Why You'll Love It

• Brightens & Evens Skin Tone: Vitamin C (ascorbic acid) has a powerful antioxidant action that helps neutralise the appearance of melanin build-up, working to visibly brighten the complexion and promote a more even, radiant glow.
• Targets Dark Spots & Uneven Pigmentation: Formulated to visibly minimise the look of freckles, dark spots, and areas of uneven pigmentation — helping to restore a clearer, more uniform skin tone over time.
• Supports Collagen & Skin Firmness: Vitamin C plays a key role in supporting the skin's natural collagen production process, helping to keep skin feeling firmer, plumper, and more resilient, with a visible reduction in the appearance of fine lines.
• Antioxidant Defence: Rich in antioxidants, this serum helps shield skin from the look of environmental stressors and daily oxidative exposure, supporting a more youthful, healthy appearance.
• Repairs & Revives Dull Skin: Breathe life back into tired, lacklustre skin — this essence absorbs quickly, leaving your complexion looking refreshed, luminous, and energised.

Frequently Asked Questions

Q: What does the RDQCTQ Vitamin C Brightening Face Serum do for my skin?

A: This Vitamin C face serum is designed to visibly brighten the complexion, reduce the appearance of dark spots, freckles, and uneven pigmentation, support collagen for firmer-looking skin, and revive dull or tired-looking skin with regular use.

Q: Can this Vitamin C serum be used on all skin types?

A: Yes — the lightweight oil-based formula is suitable for a range of skin types. As with any new skincare product, we recommend performing a patch test on a small area of skin before applying broadly, especially if you have sensitive skin.

Q: How long will it take to see visible results from the brightening serum?

A: Results vary by individual. Many users begin to notice a more even, radiant complexion with consistent daily use over several weeks. For best results, use as part of a complete skincare routine and always apply SPF during the day, as Vitamin C can increase skin's sensitivity to sun exposure.
