15 minutes of stable Vitamin C — fade dullness, brighten dark spots, glow without sting.
3-O-Ethyl Ascorbic Acid is the form of Vitamin C that actually stays Vitamin C — pure L-AA oxidizes in days, this one stays stable for months and converts to active Vitamin C on contact with skin. Pair with 4% glycerin (humectant moisture) and allantoin (post-procedure calm) for a 15-minute mask that delivers a measurable lift.
“Most Vitamin C serums oxidize before you finish the bottle. 3-O-EAA doesn't.”

3-O-Ethyl Ascorbic Acid
Converts to active Vitamin C on contact with skin. Doesn't oxidize like pure L-AA, doesn't sting sensitive skin, and pregnancy-safe. Targets tyrosinase to fade hyperpigmentation.
Glycerin (4%)
High-concentration humectant — pulls water from the air into your skin during the 15-minute treatment. Plumps fine lines, restores dull texture.
Allantoin
A clinical-grade soother used in post-procedure skincare. Keeps skin calm while the Vitamin C works on pigmentation.
Yuzu (Citrus Junos)
Japanese citrus, rich in natural Vitamin C and flavonoids. Supports the brightening pathway without irritation.
3-O-EAA. The form of Vitamin C that actually stays Vitamin C.
Pure L-Ascorbic Acid is brilliant on paper and a disaster in a bottle — it oxidizes within days of opening, turns brown, loses potency, and stings sensitive skin. 3-O-Ethyl Ascorbic Acid (3-O-EAA) solves all three problems.
It's a stable derivative that converts to active Vitamin C the moment it meets your skin. Better-tolerated than L-AA. Pregnancy-friendly. Doesn't oxidize on the shelf. In this mask, 3-O-EAA targets tyrosinase to fade dark spots, while 4% glycerin floods moisture into the skin and allantoin keeps everything calm for the full 15-minute treatment.
“Pure Vitamin C is brilliant on paper. 3-O-EAA is brilliant in the bottle.”

3-O-EAA (the stable Vit C), 4% glycerin, allantoin calm.
Built by a Latina mother for the skin nobody was formulating for.
I built Turimere because no one was making real brightening for melanin-rich skin that was also safe during pregnancy. This mask uses 3-O-EAA — the form of Vitamin C my dermatologist trusted, the one that doesn't sting and doesn't oxidize. 15 minutes, once a week, real glow.
Brighten without the oxidation problem.
