The revolutionary Italian biorevitalization system — a family of three topical treatments that deliver collagen, lift & glow without needles or downtime. Reviv Beauty is one of Sanford’s only authorized PRX providers, and Kristen-Anne Thomas, FNP-BC, personally administers every session.
PRX is a family of Italian topical biorevitalization treatments — a patented blend of 33% TCA, hydrogen peroxide, and kojic acid that stimulates collagen and brightens skin without needles, downtime, or visible peeling. Reviv Beauty in Sanford, FL carries all three PRX tiers: PRX Derm Perfexion (entry — prevention, fine lines, sensitive skin), PRX-PLUS (advanced — pigmentation, mature skin, deeper wrinkles), and PRX-C (Vitamin-C-loaded — radiance, environmental defense).
Pricing at Reviv: Derm Perfexion $300/session or $1,000 for the 4-pack (save $200). PRX-PLUS $300/session or $1,000 4-pack (save $200). PRX-C $350/session or $1,000 4-pack (save $400 — the best per-session value). Every aesthetic consultation is free with Kristen-Anne Thomas, FNP-BC — she will pick the right tier for your skin at consult.

The modern Vitamin-C-loaded variant for patients who want luminosity plus protection from pollution, blue light, and oxidative environmental stress.
All three PRX formulations share the same patented base — a controlled, non-traumatic wound-healing cascade that fires collagen and elastin from inside the dermis while leaving the protective skin barrier intact.
Developed in Italy and used by leading European clinics for over a decade, PRX delivers what dermatologists call biorevitalization: the skin’s own repair machinery is activated, fibroblasts ramp up, hyaluronic acid production rises, and the dermis rebuilds itself across 4 weekly sessions.
Because the epidermis is preserved, there’s no peeling, no sun sensitivity, and no recovery. You can apply makeup 1–2 hours later, train at the gym tomorrow, and return for treatment two next week. Refreshed, not raw. Each PRX tier — Derm Perfexion, PLUS, and C — tunes the same base for a different patient profile.
Trichloroacetic acid carries the actives into the dermis and triggers a controlled wound-healing cascade — without breaching the protective outer layer of skin.
At controlled concentrations, H₂O₂ activates fibroblasts (the cells that build collagen and elastin) without inflammation or surface damage.
A natural melanin inhibitor that fades hyperpigmentation, evens skin tone, and creates the signature PRX luminous finish — safely on every Fitzpatrick skin type.
