Alastin Restorative Neck Complex with TriHex Technology® is a physician-developed, targeted anti-aging treatment specifically formulated for the neck and décolleté area — skin that ages differently than the face due to greater sun exposure, a thinner epidermal layer, and less active sebaceous gland activity that accelerates crepiness, laxity, and discoloration. It is the only Alastin formula specifically optimized for neck-area aging concerns.TriHex Technology® — the patented peptide complex that clears damaged elastin and collagen and supports new matrix protein production — is particularly impactful on neck skin, where elastin degradation is the primary driver of the visible crepiness, horizontal neck lines, and loss of definition that characterize neck aging. It visibly improves crepey texture, skin laxity, and discoloration on the neck and décolleté with consistent use. Silver Mushroom provides intense hydration to the typically drier neck skin. Niacinamide addresses the uneven pigmentation common on sun-damaged neck and chest skin. Hydroxymethoxyphenyl Decanone supports natural hyaluronic acid production. The lightweight serum-cream texture absorbs rapidly and is designed for upward application with lifting strokes to complement the lifting direction of the anti-aging actives.Apply one pump and smooth upward from the chest to the jaw morning and evening. Non-comedogenic, fragrance-free. Available at Beauty Riche — authorized Alastin retailer with same-day shipping.
