ITK Brightening Vitamin Serum — 1 oz facial vitamin C & niacinamide for brighter, smoother skin (fragrance-free, vegan)

ITK Brightening Vitamin Serum is a 1 oz facial serum blending vitamin C and niacinamide to brighten skin tone and support smoother-looking texture.

This lightweight, dermatologist-tested formula from ITK combines antioxidant-rich vitamin C with niacinamide in a vegan, sulfate- and paraben-free base. Designed for daily use, it targets uneven tone, dullness, and signs of surface aging while fitting into morning or evening routines. The fragrance-free formula is built to be gentle on a range of skin types and layers easily under moisturizers and SPF.

How quickly will I notice brighter, more even skin?

Visible improvements in tone and radiance generally appear with consistent use over several weeks. Vitamin C works to reduce the look of discoloration while niacinamide helps regulate tone and texture; together they support a gradual brightening effect without harsh irritation.

• Use once or twice daily after cleansing and before moisturizer.
• Expect incremental changes in 4–8 weeks with steady application.
• Best paired with daily SPF in the morning to protect results.

Will this serum suit sensitive or reactive skin?

ITK formulated the serum without sulfates, parabens, or synthetic fragrances to minimize common irritants. Although dermatologist-tested and designed to be gentle, skin sensitivity varies—start with a patch test and introduce the serum gradually to gauge tolerance.

• Fragrance-free and vegan base reduces potential triggers.
• Begin with every-other-day use if you have reactive skin.
• Consult a dermatologist if you have known ingredient allergies.

How should I incorporate ITK Brightening Vitamin Serum into my routine?

Apply a few drops to clean, dry skin after toning and before heavier creams. In morning routines it layers well under SPF; at night it complements hydrating moisturizers and targeted treatments for fine lines or uneven tone.

• Morning: cleanse, serum, moisturizer, SPF.
• Evening: cleanse, serum, treatment (if used), moisturizer.
• Store away from direct sunlight to preserve formula stability.

What makes ITK’s formula different from other vitamin serums?

ITK balances vitamin C and niacinamide in a vegan, dermatologist-tested base that avoids common harsh additives. The focus is steady results with gentle daily use rather than high-concentration, aggressive treatments that can increase sensitivity.

• Antioxidant vitamin C for brightness and surface clarity.
• Niacinamide to help refine texture and even skin tone.
• Free from sulfates, parabens, and synthetic fragrances.

Who this is for: ITK Brightening Vitamin Serum is intended for anyone seeking a gentle, daily brightening step—especially those with dullness, mild discoloration, or early signs of texture changes who prefer fragrance-free, dermatologist-tested, vegan skincare. If you have severe skin conditions or active irritation, check with a healthcare professional before using.
