IOPE Expert Vitamin C 40% Concentrate Cream — 0.67 fl oz Water-Free High-Potency Brightening + Resveratrol

This concentrated, waterless formula delivers a 40% dose of pure vitamin C in a lightweight cream that melts into skin while remaining stable thanks to a triple-layer aluminum tube designed to block light and air. Enhanced with supportive actives like resveratrol and NMN, the cream focuses on brightness, texture, and resilience for a refreshed-looking complexion.

How does this 40% vitamin C concentrate target dark spots and uneven tone?

The product uses a high-purity vitamin C concentration to promote a more radiant, uniform complexion while complementary ingredients help support skin structure. It is formulated to deliver antioxidant benefits directly to the skin without dilution from water.

• 40% pure vitamin C for intensive brightening potential.
• Resveratrol to support firmness and antioxidant protection.
• NMN to boost surface vitality and improve skin radiance.
• Water-free base ensures high active potency at application.

Is a 40% vitamin C concentrate safe and how can I avoid irritation?

A high-strength vitamin C increases potency and sensitivity risk, so gradual introduction and pairing with hydrating, soothing steps helps tolerance. Start with small amounts and monitor skin reaction; discontinue if persistent irritation occurs.

• Begin with a pea-sized amount once every other night, then increase frequency.
• Apply after hydrating serums (e.g., XMD Stem III Serum) to reduce potential dryness.
• Use sunscreen during daytime to protect newly revealed skin layers.
• Avoid simultaneous use with other strong actives until tolerance is established.

How should I incorporate this concentrate into my skincare routine?

Use the cream as a finishing treatment in the evening or as directed, after serums and before heavier occlusives. For a professional-level result, combine with recommended supporting products to maximize smoothing and brightening effects.

• Cleanse and apply hydrating serum (e.g., XMD Stem III Serum) first.
• Apply retinoid products on alternate nights if using Retinol RX 2% as advised.
• Finish with the Vitamin C 40% Concentrate Cream to lock in actives.
• Always follow with SPF in the morning routine.

Why is the water-free packaging important for vitamin C stability?

Vitamin C degrades quickly when exposed to water, light, and air; a water-free formula housed in a triple-layer aluminum tube limits exposure and preserves potency until application. The packaging helps maintain the actives' integrity so the product performs as intended.

• Triple-layer aluminum tube blocks light and air to reduce oxidation.
• Water-free base prevents premature breakdown of pure vitamin C.
• Compact 0.67 fl. oz. size reduces product waste and exposure.
• Designed for direct, stable delivery at high concentration.

Who is this for: This concentrate suits those seeking a powerful topical vitamin C treatment to address persistent dark spots, dullness, and early texture changes. Ideal for adults comfortable with high-strength actives and willing to integrate the cream into a cautious routine—begin slowly, pair with hydrating and protective steps, and consult a dermatologist if you have highly reactive or compromised skin.
