What Causes Skin Laxity and Loss of Firmness?
Many people notice changes in their skin as they age. Skin may appear less firm, less lifted or more crepey than it once did.
These changes are often described as skin laxity.
While skin laxity is a natural part of ageing, there are several factors that can contribute to it. Understanding these factors can help you make informed decisions about your skin health.
What Is Skin Laxity?
Skin laxity refers to a loss of firmness and elasticity in the skin. Healthy skin contains important structural proteins such as collagen and elastin. These proteins help keep the skin firm, smooth and resilient.
Over time, collagen and elastin levels naturally decline. As this happens, the skin may begin to sag, loosen or appear less supported.
Common areas where skin laxity may occur include:
Jawline
Neck
Cheeks
Under-eye area
Décolletage
Arms and abdomen
Why Does Skin Lose Firmness?
Ageing and Collagen Decline
One of the most common causes of skin laxity is the natural ageing process.
Collagen production gradually decreases with age. Elastin fibres also become less effective over time. This can result in skin that appears thinner, looser and less firm.
Hormonal Changes
Hormonal fluctuations can affect skin quality at different stages of life. Many women notice changes during perimenopause and menopause. During this time, declining hormone levels may influence collagen production, hydration and skin elasticity. These changes can contribute to increased skin laxity and reduced skin firmness.
See our previous blog on how hormones can affect skin laxity here.
Weight Fluctuations
Significant weight loss or weight fluctuations can affect skin appearance. When body composition changes rapidly, the skin may not always adapt at the same pace.
Some people notice loose skin, changes in facial volume or reduced skin support following weight loss.
Sun Exposure
Long-term exposure to ultraviolet (UV) radiation can accelerate visible signs of skin ageing. UV exposure can contribute to collagen breakdown and reduce skin elasticity over time.
This process is often referred to as photoageing.
Daily sun protection remains one of the most important steps in supporting long-term skin health. Always wear SPF 50+ and reapply throughout the day. Some of our favourites include.

Lifestyle Factors
Several lifestyle factors may influence skin quality.
These can include:
Smoking
Poor sleep quality
Chronic stress
Inadequate nutrition
Dehydration
While these factors affect everyone differently, they may contribute to changes in skin appearance over time.
Can Skin Laxity Be Improved?
Skin ageing affects everyone differently. The most appropriate treatment approach depends on individual concerns, skin quality and overall health.
A personalised consultation can help identify the factors contributing to skin laxity and determine suitable management options.
At LUUM Aesthetics, treatment recommendations are tailored to the individual. Consideration is given to skin quality, lifestyle factors and personal goals.
For some patients, addressing internal factors such as hormonal changes, weight fluctuations or overall wellbeing may also form part of the conversation through LUUM Vitality consultations with Dr Sonia.
Understanding the Cause of Skin Laxity Is the First Step
Skin laxity is often influenced by multiple factors rather than a single cause. Ageing, hormonal changes, sun exposure, lifestyle factors and weight fluctuations can all play a role in how the skin looks and feels.
Understanding what may be contributing to these changes is an important first step towards creating a personalised plan that supports your skin health over time. Individual assessment is required. Treatment suitability varies between individuals.
