What is L-Ascorbic Acid?


Understanding active ingredients

L-Ascorbic Acid (LAA) is a chemically active form of Vitamin C and a well-established antioxidant. Humans lack the enzyme allowing for in vivo production of Vitamin C, so it must be obtained through other sources.


Due to low absorption rates when ingested, topical application remains the best delivery method for this important vitamin to the skin.

How does L-Ascorbic Acid work?

L-Ascorbic Acid is a powerful antioxidant that instigates and interrupts chemical reactions to aid health and recovery of cellular elements within skin. As an active ingredient L-Ascorbic Acid protects cells in the dermis and epidermis from the inside out. It holds multiple benefits for Aesthetic Dermatological use.


Key benefits of L-Ascorbic Acid

Decreased Oxidative Stress on a Cellular Level

LAA reduces and eliminates oxidative stress by effectively neutralizing free radicals. Free radicals can mutate and alter cellular DNA and lead to inflammation, signs of skin ageing, decreased elastin, destruction of proteoglycans and the breakdown of collagen.


Collagen Production

LAA is a critical component of collagen production across all age groups. As a co-factor for enzymes Prolysyl and Lysyl Hydroxylase, L-Ascorbic Acid links and stabilizes collagen molecules, regulates collagen production and stimulates the quantitative amount of collagen biosynthesized.



L-Ascorbic Acid effectively disrupts melanogensis. By inhibiting the enzyme Tyrosinase, LAA decreases melanin production for a favorable effect on hyperpigmentation creating bright, even-toned skin.



Actively inhibiting NFkB production positively influences the skin's inflammation response. This shortens the inflammation cycle, aids wound recovery and healing, diminishes skin redness, and treats Rosacea and Acne Vulgaris.


Photo protection

L-Ascorbic Acid’s unique UV-protective effect against UVA (320-400nm) and UVB (290-320nm) light spectrums (impossible to achieve using UV blockers only). LAA can stop formation of sunburn cells, photo-aging, UV damage to dermal cellular structures, and work to prevent some skin carcinoma's. *Vitamin C is not a replacement to UV blocking topical sunscreen.


Potential side-effects of L-Abscorbic Acid

Vitamin C is safe for daily dermatological use. Side effects are rare and mild when they do occur. Symptoms relate to the high acidity of L-Ascorbic Acid and may include dryness, itchiness, and or slight reddening of skin.


How is L-Ascorbic Acid used by Dermaceutic Laboratoire?
