Phase 2 regeneration active. Bioactive peptides signal the skin to produce its own collagen from within — targeting firmness loss, fine lines, and weakened skin structure after Phase 1 correction. Where the Aichun set rebuilds hydration and brightness, this serum works at the structural layer — restoring elasticity and skin density over time. 30ml amber dropper. Formulated for melanin-rich African skin. Pay after delivery.
