Serenity Hue Lab Twist™ 20% THD Vitamin C + Astaxanthin Advanced Brightening Antioxidant Serum | 30ml

High-strength vitamin C without the sensitivity. Lab Twist delivers 20% bioavailable vitamin C in a lightweight, non-irritating formula—perfect for brightening dull, tired skin while building collagen. Unlike water-based vitamin C serums that degrade within weeks, ours remains stable for months. You'll see radiance lifting within 3-5 days and real skin texture changes by week 4. This is what £70 luxury brands sell. At £19.99, it's an absolute steal. Ideal for morning use under SPF. Compatible with most routines, though skip retinol on vitamin C nights.
