Everything You Need to Know About Skin Laxity

Monique Radatti • January 14, 2026

Skin laxity, often described as sagging or loose skin, is one of the most common concerns we address at MUSE By Monique. It's a natural, inevitable part of the ageing process, but understanding what causes it and how it can be managed is key to maintaining a feeling of confidence in yourself and in your skin.


Here is a breakdown of everything you need to know about skin laxity.

Simply put, skin laxity refers to the loss of elasticity and firmness in the skin, resulting in a loose or drooping appearance. It happens across the body, but is most noticeable on the face, neck, and jawline.


The three main culprits behind skin laxity are:



  • Loss of Essential Proteins: The dermal layer of your skin is supported by a network of collagen and elastin fibres. Collagen provides structure and firmness, while elastin allows the skin to stretch and snap back into place. As we age, the production of these proteins slows dramatically, and existing fibres break down.
  • Structural Volume Loss: Below the skin, the underlying bone and fat pads that support your facial structure begin to shrink and migrate. This loss of deep volume removes the foundational support, causing the overlying skin to appear loose and saggy (as seen in the deepening of the NLF and the development of jowls in the 40s and 50s).
  • Environmental Factors: Unprotected exposure to the sun's UV rays is the number one accelerator of skin laxity. UV radiation damages collagen and elastin fibres at a faster rate, leading to premature sagging and a loss of skin elasticity.

While treatments offer excellent support, consistent daily prevention is crucial for minimising damage and maintaining long-term skin health. Sunscreen is a non-negotiable for maintaining skin health and preventing premature ageing.



  • Prioritise SPF: Wearing a broad-spectrum SPF every day helps protect against harmful UV rays, which are the biggest accelerator of collagen and elastin breakdown. This significantly reduces the long-term appearance of lines and loss of elasticity.


Antioxidant Support: Incorporating skincare products rich in antioxidants (like Vitamin C and E) helps fight the free radical damage caused by environmental factors and further protects your skin's collagen.

If laxity has already occurred, we have treatments specifically designed to address it by stimulating your skin's natural repair process and restoring underlying support. Our goal is always to provide subtle, refined support tailored to you.


Through a thorough consultation and detailed facial assessment, we evaluate the specific severity of your skin laxity in key zones, including the lower third (jawline definition and skin laxity).


Your personalised plan may involve:



  • Collagen Stimulation: Treatments focused on boosting your skin's ability to produce new collagen and elastin, which helps to tighten and firm the skin over time.
  • Volume Support: Using volume improving treatments to restore the lost structural support beneath the skin.

Skin laxity is manageable, and a personalised plan focusing on both prevention and renewal is the key to maintaining your skin’s firmness. Reach out or book a private consultation with Nurse Monique to discuss your options.
