ITK Brightening Vitamin Serum — 1 oz Facial Vitamin C + Niacinamide, Vegan, Fragrance-Free Radiance Booster

ITK Brightening Vitamin Serum is a 1 oz facial serum that blends vitamin C and niacinamide to brighten complexion and support healthier-looking skin.

This lightweight, vegan-friendly serum from ITK is formulated without sulfates, synthetic fragrances, or parabens and has been dermatologist-tested for compatibility with a wide range of skin types. Designed to slip easily into morning or evening routines, it aims to help even skin tone, reduce the look of discoloration, and leave skin with a fresher, more radiant appearance when used consistently alongside your chosen moisturizer and sunscreen.

How does this serum fit into a daily skincare routine?

Use ITK Brightening Vitamin Serum after cleansing and toning, before heavier creams or oils. A few drops applied to slightly damp skin allow active ingredients to absorb efficiently so subsequent products layer well.

• Apply 3–4 drops to face and neck morning and/or night.
• Follow with a moisturizer and broad-spectrum sunscreen in the morning.
• Can be layered under serums with hyaluronic acid or peptides for added hydration.

What ingredients are responsible for brightening and skin tone improvement?

The formula centers on vitamin C and niacinamide—two well-known, non-prescription actives for promoting a more even-looking complexion. ITK combines these with a base of skin-friendly, plant-derived components and excludes harsh additives to keep the texture gentle yet effective.

• Vitamin C: supports visible radiance and helps reduce the look of dark spots.
• Niacinamide: helps improve skin texture and overall tone consistency.
• Vegan, fragrance-free base: minimizes irritation potential for sensitive skin.

Is this serum suitable for sensitive or combination skin?

ITK Brightening Vitamin Serum is dermatologist-tested and formulated without common irritants like synthetic fragrances and sulfates, making it suitable for many sensitive or combination skin profiles. As with any active product, start with a patch test and introduce it slowly to monitor tolerance.

• Dermatologist-tested to support broad skin compatibility.
• Free of parabens and harsh sulfates to reduce irritation risk.
• Begin alternate-day use if you have reactive skin, then increase frequency as tolerated.

Who is this for: ITK Brightening Vitamin Serum is aimed at women looking to reduce the appearance of uneven tone, dark spots, or the early visible signs of aging without introducing synthetic fragrances or parabens. It's a practical option for those who want a daily, vegan-friendly serum to pair with a moisturizing and sun-protection routine, suitable for most skin types when introduced carefully.
