Skin 2.0 Vitamin C + Collagen Day & Retinol Night Serum Duo

Skin 2.0 is a dual-serum Korean skincare system pairing retinol & vitamin E (night) with vitamin C & collagen (day). The day serum delivers vitamin C with collagen and vitamin E for brightening and hydration; the night serum adds retinol for anti-aging support. Positioned as dermatologist-tested, vegan, and clean beauty, it targets visible lines, firmness, and radiance. Pack of 2 (3.8 oz total) at ~$4.79/oz with Subscribe & Save undercuts premium vitamin-C serums but lacks transparency on vitamin-C form and concentration—critical for efficacy. Suits mixed skin types seeking a gentle, hydrating C + retinol routine rather than high-potency L-ascorbic acid. Community feedback is positive but limited; no major red flags on oxidation or irritation.
