C20 GUARD is our flawless execution of skincare's most clinically proven anti-aging combination. By synergizing 20% pure L-Ascorbic Acid with precise clinical doses of Botanical Ferulic Acid, Sunflower-derived Vitamin E, and 1% Phloretin, this formula creates an impenetrable antioxidant shield against free radicals, UV-induced damage, and severe photo-aging. To counterbalance the intensity of this trinity, we cushioned the matrix with Allantoin and Snow Mushroom Extract. Driven by our green-chemistry transit system, this clinical-strength dose penetrates efficiently, delivering maximum environmental defense without leaving a single trace of sticky or greasy film.

The C+E+Ferulic combination is notoriously difficult to formulate elegantly. To keep the ingredients stable, legacy clinical brands and budget dupes rely heavily on 1% or higher doses of cheap synthetic Vitamin E and heavy, barrier-clogging solvents. This results in a sticky, tacky finish that famously carries the offensive "hot dog water" scent, suffocates the pores, and pills (rolls up into tiny flakes or balls) under makeup. These heavy, outdated formulas also tend to trigger severe breakouts in combination and oily skin types.

We Do Things Differently

We engineer C20 GUARD to deliver the gold standard of anti-aging with flawless sensory elegance. By utilizing pure Botanical Ferulic Acid and Purified Sunflower Vitamin E, we eliminated the chemical odors associated with traditional C+E formulas. Relying on an advanced green-chemistry transit system of DMI and Propanediol, we completely bypass the need for sticky glycols and heavy synthetic lipids. The result is an odorless, clinical-strength antioxidant shield 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 the most aggressive hyperpigmentation correction and free-radical neutralization possible.

The Antioxidant Synergizers

0.5% Botanical Ferulic Acid & 0.5% Purified Sunflower Vitamin E & 1% Phloretin: Natural Vitamin E is more than twice as biologically active as synthetic alternatives. This 0.5% dose, paired with a 1% Phloretin polyphenol, delivers profound antioxidant protection - perfectly synergizing with the clinical-standard 0.5% Ferulic Acid to multiply and stabilize the photoprotective power of Vitamin C (the complete CEF + Phloretin network).

The Recovery Complex

0.4% Allantoin: Utilized an aggressive 0.4% clinical-grade payload to rapidly down-regulate the contact redness caused by environmental stress.

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. After waiting 1 to 2 minutes for full absorption, use a hydration product like H03 PLUMP to lock in hydration and protect the barrier. Follow 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.
