E15 GLOW is our everyday-radiance answer for people who want true Vitamin C results without the high-maintenance fragility of pure L-Ascorbic Acid. Rather than chasing the highest possible acid percentage, we built the formula around 3-O-Ethyl Ascorbic Acid (EAA) - an exceptionally stable, water-soluble Vitamin C that the skin converts directly into pure ascorbic acid. Synergized with a clinical 0.5% dose of Botanical Ferulic Acid and 0.25% Sunflower Vitamin E, this derivative brightens dull skin, fades the look of uneven tone, and reinforces the antioxidant network - all at a comfortable, skin-friendly pH. Cushioned with Allantoin, Panthenol, and Snow Mushroom and driven by our green-chemistry transit system, this daily dose absorbs instantly without leaving a single trace of sticky or greasy film.

Pure L-Ascorbic Acid is the gold standard - but it is notoriously high-maintenance. It demands a harsh, low pH that stings reactive skin, and it oxidizes the moment it meets air, turning serums orange, then brown, and stripping them of potency within weeks. To mask this instability, legacy brands either drown the acid in barrier-destroying denatured alcohols to force absorption, or they suspend it in thick, waterless silicone and oil bases that suffocate the pores. The result is a product that carries the offensive "hot dog water" scent, pills (rolls up into tiny flakes or balls) under makeup, and is half-dead before you finish the bottle.

We Do Things Differently

We engineered E15 GLOW for stable, everyday Vitamin C with flawless sensory elegance. By building around 3-O-Ethyl Ascorbic Acid instead of raw L-Ascorbic Acid, we eliminated the violent oxidation and harsh pH entirely - this serum holds its potency far longer and treats reactive skin gently. Relying on an advanced green-chemistry transit system of DMI and Propanediol, we completely bypass the need for gritty silicones, waterless oil bases, and barrier-stripping alcohols. The result is an odorless, water-light glow serum that glides on like water, sinks in rapidly, leaving the skin dry to the touch in under two minutes, and leaves your face feeling entirely bare, breathable, and perfectly primed for seamless sunscreen and makeup application without a single flake of pilling.

The Core Active

15% 3-O-Ethyl Ascorbic Acid: A maximum-strength 15% payload of the most stable Vitamin C derivative available. Because it is water-soluble and oxidation-resistant, it delivers powerful, consistent brightening that the skin converts into pure ascorbic acid - without the stinging or rapid degradation of raw L-Ascorbic Acid.

The Antioxidant Synergizers

0.5% Botanical Ferulic Acid & 0.25% Purified Sunflower Vitamin E: The clinical-standard 0.5% Ferulic Acid and a 0.25% Vitamin E micro-dose reinforce the entire antioxidant network, doubling the photoprotective power of the Vitamin C while keeping the formula biologically stable.

The Recovery Complex

0.5% Panthenol & 0.4% Allantoin: A 0.5% Panthenol dose and an aggressive 0.4% Allantoin payload soothe the skin on contact, calming any reactivity and accelerating tissue repair while the Vitamin C works.

The Advanced Transit & Base Matrix

Propanediol & Dimethyl Isosorbide (DMI): A targeted green-chemistry solvent network of 7% DMI and 6% Propanediol that drives the brightening payload deep into the tissue without barrier-stripping alcohols.

Betaine & Tremella Fuciformis (Snow Mushroom) Extract: Specialized osmolytes and hydrators that manage intracellular water balance and deliver intense, weightless moisture.

Broad-Spectrum Bio-Preservative & Sodium Phytate: Clean, broad-spectrum antimicrobial preservatives and chelating agents that perfectly stabilize the formula and prevent metal-ion oxidation without leaving sticky residues.

When to use

Apply 4-6 drops (up to a half dropper) every morning and/or evening to clean, dry skin.

The Perfect Pair

Start by cleansing with P01 WASH. After waiting 1 to 2 minutes for full absorption, follow with a hydration product like H03 PLUMP to lock in moisture and support the barrier. Finish your morning routine with an SPF 30 or above sunscreen.

Storage & Freshness

Keep tightly closed in a cool, dark place; refrigeration is recommended. Unlike pure L-Ascorbic Acid, 3-O-Ethyl Ascorbic Acid is highly resistant to oxidation, so this serum holds its potency far longer - but keeping it away from direct sunlight ensures maximum biological freshness.

The Golden Rule (Sun Protection)

While brightening agents and antioxidants powerfully shield the skin and fade existing dark spots, they are not a substitute for sunscreen. To protect your newly brightened skin and prevent hyperpigmentation from returning, finishing your morning routine with a broad-spectrum SPF 30+ is absolutely non-negotiable.
