This weightless oil serum adds a powerful brightening boost to your favorite moisturizer or facial oil with an 18% concentration of Tetrahexyldecyl Ascorbate - a revolutionary Vitamin C ester that is highly stable and non-irritating, even to the most sensitive of skin.

Vitamin C is known to increase collagen synthesis, protect the skin from UV damage, and reduce or even reverse uneven tone in the skin. This product contains both Vitamin E, which works synergistically with Vitamin C to prevent photo-damaged skin, and Rosemary Oleoresin, which works as a penetration enhancer to boost efficacy.

This product is formulated to be added to your favorite facial oil or moisturizer for a skin-brightening, age-defying boost, but is also safe for use if applied directly to the skin. We love it paired with our Blue Tansy & GLA Clarifying Day Oil; this product is recommended for AM use.

Add 3-5 drops into your favorite facial oil or moisturizer, mix well, and apply to the skin as usual. This serum can be applied directly to the skin if desired.

Recommended for daily use as part of your morning skincare routine; pairs wonderfully with our Blue Tansy & GLA Ultra-Clarifying Day Oil.

Tetrahexyldecyl Ascorbate, a very stable, non-irritating Vitamin C ester that has been shown to increase collagen synthesis at least twice as well as ascorbic acid, working to slow down skin aging while boosting brightness and clarity.

Vitamin E, a powerful antioxidant in its own right, works to boost the photo-protection qualities of Vitamin C when the two are paired together.

Rosemary Oleoresin, derived from the common rosemary plant, works as a penetration enhancer to increase the delivery of active ingredients deep into the skin.

Blue Tansy Essential Oil, known for its ability to calm and soothe irritated or problematic skin, reduces redness and clears breakouts and congestion.

About The Sunday Standard

Our epynomous skincare line was launched in 2018 in response to our founder's desire to create the skincare line she'd always dreamed of - one that would help to heal her painful, cystic acne at a cellular level, rather than simply minimize her current breakout while she waited for the next one to (inevitably) appear.

Formulated to provide the skin with the nutrients it needs to function optimally, and without the use of harsh hormone-disrupting ingredients, The Sunday Standard offers products that work to support the skin's lipid barrier, normalize the skin's natural oil production, reduce the occurrence of active breakouts, minimize and fade blemishes, and support healthy skin aging.

Our products are formulated with breakout-prone skin in mind, but work wonderfully to support healthy skin of all types through our gentle, non-comedogenic oil-based skincare system.
