iS Clinical NeckPerfect Complex

The iS Clinical NeckPerfect Complex is a targeted treatment from iS Clinical formulated to firm, smooth, and restore elasticity to the neck, jawline, and décolleté. This complex combines gentle resurfacing acids, plant-based proteins, and advanced humectants to visibly address crepey texture, fine lines, and loss of definition in areas that tend to show aging faster than the face. The formula contains a light fragrance worth noting if you are sensitive to scent.

Key Benefits

Visibly firms and defines the neck and jawline Hydrolyzed quinoa and hydrolyzed rice protein work together to strengthen the skin's structural matrix, improving visible firmness and creating a more defined contour along the neck and jaw with consistent use.

Smooths crepey texture through gentle resurfacing A blend of fruit acids from bilberry, sugarcane, orange, lemon, and sugar maple, along with willow bark extract and salicylic acid, provides mild exfoliation to refine surface texture and reduce the appearance of fine lines without disrupting the skin barrier.

Delivers long-lasting hydration to thin, dehydrated skin Sodium hyaluronate draws moisture into the skin, while acacia senegal gum and hydrolyzed rhizobian gum create a flexible film that helps lock that hydration in, smoothing crepey areas and restoring a fuller, more resilient feel.

Calms and supports barrier repair Centella asiatica derivatives, including asiaticoside, asiatic acid, and madecassic acid, work alongside licorice root extract and green tea to soothe irritation, reinforce the skin barrier, and provide antioxidant defense against environmental stress.

Supports restored bounce and resilience over time Calcium pantothenate (provitamin B5) complements the hydrating gum complex to help skin recover its natural elasticity, reducing the look of sagging and looseness with regular use.

This treatment is ideal for anyone noticing loss of firmness, crepey texture, or fine lines on the neck, jawline, or décolleté, especially if your skincare routine has been focused on your face and your neck has quietly been catching up. Sun exposure, dehydration, and natural collagen loss all accelerate visible aging in these areas, and a standard moisturizer is rarely enough to address it.

The iS Clinical NeckPerfect Complex is suitable for all skin types, including sensitive skin. Its balanced pH of 3.9 keeps the fruit acid blend working effectively but gently, and the centella asiatica derivatives, licorice root extract, and green tea help maintain tolerance. If your skin is particularly reactive, a gradual introduction a few times per week is a smart starting point before moving to daily use.

Extend your application down to the upper chest and use slow, upward strokes rather than rubbing the product in. The neck and décolleté skin is thin and benefits from consistent, deliberate pressure in an upward direction. You may notice smoother texture within the first few weeks as the fruit acid and willow bark blend does its work, but the firming and lifting effects from the hydrolyzed proteins build gradually, so commit to at least six to eight weeks before evaluating results.

Apply: Smooth a small amount onto cleansed skin on the neck, jawline, and décolleté, using upward, lifting strokes.

Frequency: Use morning and evening. In the morning, follow with a moisturizer and a broad-spectrum SPF, as the fruit acid blend can increase sun sensitivity.
