C-15 Serum

C-15 Serum
Size: 1 oz

Prefer C | C-15 Serum is a thin, absorption-enhanced, 15% acid-C treatment that plays a pivotal role in collagen synthesis and in preventing the signs of aging.

Prefer C is freshly prepared per order to maximize shelf life while avoiding unpleasant and/or synthetic solvents and petrochemicals commonly used to replace water in ascorbic acid serums. Brand new serum begins as a champagne-colored liquid that darkens over time. For maximum potency, use within 2-3 months, or before serum begins to leave a visible (washable) tint upon application.

Directions for use: Apply a pump to entire clean face and neck at least once daily. For best result, wait 10-15 minutes before following with additional treatment and/or moisturizing products.

It is possible for particularly sensitive skin types to find acid C serums irritating, and may want to opt for a different form of C. Because of C-15’s acidic nature, it should not be immediately followed by (or immediately applied over) products containing niacinamide to avoid experiencing symptoms associated with a localized niacin flush. These can include temporary tingling, itching, and redness at the application site for some people.
