintaining firm, flexible skin. With regular use, expression lines appear smoother, the skin looks more toned, and its texture becomes more even and refined.
Recommendation: Apply to clean skin morning and night, gently massaging with upward movements to enhance absorption. Ideal for mature skin or skin showing early signs of sagging that is looking for deep, visible anti-aging care.
Regenerative Nourishment: MELATOGEN Serum
Melatonin and Epigenetics at the service of the Skin

The MELATOGEN serum combines intensive nourishment with active ingredients that respect the skin’s biological rhythms. This means its actives work in sync with the skin’s natural regeneration cycles, enhancing repair overnight and protection during the day.
This regenerating serum delivers luminosity, elasticity, and an immediate revitalizing effect, making it ideal for dull skin that needs a deep nutritional boost. In addition, it helps restore the skin barrier, increasing the skin’s resilience against external aggressors.
Recommendation: To maximize its benefits, pair the MELATOGEN serum with the REDEFINER cream if firmness is also your goal. This combination helps keep the skin nourished, flexible, and comfortable throughout the day.
High-Potency Antioxidants: NOX+ BIOBOOST
Slowing Down Cellular Aging

Oxidative stress and free radicals are responsible for much of premature skin aging. NOX+ BIBOOST is a biphasic serum enriched with high-potency antioxidants that work synergistically.
With a regular use, it improves firmness, boosts radiance, and helps protect the skin from pollution and environmental stress. This serum is ideal for skin that needs active defense against external factors that accelerate the loss of vitality and elasticity.
Recommendation: Can be applied in the morning and at night.
Glow and daily protection: NOX 3C
Three types of Vitamin C for an instant glow

NOX 3C combines three types of vitamin C (encapsulated, free, and stabilized) that work in synergy to brighten the skin and even out tone. Its advanced formula helps reduce signs of fatigue and delivers a natural glow that visibly improves skin texture.

Multilayer hydration that protects against digital aging: BLUMOIST Serum
Technological skins
