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.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails class=\"nf-q\"\u003e\u003csummary\u003e\u003ch3\u003eWhat makes it different\u003c\/h3\u003e\u003c\/summary\u003e\u003cdiv\u003e\n\u003cp\u003eDaily 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.\u003c\/p\u003e\n\u003ch4\u003eWe Do Things Differently\u003c\/h4\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003cdetails class=\"nf-q\"\u003e\u003csummary\u003e\u003ch3\u003eKey actives\u003c\/h3\u003e\u003c\/summary\u003e\u003cdiv\u003e\n\u003ch4\u003eThe Core Active\u003c\/h4\u003e\n\u003cp\u003e20% Pure L-Ascorbic Acid: Formulated at the 20% limit to deliver maximum-strength foundational brightening and collagen support.\u003c\/p\u003e\n\u003ch4\u003eThe Antioxidant Synergizers\u003c\/h4\u003e\n\u003cp\u003e0.5% Botanical Ferulic Acid: The clinical-standard 0.5% Ferulic Acid reinforces and stabilizes the antioxidant network, doubling the photoprotective power of the Vitamin C.\u003c\/p\u003e\n\u003ch4\u003eThe Resurfacing Acid\u003c\/h4\u003e\n\u003cp\u003e5% 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.\u003c\/p\u003e\n\u003ch4\u003eThe Recovery Complex\u003c\/h4\u003e\n\u003cp\u003e0.5% Panthenol, 0.4% Allantoin \u0026amp;
