IOPE Expert Vitamin C 25% Antioxidant Serum — 0.77 fl. oz., High-Purity L‑Ascorbic Acid for Brighter, Smoother Skin

This lightweight antioxidant serum is designed for visible improvement in clarity, radiance, and overall skin tone while offering mild exfoliation to smooth surface texture. The formula pairs a concentrated dose of high-purity vitamin C with a Penta Active antioxidant blend and 0.2% polyhydroxy acid (PHA), and it is housed in specialized packaging that protects the active ingredients from air and light to maintain potency.

How will a 25% vitamin C concentration affect my skin’s radiance?

A 25% concentration delivers a strong antioxidant effect that helps neutralize free radicals and supports the appearance of a brighter complexion. This potency can provide faster visible improvements in dullness and glow than lower concentrations when used correctly and consistently.

• High-purity L-ascorbic acid at 25% for intensive brightening potential.
• Penta Active antioxidant complex to amplify environmental protection.
• Lightweight texture allows fast absorption without greasy residue.

Will this serum help with uneven tone and texture?

Yes—IOPE’s combination of concentrated vitamin C and 0.2% PHA targets discoloration and roughness. Vitamin C supports a more even-looking tone while PHA provides gentle surface exfoliation to refine texture without irritation typical of stronger acids.

• Targets pigment and surface dullness for a more uniform complexion.
• 0.2% PHA offers mild exfoliation suitable for sensitive-prone skin.
• Regular use helps reduce the look of uneven texture and visible dullness.

How is the formula kept stable and effective?

The serum is packaged with a gas-release cap and a separate dropper to minimize air exposure, light, and contamination—common causes of vitamin C degradation. That protective system helps maintain the integrity and efficacy of the high-strength 25% formulation from first use to last.

• Gas-release cap reduces oxygen contact that can oxidize vitamin C.
• Separate dropper prevents repeated opening of the main container.
• Opaque or minimally transparent packaging limits light-induced breakdown.

How should I use this serum within my routine?

Apply a few drops to cleansed, dry skin once daily—typically in the morning to maximize daytime antioxidant protection or at night if preferred. Follow with moisturizer and broad-spectrum SPF in the morning; combine with complementary IOPE serums for targeted benefits.

• Use 2–3 drops on face and neck after cleansing and toning.
• Layer with moisturizer; always follow with SPF during daytime use.
• Can be paired with IOPE Expert PDRN Caffeine Shot for depuffing or Retinol RX 1% at separate times to avoid irritation.

Who is this for: This serum is intended for adults seeking a clinically oriented radiance booster to address dullness, uneven skin tone, and mild texture concerns. It suits users comfortable with active ingredients and those who want a protective antioxidant in their routine. Individuals with highly reactive or severely compromised skin should patch-test first or consult a skincare professional before using high-strength vitamin C products.
