Details

There are a lot of Vitamin C serums, but we’ve created a new gold standard. Our unique powerhouse formula features four potent antioxidants (Vitamin C, Polyhydroxy Acid, Feverfew and Green Tea Extract) in every drop for brighter, more radiant skin in just one week!

Immediately after applying this lightweight and easy-to-absorb formula, your skin will appear glowing and refreshed. After just one week, skin will appear brighter and more radiant. After just four weeks, fine lines & wrinkles are less apparent and skin begins to look less stressed. When used consistently after 12 weeks, skin will appear dramatically brighter, more even and youthful.* This is for anyone seeking Vitamin C in a formula packed with antioxidants to diminish the signs of aging skin. You’ll “C” the visible difference in your skin in no time.

Why It Works: The star ingredient is 15% Pure Vitamin C (L-Ascorbic Acid), a powerful skin brightener, selected for its effectiveness over Vitamin C derivatives featured in many Vitamin C serums. Our pure Vitamin C is uniquely paired with Polyhydroxy Acid (PHA)which gently exfoliates the skin’s surface to allow the Pure Vitamin C to absorb into fresh, renewed surface layers of skin.

Ingredients

Key Ingredients

15% Vitamin C:

Brightens appearance of skin discolorations to reveal a natural, radiant complexion. Helps visibly fade dark spots and dark patches.

2% PHA (Gluconolactone):

Found naturally in the skin and provides antiaging and gentle exfoliating benefits without sun sensitivity. Sensitive skin types, as well as those who have had recent superficial cosmetic procedures, will find comfort in this molecule’s gentle nature. Gluconolactone strengthens the skin’s moisture barrier leaving it more resilient, while also providing potent antioxidant benefits. Gluconolactone is a welcome choice for sensitive skin types or following recent superficial cosmetic procedures where the skin can be more sensitive.

1% Feverfew Extract:

Gentle botanical antioxidant supports protection against drying environmental aggressors.

Green Tea Extract:

Boosts Vitamin C antioxidant capacity.

How To Apply

Apply to clean, dry face, neck and décolletage every morning, and follow with a NEOSTRATA moisturizer.

Storage: Store upright in a cool, dark place and open with care as contents may be under pressure. Product color may change over time but remains effective.

Pro Tip: Use an SPF face cream every day - even when it's cloudy outside - to help fend off dark spots and uneven skin tone. For best results, choose a broad spectrum SPF of 30 or above and reapply sunscreen at least every 2 hours, more frequently for fairer skin types.

Complement your daily brightening regimen by adding Illuminating Serum in the evening. This multi-action face serum featuring Niacinamide and NeoGlucosamine helps target and visibly fade dark spots while diminishing uneven skin tone. 15% Vitamin C + PHA Serum and Illuminating Serum are our go-to power duo for brighter, more radiant looking skin.
