The Ordinary Vitamin C Radiance Serum — Multi-Antioxidant Brightening & Protection, 1 Fl Oz

The Ordinary Multi-Antioxidant Radiance Serum is a daily Vitamin C–forward antioxidant serum designed to brighten skin, strengthen defenses against environmental stressors, and improve overall radiance.

Everyday exposure to pollution, UV rays, and other environmental aggressors can leave skin looking dull and uneven. This lightweight serum mixes stabilized forms of Vitamin C with a multi-technology antioxidant complex to target discoloration, sharpen skin tone, and support a healthier surface appearance without heavy silicones or oils. It’s formulated for routine morning and evening use as part of a layered skincare regimen.

How does this serum help brighten and even skin tone?

The formula combines a stabilized Vitamin C derivative with complementary antioxidants to reduce the look of dullness and improve luminosity. Regular application helps fade the appearance of dark spots and gives skin a visibly clearer, more uniform finish.

• Stabilized Vitamin C targets uneven pigmentation and promotes brighter skin over time
• Additional antioxidants neutralize surface free radicals that can cause discoloration
• Lightweight texture absorbs quickly to layer under moisturizers or SPF

Can this serum protect skin from environmental stressors?

The serum’s antioxidant blend is intended to support the skin’s resilience against daily environmental challenges like pollution and UV-induced oxidative stress. It helps reduce the visible impact these stressors have on tone and texture when used consistently.

• Multiple antioxidant technologies target different pathways of oxidative damage
• Daily application contributes to barrier support and surface defense
• Recommended to follow with a broad-spectrum sunscreen in daytime routines

What results should I expect and how quickly?

Visible improvements—such as increased radiance and a more even tone—can appear within weeks, while more persistent discoloration may take longer to fade. The serum also works to smooth texture and reduce the appearance of fine lines with continued use.

• Noticeable boost in glow and luminosity in a few weeks for many users
• Smoother, softer skin texture with ongoing applications
• Consistent morning/evening use accelerates cumulative benefits

How should I use this product safely with other actives?

Apply a few drops to clean, dry skin each morning and evening. Avoid mixing directly with niacinamide or copper peptides in the same routine; if using those ingredients, alternate routines or layer with time between applications. Always patch test new products and use sunscreen during daytime.

• Apply on clean, dry skin—follow with moisturizer and daytime SPF
• Do not combine directly with niacinamide or copper peptides
• Patch test before first use and discontinue if irritation occurs

Who is this for: Ideal for people seeking a straightforward antioxidant step to enhance brightness, refine uneven tone, and support skin against daily environmental aggressors. Suitable for most skin types looking for a non-greasy, layering-friendly serum; avoid if you react to Vitamin C derivatives or active antioxidant complexes. For best results, incorporate into a complete routine that includes sun protection during the day.
