L-Ascorbic Acid is The Best Vitamin C for Your Skin


" L-ascorbic acid has exactly the same molecular structure as vitamin C found in fruits and vegetables."


Naturally found in many fruits and vegetables, vitamin C (ascorbic acid) is one of the most tried and tested super-antioxidants. The health and skin benefits of vitamin C have been proven in countless studies. Vitamin C strengthens immune system, protects cells from environmental damage and premature ageing.

Skincare formulators have been using vitamin C for decades, however, vitamin C is prone to oxidation upon contact with water and oxygen. To make it more stable, cosmetic scientists have created different forms of vitamin C, known as vitamin C derivatives such as sodium ascorbyl phosphate, magnesium ascorbyl phosphate, ascorbyl palmitate, tetrahexyldecyl ascorbate, glyceryl ascorbate and ascorbyl glucoside. Some of these vitamin C derivatives are oil-soluble, nevertheless, the question remains the same, which form of vitamin C is best for the skin?

L-Ascorbic Acid is The Best Form of Vitamin C for The Skin

Scientifically known as the purest form of vitamin C, L-ascorbic acid has exactly the same molecular structure as ascorbic acid, the natural vitamin C found in fruits and vegetables. Numerous studies showed that L-ascorbic acid is the most active and potent form of vitamin C. It stimulates collagen synthesis in the skin, prevents and reduces photoageing, and improves the appearance of acne-prone skin.

L-Ascorbic Acid Has Excellent Anti-Free-Radical and Anti-Pollution Activity

As a potent antioxidant, L-ascorbic acid neutralises free radicals and protects skin from pollutants in the environment. The efficacy of L-ascorbic acid in preventing oxidative skin damage is further enhanced by combining it with vitamin E (The Roles of Vitamin C in Skin Health, Nutrients, 2017).

L-Ascorbic Acid Promotes Collagen Synthesis in The Skin

The collagen-boosting properties of L-ascorbic acid are well-known among medical scientists. According to researchers at Linus Pauling Institute, Oregon State University, vitamin C (ascorbic acid) is a crucial nutrient for healthy skin. Studies showed that L-ascorbic acid can penetrate the skin, hence, it is one of the most effective anti-ageing skincare ingredients.

L-Ascorbic Acid Protect The Skin from Photoageing

A clinical trial by a group of scientists as published in the Experimental Dermatology showed that L-ascorbic acid has excellent photo-protective properties that help prevent and reverse UV-induced skin ageing. During the 6 month study, vitamin C was shown to visibly reduce the appearance of wrinkles.

The efficacy of L-ascorbic acid in preventing sun-induced skin damage is further boosted when it is mixed with ferulic acid and vitamin E (The Journal of Investigative Dermatology, 2005).

L-Ascorbic Acid Lightens Pigmentation Spots

A systematic review of 22,580 scientific articles on vitamin C (Journal of Oral and Maxillofacial Pathology, 2020) indicated that L-ascorbic acid is effective at reducing the appearance of pigmentation spots. Studies showed that it reduces the excess melanin production in the skin. L-ascorbic acid neutralises UV-induced free radicals, hence, it also prevents the excess melanin production due to sun exposure.

L-Ascorbic Acid in Skincare Formulas

Compared to vitamin C derivatives, L-ascorbic acid has a significantly higher bioactivity in the skin. However, it has to be stabilised to prolong its skin benefits. As a skincare scientist, I have over 15 years experience working with vitamins and other active ingredients. I use stabilised vitamin E, ferulic acid and other ingredients to protect, stabilise and boost the efficacy of L-ascorbic acid in skincare formulas.

Henry Tianus multi-award-winning vitamin C serum, Antioxidant Youthful Essence has been specially formulated with L-ascorbic acid, ferulic acid, stabilised vitamin E, pro-vitamin B5, turmeric, ginkgo and lavender plant extracts to protect skin from free radicals, pollution and premature signs of ageing including UV-induced pigmentation spots. For best results, apply this serum on freshly cleansed face and neck, morning and evening. Follow with with your usual moisturiser. Suitable for all skin types, men and women.
