88 ASCP Skin Deep Summer 2025 ESTY PROTOCOLS Radiance Reimagined A vitamin C protocol for restorative results by Circadia ENVIRONMENTAL DAMAGE, STRESS, AND TIME can dull even the healthiest skin. As we age, natural levels of vitamin C decline and it becomes harder for our bodies to replenish them through diet or supplements. At the same time, external factors—ultraviolet (UV) rays, pollution, lifestyle, and oxidative stress—trigger infl ammation that leads to collagen degradation, hyperpigmentation and barrier impairment. This translates to an increase in dark spots, sagging, fi ne lines, and an uneven skin tone. Fortunately, topical vitamin C remains one of the skin's most powerful allies, helping to restore clarity, fi rmness, and glow. The Radiance Facial is a high-performance treatment powered by a blend of four bioavailable vitamin C derivatives—each selected for their stability, permeability, and effi cacy. Enhanced with enzymatic exfoliants and phytoactives, this treatment delivers immediate luminosity without downtime while addressing long- term skin health at the cellular level. THE FOUR C'S OF CLINICAL EXCELLENCE To better understand the eff ectiveness of this treatment, let's review four key elements: collagen, clarity, calming, and correction. Collagen Collagen, the skin's primary structural protein, declines with age and UV exposure. The Radiance Facial stimulates fi broblastic activity within the dermis, supporting neocollagenesis through ascorbic acid's role as a cofactor in pro-collagen synthesis. This leads to improved tensile strength, dermal thickness, and overall elasticity. The result? Smoother, fi rmer, and more youthful-looking skin texture. Clarity Uneven skin tone, melasma, and photodamage stem from irregular melanogenesis. The Radiance Facial employs multiple forms of vitamin C to inhibit tyrosinase—the rate-limiting enzyme in melanin production—while simultaneously protecting against reactive oxygen species. The multitiered delivery allows for melanin modulation across both superfi cial and basal layers, producing a visibly brighter and more uniform complexion with each application.
