Different forms of Vitamin C

What is Ascorbyl Tetraisopalmitate
It's the newest form of Vitamin C, it's made by mixing Vitamin C with Isopalmitic Acid. What makes it different is it's ability to penetrate the skin faster than any other form of Vitamin C out there.
Here's the deal: your skin has a lipid (oil) protective layer that keeps moisture in and germs out. Water and oil do not mix and that's why anything water based needs the helping hand of a good delivery system to penetrate your skin.
Ascorbyl Tetraisopalmitate is soluble in oil so it easily penetrates to the dermis offering the following benefits:
Fights free radicals that cause premature ageing
Boosts collagen production, keeping skin firm
Increases UV protection, helping to reduce sun damage
Lightens dark spots and discolorations
Not irritating like other forms of Vitamin C
Basically, it does what other forms of Vitamin C do, but better! Ascorbyl Tetraisopalmitate is one of the most powerful forms of Vitamin C and COSMED Vit C30 Serum contains a whopping 30%....
A rich facial serum, the vitamin packed solution is both potent and effective, whilst being kind to skin. Like other forms of Vitamin C, it helps prevent cellular aging by inhibiting the cross-linking of collagen, oxidation of proteins, and lipid peroxidation. It also works synergistically with the antioxidant Vitamin E, and has demonstrated superior percutaneous absorption and stability. Many studies have confirmed the skin lightening, photo-protective, and hydrating effects it can have on the skin.
