Great for all skin types, vitamin C is the star ingredient because of its ability to increase collagen levels, reduce melanin production, brighten skin, and repair the effects of UV exposure and other environmental damage. Plus, unlike most vitamin C products, Melanie’s is incredibly stable and can withstand light and air exposure. That’s why it’s safe and active even in its clear bottle.

1. START WITH A DRY CANVAS
Wash your face, pat dry. If you use toners and thin serums, apply those, and let them dry first. Now it's Serum C time.
2. APPLY 5 TO 10 DROPS OF SERUM C
Basically, you want to use enough so that you can cover your entire face and neck. Lightly sweep Serum C around your face and up the neck, avoiding the eye area.
3. WAIT 5 TO 10 MINUTES
Serum C works wonders, but it doesn't play nicely with other active skincare ingredients. Give it time alone to do its job and create a glaze on your skin. You'll know when it's time to move on because Serum C will no longer feel slippery to the touch. I like to wait the full 10 minutes. I make a cup of tea, and get my clothes ready for the day. What would you do in these 10 minutes?
4. CONTINUE YOUR ROUTINE
For some people, Serum C is the last step in their skincare routine. If your skin needs more hydration, layer on your other products, always applying from thinnest to thickest.
Remember, Serum C is a treatment strength serum. This means itʼs highly concentrated. You can only use it once per day, from 3 to 7 days a week.
Tetrahexyldecyl ascorbate could be the key ingredient in making vitamin C products more versatile and easy to use. The active ingredient, tetrahexyldecyl is an oil-based stable form of vitamin C.
Current vitamin C products have a major problem. Only pure L-ascorbic acids, not vitamin C analogs, have been shown to improve skin appearance and reduce dull skin. Vitamin C in other forms tends to be less potent and is not as easily converted by the body into L-ascorbic acids. Tetrahexyldecyl-ascorbate seems to be different.
The benefit of tetrahexyldecyl ascorbate compared to L-ascorbic acid is that it is far more stable, less irritating, and can be easily formulated into oil-based products.
Tetrahexyldecyl ascorbate has a vitamin C activity approximately equal to that of L-ascorbic acid. However, since tetrahexyldecyl ascorbate is lipid-soluble (fat-soluble), it can penetrate the skin better than L-ascorbic acid and other water-soluble forms of vitamin C.
Unlike L-ascorbic acid, it does not readily degrade in formulas Tetrahexyldecyl ascorbate has a neutral pH of 7, which, while above the skin's natural pH, is far less irritating than the acidic L-ascorbic acid forms of vitamin C.
L-ascorbic Acid is generally considered to be a highly unstable ingredient. It often requires special packaging or formulation to keep it from degrading and losing its potency.
Tetrahexyldecyl ascorbate, which is a stable form of vitamin C, is more stable.
