Dr H Marine Collagen Renewal Serum is a fast-absorbing anti-aging treatment that helps visibly firm skin, smooth fine lines, and target wrinkles. Key actives include Vitamin C (Sodium Ascorbyl Phosphate) to brighten and reduce dark spots, Collagen Amino Acids to support skin firmness and bounce, and Vitamin E to protect and nourish. Lightweight serum absorbs quickly and layers easily into morning and evening routines. Apply a few drops to clean, slightly damp skin on face and neck, allow to absorb, then follow with moisturizer and morning SPF. Ideal for normal to dry skin seeking a concentrated firming and smoothing serum. Results may vary; some users notice improved hydration and texture within weeks with consistent use. For external use only, avoid contact with eyes and keep out of reach of children.
