Power-C Firming & Brightening Serum Capsules

Our airtight, biodegradable single-use capsules exist to solve vitamin C’s most fundamental problem: oxidation. In a traditional serum, L-ascorbic acid is suspended in water and repeatedly exposed to air and light, three factors that degrade its potency over time.

Power-C Capsules sidestep the variables that cause failure. Each capsule is hermetically sealed, with no air, light, or water. The first and last capsules deliver an identical full-strength result. That consistency is not possible in a traditional formula.

For many people, yes. However, 20% L-ascorbic acid is a potent concentration, so those with sensitive skin may benefit from introducing it gradually. The irritation commonly associated with vitamin C is often linked to the highly acidic environment required by traditional, low-pH water-based formulas. In Power-C, the active is not suspended in water and is therefore less acidic.

Some effects are immediate. The blurring base provides a filter-like finish that smooths skin’s appearance. Brightness emerges within the first several weeks as the L-ascorbic acid inhibits tyrosinase, the enzyme responsible for melanin overproduction. As cellular collagen stimulation and long-term antioxidant defense take hold, improvements in firmness, skin texture, fine lines, and overall tone continue to build.

Yes, but not in the same application. Power-C is a high-potency serum, and layering it with retinol, AHAs, or BHAs can increase the risk of irritation, especially as skin adjusts. A more balanced approach is to use Power-C on its own at first, then alternate nightly treatments once skin has acclimated. For example, use Power-C one night and retinol or exfoliating acids on another, adjusting frequency based on skin’s tolerance. Eventually, you may use vitamin C and retinol on the same day, applying vitamin C in the morning for protection, and retinol at night for regeneration when skin is in restoration mode.

L-ascorbic acid is the pure, direct form of vitamin C and the only form that skin cells can use without conversion. Many vitamin C products use derivatives (ascorbyl glucoside, sodium ascorbyl phosphate, magnesium ascorbyl phosphate) because they are more stable in water-based formulas and gentler on skin. Derivatives require conversion into L-ascorbic acid, reducing concentration and delivery speed.

If you have tried a vitamin C serum before and been disappointed, Power-C is the reason to try again. It combines a potent vitamin C active with restorative and protective ingredients, all housed in an integrity-preserving capsule. This approach helps address the stability, oxidation, and sensitivity concerns associated with conventional vitamin C serums.

Power-C is not a spot treatment; it is applied across the full face to deliver systemic brightening, antioxidant defense, and firming benefits. The capsule delivery reduces degradation and ensures the 20% L-ascorbic acid reaches skin at full potency, which an aqueous formula exposed to air and light cannot reliably guarantee.

No. Each capsule is made from a 100% vegetal, biodegradable shell, offering a plastic-free alternative that protects the formula until use.
