Guaranteed safe and effective through extensive research and development, the main ingredient “Vitamin C derivative” is one of the nine whitening ingredients which are approved by the Ministry of Health, Labor and Welfare of Japan.

Highly effective for:
* Skin Whitening – inhibits activity of intracellular Tyrosinase and Melanogenesis due to harmful UV rays.
* Anti- Aging- Prevent DNA damage due to harmful UV rays.
* Skin Rejuvenation- Prevents acne and heals acne scars.
* Moisturizing- Sooth and rehydrate cracked skin. Sodium Hyaluronate is also added.

Derma CELESTY Cogent-C Cream is using “oil-soluble” Vitamin C derivative.

Why “oil-soluble?”
Vitamin C derivative is used in most other skin care products which are “water-soluble”.

However, “water-soluble” Vitamin C derivative is poorly absorbable into skin, and the effect does not last long. “Oil-soluble” Vitamin C derivative, on the other hand, can penetrate deeply into skin layers, and stays effectively much longer. CELESTY has successfully developed a safe and stable serum with oil-soluble Vitamin C derivative.
