Obagi Medical Elastiderm Neck And Decollete Concentrate is a neck lifting concentrate formulated with Retinoid and Alpha-Arbutin to address visible signs of aging on the neck and décolleté. Suitable for normal-to-dry, normal-to-oily, and combination skin types, this dermatologist-tested formula is designed for concerns related to aging and sagging skin, fine lines and wrinkles, dehydrated skin, and skin discoloration. The concentrate combines advanced ingredient technologies to help improve the appearance of skin elasticity and support firmer-looking, more resilient skin. This powerful triple-threat formula features patented Bi-Mineral Contour Complex, a smoothing Retinoid, and brightening Alpha-Arbutin. Together, these ingredients target visible signs of skin aging while helping improve the appearance of the neck and upper chest area. The concentrate visibly improves horizontal neck lines, fine lines, skin sagging, and crepiness, with noticeable results in as little as eight weeks and full results at twelve weeks. Bi-Mineral Contour Complex promotes the necessary stages of healthy elastin to help reduce the appearance of sagging, horizontal lines, and laxity on the neck and upper chest. The formula also contains Retinoid, which helps decrease the appearance of fine lines, wrinkles, and the overall appearance of skin aging while supporting a smoother-looking skin texture. Alpha-Arbutin complements the formula with brightening benefits for a more even-looking appearance. Clinical study results demonstrated visible improvements after eight weeks of use. Results showed visible improvement in horizontal neck lines and fine lines for 97% of participants, visible improvement in skin sagging for 81% of participants, and visible improvement in neck crepiness for 100% of participants. Elastiderm Neck and Décolleté Concentrate helps promote firmer-looking, smoother, and more resilient skin on the neck and décolleté.
