The neck and décolleté are among the first areas to show visible signs of aging. Unlike facial skin, these regions have fewer oil glands and thinner skin, making them more prone to dehydration and collagen loss. As collagen and elastin production naturally slow with age, the skin loses firmness—leading to wrinkles, sagging, and creases. Sun exposure (often overlooked on the neck and chest) accelerates this breakdown, while lifestyle factors like smoking, poor nutrition, dehydration, and “tech neck” from looking down at devices can further deepen lines.
What You Can Do
Consistency is key. Treat your neck and chest with the same care as your face. Gentle cleansing, regular exfoliation, and daily SPF make a visible difference over time.
At-Home Care
Incorporate a nourishing routine that includes peptide-rich serums, vitamin C for brightening, and hydrating ingredients such as hyaluronic acid and ceramides. Apply products in upward motions to encourage circulation and absorption. Layer in formulas that combine advanced peptide complexes, antioxidant-rich botanicals, and replenishing hydrators. For example, St. Croix Products’ Peptide Blast Day Cream, Peptide Blast Night Cream, or Lift & Firm Serum feature powerful peptide complexes and ceramides to support firmness, elasticity, and resilience. St. Croix formulations emphasize high-performance peptides, retinoids, ceramides, and botanical extracts designed to visibly rejuvenate and strengthen the neck and décolleté.
Suggested Ingredients
Look for ingredients that promote renewal and protection: retinol or bakuchiol (a natural alternative) to boost collagen, niacinamide to even tone, and antioxidants such as green tea or coenzyme Q10 to combat free radicals. Peptide complexes like Matrixyl 3000™, which St. Croix Products utilizes, help restore a smoother, firmer appearance. Add stable vitamin C for brightening and collagen support, ceramides to lock in hydration, and soothing botanical extracts and oils such as green tea or rosehip to calm and protect.
Professional and Prolonged Results
Professional treatments such as microneedling, red light therapy, or gentle peels can complement your at-home skincare routine, but daily care is what sustains long-term improvement.
Things to Avoid
Avoid harsh scrubs, tanning, and excessive sun exposure. Protect your skin barrier by steering clear of irritants and maintaining hydration inside and out. To prevent “tech neck,” hold your phone at eye level, and support your skin from within (ideally with guidance from your doctor or dietitian) through a balanced diet rich in antioxidants, healthy fats, and plenty of water.
My best advice for the neck and décolleté is daily moisturization and preventing sun damage.
