The Resurfacing Serum
15% Glycolic Acid
A leave-on exfoliating acid blend that resurfaces texture without the over-exfoliated tightness most 10%+ formulas leave behind.
Every formula at Gilt Skin ships with its exact active percentages printed on the box — no proprietary blends, no fragrance catch-alls, no guessing what you're actually paying for. Just dermatologist-reviewed actives, dosed at the concentration the studies used.
A leave-on exfoliating acid blend that resurfaces texture without the over-exfoliated tightness most 10%+ formulas leave behind.
Stabilized, pH-correct vitamin C with ferulic acid and vitamin E for brightening that doesn't oxidize orange in week two.
A 1:1:1 ceramide-cholesterol-fatty acid ratio that mirrors your skin's own lipid matrix, formulated for compromised, retinoid-stressed barriers.
Retinaldehyde converts to retinoic acid in fewer steps than retinol, so you feel results sooner without the week-three purge spiral.
Non-nano zinc with zero white cast on deeper tones, tested under a dermatologist panel across nine skin tones.
Walk into most skincare aisles and you'll find "proprietary complex" doing a lot of quiet work — a phrase that lets a brand put 0.1% of an active next to a hero ingredient on the front of the box. We built the Index instead: a public, batch-coded ledger of exactly what's in every Gilt Skin formula, at exactly what concentration, sourced from exactly which supplier.
It's slower to formulate this way. Every new percentage has to clear an internal irritancy review before it ships. But it means when we say 15% glycolic acid, we mean 15% glycolic acid — not 15% of a blend that's mostly water.
No phthalates, parabens, sulfates, or synthetic fragrance. Formulated and batch-tested in an FDA-registered facility. Full INCI deck at giltskin.com/index/vitamin-c.
You don't need eleven steps to see a difference. Every Gilt Skin routine is built around one resurfacing or repair active, one barrier step, and SPF — the rest is optional. Pick the one that matches the time you actually have at the sink.
Every routine ships in one box with a printed AM/PM card and arrives pre-sequenced by pH, so you're never layering a 3.2 pH serum on top of a 7.0 pH cream by accident.
Four checkpoints, none of them outsourced, all of them published internally.
Single-origin actives from audited suppliers — we visit the Provence lavender farms and the Swiss biotech labs ourselves, not through a broker.
Built in-house by two cosmetic chemists, not a contract lab running the same base for forty other brands with a different label slapped on.
Independent dermatological and in-vitro irritancy panels on every formula before it's allowed to leave the lab, repeated each time we change a percentage.
Small-batch runs in glass and PCR plastic, lot-coded the day they're filled so every jar can be traced back to its exact formulation date.
A plain-language field guide to the six molecules that show up most often across the Index — what they do, and which Gilt Skin formula carries them.
A plant-derived retinol alternative that signals the same skin-renewal pathways without the photosensitivity — our daytime-safe answer for clients who can't tolerate retinoids.
Found in: The Daily Edit serum lineOriginally a clinical anti-clotting compound, now one of the most effective actives for stubborn, hormonal hyperpigmentation that vitamin C alone can't touch.
Found in: The Vitamin C ConcentrateA lightweight, plant-derived lipid nearly identical to the squalene your own skin produces, restoring softness without sitting heavy or clogging pores.
Found in: The Barrier CreamCalms visible redness, tightens the look of pores, and strengthens the barrier — one of the few actives gentle enough to pair with almost anything else.
Found in: The Barrier CreamA 1:1:1 ratio of ceramides, cholesterol, and fatty acids that mirrors your skin's own lipid matrix to rebuild a barrier that's been stripped by actives.
Found in: The Barrier CreamA wound-healing herb used in traditional medicine for centuries, now backed by modern studies on redness reduction and post-procedure recovery.
Found in: Eye Repair ConcentrateNo "clinically proven" without a clinic. Every number below comes from an independent panel, not an in-house marketing survey.
"I've recommended a lot of skincare lines to clients and I've never seen a brand publish full INCI percentages like this. It's the kind of transparency that makes my job easier."
"Six weeks on the Daily Edit and the texture difference is the first thing people comment on, not a filter."
