Key Ingredients

VITAMIN Cg

Vitamin Cg, or Ascorbyl Glucoside, is a Vitamin C derivative that activates once absorbed into the upper layers of the skin’s surface. With antioxidant benefits, this form of Vitamin C is frequently used in anti-wrinkle skincare products to help reduce the appearance of lines.

FRAGMENTED HYALURONIC ACID

This fast-absorbing form of Hyaluronic Acid is known for its ability to hold up to 1,000 times its weight in water. The lower molecular weight and size is able to penetrate deeply and fill water reserves in skin.

GLYCERIN

Glycerin is a well-known, effective humectant. Within our formulae, it may help skin retain moisture and soften skin.

How to Use

Cleanse skin thoroughly prior to application
Apply anti-wrinkle serum over entire face twice daily (avoiding the eye area)
Can use alone or under your usual moisturiser
In case of contact with eyes, rinse thoroughly
As the formula blends into the skin, you may experience a feeling of warmth. This sensation is normal.
