Celestial Nightly Skin Repair Oil Serum for Firming, Hydrating and Restoring + Kakadu Plum

Kakadu plum delivers a concentrated source of vitamin C to support natural collagen production, while macadamia oil provides fatty acids that help reinforce the skin barrier and encourage cell regeneration. Baobab oil rounds out the formula by sealing in moisture and improving the appearance of elasticity. Well-suited for dry, combination, and normal skin types, particularly those concerned with loss of firmness or a compromised skin barrier.
