IOPE Expert Vitamin C 25% Antioxidant Serum — 25% Pure Vitamin C, Lightweight Brightening with 5-Antioxidant Complex (0.77 fl. oz.

IOPE Expert Vitamin C 25% Antioxidant Serum is a high-strength vitamin C treatment crafted to brighten skin, even tone, and smooth texture while preserving formula potency with protective packaging.

This lightweight serum combines 25% pure vitamin C with a five-antioxidant complex and a low-dose PHA to target dullness, uneven tone, and surface texture. Designed for daily use, the formula aims to reveal healthier-looking skin by supporting radiance and helping counteract environmental stressors. Its dual-component packaging—a gas-release cap and separate dropper—helps keep the concentrated vitamin C stable and effective from the first pump to the last.

How will this serum change my skin’s radiance?

The concentrated 25% pure vitamin C is formulated to boost visible brightness and impart a more luminous overall appearance. Complementary antioxidants help maintain the vitamin C’s activity so you get consistent brightening benefits with regular use.

• 25% high-purity vitamin C for strong brightening potential
• Penta Active 5-antioxidant complex to support antioxidant activity
• Lightweight texture that layers easily under moisturizers and makeup

Can it help improve uneven tone and texture?

Yes — the serum targets three core aspects of skin clarity: tone, radiance, and surface refinement. A gentle 0.2% PHA provides mild exfoliation to smooth texture while the antioxidants support a more even-looking complexion over time.

• 0.2% PHA for low-irritation surface renewal
• Antioxidant blend to help reduce the appearance of unevenness
• Formulated for regular daytime or nighttime application

Is the 25% vitamin C stable and easy to use?

Stability is addressed through IOSPE’s packaging design: a gas-release cap plus a separate dropper limit air exposure so the formula stays potent. The dropper dispenses controlled doses for consistent application without waste.

• Gas-release cap minimizes oxidation between uses
• Separate dropper for precise, hygienic application
• Opaque bottle helps protect actives from light

How does this serum fit into a daily skincare routine?

Use it after cleansing and before moisturizer; in the morning it can pair with sunscreen, and at night it layers well under richer treatments. For a targeted regimen, combine with complementary IOPE products for depuffing and retinol-based renewal.

• Apply a few drops to face and neck on clean skin
• Morning use should be followed by broad-spectrum SPF
• Compatible with IOPE Expert PDRN Caffeine Shot and Retinol RX routines

Who this is for: IOPE Expert Vitamin C 25% Antioxidant Serum suits anyone seeking a potent brightening step in their skincare ritual — particularly those wanting a concentrated vitamin C treatment that addresses dullness, uneven tone, and texture while prioritizing formula stability. It is formulated for people comfortable using strong vitamin C serums; those with very sensitive skin should patch-test and introduce gradually.
