Rbfy. Core Vita Radiance Ampoule — 17% Vitamin C Face Serum, Brightening & Dark Spot Reduction (1.01 fl oz)

Rbfy Core Vita Radiance Ampoule is a concentrated 17% pure Vitamin C face serum designed to brighten skin, reduce dark spots, and support visible anti-aging benefits.

This lightweight ampoule blends pure ascorbic acid and 3-O-ethyl ascorbic acid with Ferulic Acid and Vitamin E to deliver antioxidant protection and targeted brightening. Dermatologically tested and fragrance-free, it’s formulated to help even skin tone, minimize post-acne marks and enhance radiance while remaining suitable for a mindful skincare routine. Because pure Vitamin C is active and sensitive, the formula requires careful storage and timely use to stay potent.

How will this serum improve dull or uneven skin tone?

The combination of 17% pure Vitamin C and a stabilized derivative works to interrupt melanin overproduction and support cellular turnover, helping skin look clearer and more luminous. Antioxidants in the formula protect against environmental stress that accelerates dullness, so improvements build with consistent application.

• 17% pure ascorbic acid for direct brightening action
• 3-O-ethyl ascorbic acid for stability and continued effect
• Ferulic Acid and Vitamin E to boost antioxidant power
• Fragrance-free to reduce irritation risk

Can this product help reduce dark spots and hyperpigmentation?

The ampoule targets discoloration by delivering potent Vitamin C forms that help fade post-inflammatory marks and sun-induced pigmentation over time. Regular nightly or morning use with sunscreen will give the best chance of visible reduction in spots while preventing further darkening.

• Targets post-acne marks and sunspots with brightening actives
• Supports gradual fading rather than overnight removal
• Works best alongside daily sun protection
• Visible changes typically appear with weeks of consistent use

Is this serum suitable for sensitive or aging skin?

Although potent, the formulation avoids added fragrance and includes Vitamin E to soothe and stabilize Vitamin C, making it approachable for many skin types when introduced slowly. Patch testing and starting with every-other-day application helps those with sensitivity adapt while assessing tolerance.

• Fragrance-free to limit irritation triggers
• Vitamin E offers supportive antioxidant and calming properties
• Begin with small amounts or less frequent use to acclimate skin
• Dermatologically tested for broader skin compatibility

How should I store and use this ampoule to keep it effective?

Pure Vitamin C oxidizes when exposed to light, heat and air, so store the bottle upright in a cool, shaded spot and use within two months after opening for optimal potency. Expect slight color changes or natural "hiss" sounds on opening; these are normal signs of an active Vitamin C formula and not indications of spoilage.

• Store upright in a cool, shaded area away from direct sunlight
• Use within two months after opening for best results
• Apply to clean skin before moisturizer; follow with sunscreen in daytime
• Keep the cap tightly closed to limit oxygen exposure

Who this is for: Rbfy Core Vita Radiance Ampoule is suited for people looking to brighten dull skin, fade discoloration and support anti-aging care with a high-strength Vitamin C formula. It’s a good fit for those comfortable introducing active treatments into their routine—especially anyone willing to follow storage and usage guidance for pure Vitamin C. If you have very reactive skin, perform a patch test and build up use gradually; for everyone else, pair with broad-spectrum sunscreen for daytime protection and consistent results.
