C20 RENEW is the ultimate solution for consumers who want high-potency Vitamin C without the chronic dryness or barrier degradation typically caused by low-pH acids. Delivering a clinical 20% payload of pure L-Ascorbic Acid, this formula neutralizes free radicals and aggressively brightens dull skin. To keep the skin calm through the dual-acid load, we cushioned the matrix with Panthenol (B5), Allantoin, and Yeast Beta-Glucan to actively soothe and support recovery on contact. Driven by our green-chemistry transit system, this clinical-strength dose penetrates efficiently, delivering intensive brightening and smoothing without leaving a single trace of sticky or greasy film.

Daily use of a 20% clinical acid naturally stresses the skin. To survive it, consumers are usually forced to layer heavy, waxy "barrier-repair creams" over their serum, which suffocates the pores and leaves skin looking congested. Legacy brands attempt to solve this by trapping their Vitamin C in thick, waterless silicone or heavy mineral oils. This results in a heavy, tacky finish that carries the offensive "hot dog water" scent, suffocates the skin, and pills (rolls up into tiny flakes or balls) under makeup.

We Do Things Differently

We engineer C20 RENEW for effective resurfacing and flawless sensory elegance. Relying on an advanced green-chemistry transit system of DMI and Propanediol, we completely bypass the need for gritty silicones and heavy occlusive waxes. By pairing dual exfoliating acids with a soothing, weightless recovery base, we created a clinical-strength 20% acid 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

20% Pure L-Ascorbic Acid: Formulated at the 20% limit to deliver maximum-strength foundational brightening and collagen support.

The Antioxidant Synergizers

0.5% Botanical Ferulic Acid: The clinical-standard 0.5% Ferulic Acid reinforces and stabilizes the antioxidant network, doubling the photoprotective power of the Vitamin C.

The Resurfacing Acid

5% Mandelic Acid: A gentle, large-molecule AHA dosed at 5% to accelerate cellular turnover, smooth rough texture, and fade pigment evenly-without the sting of smaller acids, making it ideal to pair with high-strength Vitamin C.

The Recovery Complex

0.5% Panthenol, 0.4% Allantoin & 0.1% Yeast Beta-Glucan: Panthenol, Allantoin, and Yeast Beta-Glucan work synergistically to soothe the skin, calm the stinging of low-pH acids on contact, and accelerate tissue repair through the dual-acid load.

The Advanced Transit & Base Matrix

Propanediol & Dimethyl Isosorbide (DMI): A targeted green-chemistry solvent network that drives the massive active 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 to clean, dry skin. (Note: Because this is a maximum-strength 20% acid, a slight, temporary tingling sensation upon application is a normal sign of the active acid at work).

The Perfect Pair

Start your morning off by cleansing your skin with a face wash like P01 WASH. Because C20 RENEW delivers a strong dual-acid treatment, follow with a hydrating serum such as H03 PLUMP to replenish moisture. Wait 1 to 2 minutes for the formula to absorb, and finish with an SPF 30 or above sunscreen.

Storage & Freshness

Keep tightly closed in a cool, dark place. For maximum freshness and to protect the active acid from premature oxidation, refrigeration is highly recommended.

(Note: Pure L-Ascorbic Acid naturally oxidizes over time, especially when exposed to air. A slight champagne tint is normal, but discard if the serum turns dark brown).

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.
