Skincare Concerns: Dryness, Fine Lines, and Wrinkles

Formulation: Lightweight Serum

Highlighted Ingredients:
- 11kDa Hyaluronic Acid: By delivering hydration to skin's most vulnerable layer, 11kDa hyaluronic acid helps better retain moisture for improved resiliency, suppleness and bounce; the brand's smallest molecular size of hyaluronic acid, 11kda, penetrates to fortify skin.
- Adaptogenic Herbal Complex: A proprietary blend of adaptogensred ginseng root, holy basil and antioxidant-rich schisandra berry; within this formula, these adaptogens work synergistically to defend skin from stressors while renewing and resurfacing skin's texture for a smooth, radiant appearance.
