Sagging Skin: What Causes Loose Skin and How Can You Treat It?

Sagging skin is a common concern that affects people of all ages, particularly as we grow older or experience significant changes in body weight. It can appear in various areas of the body, such as the face, neck, arms or abdomen, and often leads to a loss of confidence or discomfort. But what exactly causes our skin to lose its firmness, and more importantly, can anything be done to prevent or reverse it?
In this blog, we will explore what sagging skin is, the most common causes behind it and the areas most likely to be affected. We will also share the most effective treatments available for sagging skin.
If you are considering clinical support, we will introduce how EF Medispa can help you safely and effectively treat sagging skin.
What is sagging skin?
Sagging skin refers to loose, drooping skin that lacks firmness and elasticity. It commonly occurs as a natural part of the ageing process or after significant weight loss.
This condition occurs when the skin’s collagen and elastin, which provide structure and support, gradually break down. As a result, the skin loses its ability to bounce back into place, leading to a sagging appearance.
Sagging skin can happen anywhere on the body, but is most common on the:
- Face
- Neck
- Arms
- Abdomen
- Inner thighs

Common causes of loose skin
Loose or sagging skin can develop for a variety of reasons, often due to changes in the skin’s structure and support over time. Some of the most common causes include:
- Ageing: As we age, the body naturally produces less collagen and elastic. These are two key proteins that keep the skin firm and elastic. This decline leads to thinner, looser skin.
- Weight loss: Significant or rapid weight loss, naturally or from treatments like Mounjaro, can leave excess skin behind, especially if the skin has been stretched for a long period and has lost its ability to contract.
- Pregnancy: During pregnancy, the skin stretches to accommodate a growing baby. After childbirth, the skin may not fully return to its original tightness.
- Sun exposure: Prolonged or unprotected exposure to UV rays breaks down collagen and elastic fibres in the skin. This accelerates the loss of firmness and elasticity.
- Genetics: Some people are genetically predisposed to developing loose skin. Especially as they age or experience weight fluctuations.
- Lifestyle factors: Poor nutrition, smoking, dehydration and lack of exercise can all contribute to the weakening of skin structure over time.
How to prevent saggy skin
While some factors like ageing and genetics are unavoidable, there are several effective ways to prevent or minimise sagging skin:
- Maintain a healthy weight: Aim for gradual weight loss instead of rapid drops to give your skin more time to adjust and tighten naturally.
- Stay hydrated: Drinking plenty of water keeps your skin hydrated, improving its elasticity and overall health.
- Eat a balanced diet: Focus on a healthy diet with nutrient-rich foods high in vitamins, A, C, E and protein, which support collagen production and skin repair.
- Protect your skin from the sun: Use sunscreen daily and avoid excessive sun exposure to prevent UV damage that breaks down collagen and elastic.
- Exercise regularly: Strength training and resistance exercises help build muscle mass, which can fill out loose skin and improve skin tone.
- Avoid smoking: Smoking reduces blood flow and damages collagen and elastic, accelerating ageing and sagging skin.
- Use skincare products with collagen boosting ingredients: Topical treatments containing retinoids, peptides or antioxidants can support skin firmness and repair.
