Vitamin C – The most advanced technology to stabilize antioxidants
PHYTIC [TC] SERUM: A UNIQUE AND STABLE MOLECULAR COMBINATION
8% L-ASCORBIC ACID (vitamin C in its natural form)
- Skin surface: boosts epidermical cells turnover to enhance skin radiance and refine skin texture.
- At dermis level: significantly increases collagen and dermis component synthesis (1,2,3) to reduce wrinkles and improve skin structure.
- One of the most powerful antioxidants to protect skin cells against external agressions (UV, stress, pollution,…). This makes L-Ascorbic Acid a must-have to prevent skin aging.
- Anti-spot activity thanks to its antioxidant action and limitation of melanin transfer by the weakening of dendrites (4).
2% PHYTIC ACID
- Powerful antioxydant and anti-cancer (5)
- Anti pollution (chelates iron and scavengers heavy metals)
- Regulates pigmentation and normalises skin sebum rate (6)
- Synergistic stabilization action with L-ascorbic acid.
0,2% TANNIC ACID
- Powerful antioxidant, neutralises pro-oxydative Fenton reaction (7)
- Chelates iron and anti-pollution effect
- Stimulates collagen synthesis
COMPARATIVE TECHNIQUES TO STABILIZE L-ASCORBIC ACID (VITAMIN C)
L-ascorbic acid (vitamin C in its natural form) is highly unstable in contact with air and water oxygen, especially with warm temperature.
Different techniques are used to stabilize it with unequal results.
ADVANTAGES
DISADVANTAGES
ALPHASCIENCE TECHNOLOGY
BIOMIMETISM – INSPIRED BY NATURE
Molecular combination of L-ascorbic acid with powerful antioxidants.
Excellent stability in the skin and with heat.
Efficiency and bioavailability.
Complex formulas
Encapsulated L-ascorbic acid
Easy to formulate
Limited to medium concentrations (3 to 4%).
Low stability.
Vitamin C derivatives (ascorbosilane, sodium ascorbyl phosphate, etc)
Easy to formulate
Low anti-aging and antioxidant efficiency.
Dry form of L-ascorbic acid (powder) to mix with a solution before use
Easy to formulate.
Stable before mixing.
No guarantee of stability after mixing.
Weak penetration. Uneasy for patient.
BIOMIMETISM: ALPHASCIENCE IS INSPIRED BY NATURE TO STABILIZE ANTIOXIDANTS
How do fruits which contain a lot of water manage to keep their vitamin C and antioxidants content stable and active?
L-ascorbic acid (vitamin C in its natural form) is fully stable in an orange for example, because it is associated with other antioxidants such as polyphenols and flavonoids.
This assemblage forms a complex chemical structure that is totally stable dynamically.
ALPHASCIENCE STABLE MOLECULAR COMBINATION
By observing nature and thanks to our control of the chemical interactions between antioxidants and Vitamin C, we developed a unique associative complex of powerful antioxidants which ensures the stabilization of highly concentrated L-ascorbic acid.
