MADE WITH
Pure Vitamin C
L-Ascorbic Acid, also known as Pure Vitamin C, is a highly efficacious antioxidant known for its ability to improve the appearance of skin aging. In addition to antioxidant protection, Pure Vitamin C is known to help boost radiance, improve texture and visibly reduce the appearance of lines, wrinkles and other signs of aging. Pure Vitamin C has many benefits including, the ability to gently exfoliate dead skin cells to reveal a brighter-looking skin, helping prevent uneven skin tone and stop pigmentation from producing so your complexion can appear brighter and clearer. Not only that, Vitamin C is a powerful antioxidant, which means it can neutralise environmental aggressors like UV rays and pollution from creating free radicals on your skin that cause premature signs of visible aging, making it a great choice for anti-wrinkle and anti-aging skincare.
Vitamin Cg
Vitamin Cg, also known as Ascorbyl Glucoside, is a Vitamin C derivative which can penetrate the upper layers of the skin's surface and frequently used in anti-wrinkle skincare products. It acts as a powerful antioxidant that works well with other replenishing and antioxidant ingredients to further improve the skin radiance, creating a smoother, clearer and more invigorated looking.
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. Acting like a sponge, it draws moisture into skin’s surface layers and expands as it absorbs. Hyaluronic Acid is known to help smooth and plump fine lines and is commonly used in skincare products intended to visibly reduce facial lines and refine texture.

Vitamin C Myths Debunked
- Your Skin Needs Topical Vitamin C - Not Just Oranges
Fact: "While skin cells do not have the ability to produce Vitamin C, the ingredient is an essential part of collagen production. Therefore, in addition to eating a diet rich of the potent anti-oxidant, it is important to apply a topical Vitamin C to return skin to a healthy state and reduce the appearance of aging. " Dr. Geyer Kiehl's consulting Dermatologist - Vitamin C is For Any Skin Type, at Any Age
Fact: "I recommend Vitamin C products not only to my patients who are looking for solutions to correct signs of aging, but also those who want to prevent the aging process from starting early. Vitamin C is one of the best known anti-oxidants, protecting skin against UV damage caused by free radicals."Dr. Geyer Kiehl's consulting Dermatologist - Topical Vitamin C Should Only Work at Night
Fiction: "Before my patients leave their door, I tell them to apply an anti-oxidant rich product and an SPF 50 or higher. Vitamin C is a great anti-oxidant that provides a second layer of defense after sunscreen by neutralizing free radicals that can damage skin, accelerating signs of aging."Dr. Geyer Kiehl's consulting Dermatologist
