skinbetter science InterFuse Intensive Treatment LINES is the most unique product in the skinbetter science lineup — a physician-developed topical line treatment containing injectable-grade Hyaluronic Acid (the same grade used in dermal fillers) in a delivery system that drives it into fine lines and wrinkles for visible, immediate smoothing. It is the exception to standard regimen layering order: always applied first, directly to lines, before other serums and treatment products.

Injectable-grade Hyaluronic Acid — the highest purity and molecular specification of HA — is delivered directly into the folds of fine lines and wrinkles via the InterFuse technology, where it instantly fills and plumps lines from within for visible smoothing. Unlike surface-level HA moisturizers that hydrate the skin above lines, InterFuse specifically targets the line itself. Peptide Complex provides collagen-stimulating signals at the dermal level for long-term line softening beyond the immediate volumizing effect. Niacinamide and hydrating actives support the surrounding skin quality. The 5ml size delivers consistent, controlled dosing for targeted line application morning and evening.

Apply directly to specific lines and wrinkles before other skincare products, morning and evening. Paraben-free, fragrance-free. Available at Beauty Riche — authorized skinbetter science retailer with same-day shipping.
