    This brightening vitamin C serum works to diminish the appearance of hyperpigmentation and sun damage, improving the skin’s overall texture and tone. It promotes collagen synthesis, which repairs and strengthens the skin, and also provides antioxidant protection against environmental stressors, like UVA and UVB rays. It uses THD ascorbate, an advanced form of vitamin C that penetrates the skin on a deeper level than other common forms of vitamin C, making it all the more effective. Plus the emollient-rich formula helps to smooth out and temporarily plump fine lines and wrinkles.

    • This serum uses THD ascorbate, a form of vitamin C that’s been shown to enhance the effects of retinol. It also penetrates the skin on a deeper level than L-ascorbic acid, a form of vitamin C commonly used in skin-care products.
    • Unlike many vitamin C serums, this formula doesn’t contain water, meaning it won’t oxidize and turn brown over time.
    • A.M./P.M.

    Massage one or two pumps of serum onto a cleansed face and neck. Use daily, both morning and night.

    • RealSelf tips:

    • Serums work best when applied to clean skin. To increase product absorption, cleanse the skin with VI Derm Beauty Gentle Purifying Cleanser before application, to remove dead skin cells and other impurities.

    • To enhance the effects of a retinol treatment such as VI Derm Beauty Retinol Age-Defying Treatment Moisturizer, apply this serum first.

    • After an injectables treatment, apply this serum daily, to reduce oxidative stress and stimulate fibroblast activity.

    • This serum can be used daily, in between microneedling treatments, to protect the skin and prevent new hyperpigmentation formation.

    • This serum can be used to repair thermal damage two days following a laser procedure and should be used daily, for two to three weeks thereafter.
