The skin around the eye is the thinnest, most fragile skin on the face — losing collagen, elastin, and hyaluronic acid faster than any other area, and showing the earliest visible signs of aging in the form of fine lines, crow's feet, dark circles, and puffiness. SkinMedica TNS Eye Repair is a physician-formulated treatment that addresses all four of these concerns simultaneously, delivering growth factors, antioxidants, peptides, and hydrating agents in a specialized eye-area formula.TNS (Tissue Nutrient Solution) is SkinMedica's proprietary growth factor complex derived from a fibroblast-conditioned media that contains a comprehensive profile of human growth factors, cytokines, and matrix proteins — the same signaling molecules that direct skin repair and collagen remodeling in the dermis. Applied topically, TNS stimulates fibroblast activity to improve skin firmness, smooth fine lines, and enhance the overall resilience of the delicate eye-area skin. Palmitoyl Oligopeptide and Palmitoyl Tetrapeptide-7 (Matrixyl 3000) provide additional collagen-stimulating peptide activity through a complementary signaling pathway. Caffeine provides vasoconstriction to reduce dark circles and puffiness by temporarily improving microcirculation and reducing fluid accumulation under the eyes. Vitamin C and antioxidant complex protect against photoaging and free radical damage.Apply a small amount to the orbital bone area morning and evening using the ring finger. Avoid direct contact with eyes. Suitable for all skin types. Available at Beauty Riche — authorized SkinMedica retailer with same-day shipping.
