Beyond the Face: Why décolletage Rejuvenation Is the Next Big Trend in Regenerative Aesthetics

Looking Younger Is No Longer Just About the Face

As facial rejuvenation becomes more common, patients are paying greater attention to the neck, chest, and hands—areas that often reveal age first.

Among them, the décolletage is particularly vulnerable to sun exposure, collagen loss, and skin laxity. Rather than seeking more volume, today's patients want healthier, firmer skin with natural-looking results.

This shift has made hyperdiluted CaHA one of the fastest-growing regenerative treatments for chest rejuvenation.

Why Hyperdiluted CaHA?

Unlike traditional fillers that primarily restore volume, hyperdiluted CaHA works as a collagen biostimulator, encouraging the skin to regenerate from within.

Benefits

• Stimulates collagen and elastin production
• Improves skin firmness and elasticity
• Softens horizontal chest lines
• Enhances overall skin quality
• Delivers gradual, natural-looking results

Clinical Application

Hyperdiluted CaHA is applied to the décolletage—the upper chest between the lower neck and the breasts, rather than the breast tissue itself.

Treatment Overview

Dilution: 1:2

Injection Plane: Subcutaneous layer

Technique: A 22–23G blunt cannula is commonly used with a fan-shaped technique for even distribution. Prominent wrinkles may be treated using retrograde linear threading with a cannula or a slightly bent 27G needle for greater precision.

Recommended Volume: 2–3 syringes per side (1 mL each), adjusted according to individual skin condition.

Patient Comfort: Topical anesthesia or lidocaine-assisted dilution may be used to reduce discomfort during treatment.

Treatment protocols should always be determined by qualified healthcare professionals based on clinical judgment and local regulations.
