Brigthening Boost Vitamin C Powder Refill

What it is: A Brightening Boost Vitamin C Powder Refill to use in Exponent's refillable two-part Power Serum Powder Dispenser (sold separately). This clinical-grade formula helps visibly boost collagen and deliver powerful nourishing and anti-aging benefits.

Who it's for: Ideal for all skin types, even sensitive skin. Ideal for those concerned with fine lines, wrinkles or dry skin; extra gentle enough for sensitive skin.

What it does: This clinical-grade, anti-aging serum powder is powered by 10% L-ascorbic acid (pure vitamin C) and softly buffered with multiweight hyaluronic acid to help hydrate and smooth the skin. Unlike traditional pre-mixed serums that degrade and lose potency, this two-part formula is activated fresh for peak effectiveness and clinical results. In clinical testing on subjects screened for sensitive skin, it was proven to visibly reduce fine lines, wrinkles, sunspots and discoloration within weeks—without irritation. The result: smoother, more radiant, fresh-looking skin that feels firmer and deeply hydrated.

Key ingredients:

- 10% L-ascrobic acid: the pure form of vitamin C, is an antioxidant that wards off oxidative stress and free radicals while promoting collagen production—helping to prevent fine lines and wrinkles, sunspots and discoloration for a brighter, more radiant complexion

Research results:

Based on a clinical test study with measured instrumentation of 28 subjects evaluated with a Visia Image Analysis Pro over 4 weeks:

- 72% of subjects had an increase in skin firmness in 4 weeks

- 66% of subjects had an increase in brightness and a decrease in discoloration in 4 weeks

How to use: The Brightening Boost VItamin C Powder Refill should be used in Exponent's refillable Power Serum Powder Dispenser as a refill for a previously purchased Power Serum. Brightening Boost is best used as the first layer on clean, damp skin in the morning. Layer underneath a moisturizer or SPF. Note that L-ascrobic acid is water-loving, so allow serum to dry down before layering oil-based moisturizer or makeup products. It can be used once a day.
