This potent Retinol serum delivers skin-renewing benefits via optimally concentrated Encapsulated Nano Retinol for maximum results with minimal irritation risk.

Retinol is highly recognised as a very effective vitamin for anti-ageing treatment due to its capacity to stimulate collagen production, accelerate cell reproduction and normalise skin keratinisation. Its regular application significantly improves skin elasticity, smoothness, and softness, resulting in younger, clearer and healthier-looking skin.

Nevertheless, Retinol is highly sensitive to oxidation, degradation in air, sunlight, acidic conditions, and heavy metals, resulting in decreased efficacy and formula discolouration.

NV Retinol is an encapsulated active ingredient in lipid particles with a diameter larger than 200nm. The encapsulated active ingredient is fully stable and, after permeation in the skin, oxidises and becomes a retinoic acid, ensuring more extraordinary results.

This technologically advanced combination of Encapsulated NV Retinol and Ceramide Complex and the new extraordinary GKHUG10™️ (Sodium Hyaluronate Crosspolymer) encourages the skin's renewal process with prime efficacy.

It improves skin tone and texture, assists in collagen production, and reduces the appearance of fine lines and wrinkles to create a vibrantly youthful and healthy-looking complexion.

Studies show that Centella Asiatica isn't just a fad—it does have benefits for the skin, thanks to its active compounds, including madecassoside, which serves as an antioxidant.

A dose of AZULENE minimises redness and irritation and mitigates the Retinol's effects.

GKHUG10™️ (Sodium Hyaluronate Crosspolymer): Excellent moisturising abilities. It is also a scavenger of damaging free radicals. Cross-linked Hyaluronic Acid,
Inspired by Dermatologists.

GKL40™️ - is a proprietary blend of self-emulsifying silicone fluids.
Emollient; provides dry smoothness, soft-focus / line blurring effect.

GKL42™️ CERAMIDE COMPLEX - is a multi-lamellar system of
vegetable-derived, semi-synthetic ceramides, cholesterol, free fatty acids
Phyto-sphingosine. Identical to lipids found in the skin, it has been
concentrated and formulated into a structure researched to provide
enhanced skin moisturisation and protection. Ceramide Complex restores
the skin's protective barrier functions and offers enhanced delivery and
exchange of skin lipids, especially suitable for dry skin, ageing skin and
sensitive skin.
