iS Clinical NeckPerfect Complex | Firming & Lifting Neck & Décolleté Treatment

The neck ages faster than the face and is treated far less often. Skin here is thinner, has fewer sebaceous glands, moves constantly and is almost never included in a daily skincare routine until the changes are already visible. NeckPerfect Complex was formulated specifically for this area, combining natural fruit acids, plant-based firming proteins and Hyaluronic Acid to visibly lift, firm, smooth and sculpt the neck, jawline and décolleté with continued use.

Clinical results: 83% of subjects saw improved elasticity. 85% noticed enhanced firmness and sculpting. 87% experienced smoother skin tone and texture.

Who is NeckPerfect Complex best for?

• Visible skin laxity, crepiness and wrinkles on the neck and jawline
• Those wanting to address jowling and loss of jaw definition non-invasively
• Those on GLP-1 medications experiencing accelerated neck skin laxity during weight loss
• Those wanting to complement or extend the results of radiofrequency, HIFU or skin tightening treatments on the neck
• Post-injectable patients wanting to maintain neck and jawline results between appointments
• Those noticing the neck ageing faster than the face

Key ingredients and why they matter

• Mixed Fruit Acids (AHA/BHA blend from Bilberry, Sugarcane, Orange, Lemon and Sugar Maple): Gently exfoliate and resurface neck skin while improving absorption of the firming actives that follow
• Acacia Senegal Gum: A sustainably sourced botanical firming agent that provides an immediate visible tightening and smoothing effect on application alongside longer-term structural improvement
• Hydrolyzed Quinoa and Hydrolyzed Rice Protein: Strengthen the skin's structural matrix for improved firmness and a more defined neck and jaw contour over time
• Sodium Hyaluronate: Deeply hydrates and plumps the thin, dehydrated skin of the neck and décolleté
• Centella Asiatica, Licorice Root and Green Tea: Soothe, brighten and protect against the oxidative stress that accelerates neck ageing

How we use NeckPerfect Complex at Face for Soul

As a pharmacist prescriber specialising in skin health, NeckPerfect Complex is one of the most consistent recommendations I make to patients whose facial skincare routine is already well-established but who have not addressed the neck. The neck is one of the first areas where GLP-1-related skin laxity becomes visible, and one of the areas where skin tightening treatments have the most impact. NeckPerfect Complex is what I recommend between skin tightening sessions to maintain and extend results.

As a prescriber who offers thread lifts, radiofrequency and HIFU, I recommend NeckPerfect Complex to virtually every patient following neck and jawline treatments. Used consistently it meaningfully extends the visible results of those procedures between sessions.

Complete your neck and jawline routine

Apply NeckPerfect Complex morning and evening after your face routine, extending down the neck and décolleté. For additional firming from the face down, the Alastin Restorative Neck Complex, Revision Skincare Nectifirm ADVANCED and skinbetter science Techno Neck Perfecting Cream are the products I most consistently recommend alongside it for patients wanting a comprehensive neck protocol.

Frequently Asked Questions

Is it suitable if I am on GLP-1 medication?
Yes. Neck skin laxity is one of the earliest visible changes many GLP-1 patients notice. NeckPerfect Complex is one of the most targeted topical treatments for this specific area and is appropriate from the beginning of treatment rather than waiting for significant laxity to develop.

How does it compare to neck tightening procedures?
Radiofrequency, HIFU and thread lifts produce faster and more dramatic results for significant neck laxity. As a prescriber who offers these treatments, I find NeckPerfect Complex most valuable as a maintenance product between sessions rather than an alternative to procedures for significant laxity. For early-stage changes, it can delay the need for procedures meaningfully with consistent use.

Is it safe during pregnancy?
Yes. It is noted as safe for use during pregnancy, breastfeeding and for cancer patients in remission.

Is iS Clinical cruelty-free?
Yes. iS Clinical does not test on animals.

Is it vegan?
iS Clinical formulates without animal-derived ingredients in the majority of its products.

How to Use

Apply a small amount to clean skin morning and evening, smoothing evenly over the neck and décolleté using upward strokes. Extend application to the upper chest for best results.
