What happens to excess skin when you lose weight?

Professor Ash Mosahebi

When you lose weight, your skin may not shrink back immediately, especially if the weight loss is significant. For small to moderate weight loss, skin often retracts naturally over time due to its natural elasticity.

However, with large weight loss (like after bariatric surgery), the skin can remain loose because it has been stretched for too long, causing a loss of elasticity. In some cases, lifestyle changes and non-surgical treatments can improve the appearance of loose skin, but excess skin removal surgery is often the most effective solution for large amounts of loose skin.

What causes loose skin?

Loose skin after weight loss occurs because the skin's collagen and elastin fibres — which give the skin its stretch and firmness — may not fully recover. Here’s a closer look at what causes it:

  1. Loss of skin elasticity: Over time, the skin's collagen and elastin production naturally decreases. When skin is stretched for extended periods (like during weight gain), it loses its ability to snap back, especially in older adults.
  1. Amount of weight lost: The more weight you lose, the harder it is for the skin to retract. People who lose a small amount (10-20 pounds) are more likely to see their skin adjust naturally. However, for those who lose 50+ pounds, the skin may not shrink back on its own.
  1. Speed of weight loss: Rapid weight loss, like that seen with crash diets or bariatric surgery, doesn't give the skin enough time to adjust, increasing the risk of loose skin. Gradual weight loss is better for maintaining skin elasticity.
  1. Age: As you age, your skin produces less collagen and elastin, making it more difficult for the skin to bounce back after weight loss.
  1. Genetics and skin quality: Everyone’s skin responds differently to weight loss. Some people naturally have better skin elasticity due to their genetics or skin care habits.

Excess skin causing problems

Excess skin isn't just a cosmetic concern — it can also lead to physical discomfort and hygiene issues. When large amounts of loose skin fold over itself, it can trap moisture and cause skin irritation, rashes, or infections. For some people, the weight of excess skin also makes it difficult to move or exercise comfortably.

When can excess skin become a problem?

  • Skin irritation or rashes: Moisture and sweat can get trapped in skin folds, leading to rashes, chafing, or fungal infections.
  • Physical discomfort: Heavy, sagging skin can make certain movements uncomfortable, especially around the stomach, thighs, or arms.
  • Reduced mobility: Loose skin around the thighs, arms, or abdomen can restrict movement and make exercise feel awkward or painful.
  • Hygiene challenges: Cleaning underneath skin folds can be difficult, leading to hygiene issues or bad odours.
  • Aesthetic concerns: For many people, loose skin affects confidence and body image, especially when it’s visible in clothing or swimwear.

How to get rid of excess skin

If loose skin is causing discomfort or self-esteem issues, there are several options to address it.

  1. Lifestyle changes: Building muscle through resistance training, eating a balanced diet, and staying hydrated can improve skin elasticity. However, lifestyle changes are most effective for mild to moderate cases of loose skin.
  1. Non-surgical treatments: Treatments like IPL, ultrasound skin tightening, and chemical peels can stimulate collagen production, firming up mild to moderate loose skin.
  1. Surgical option – Excess skin removal: For large amounts of loose skin, surgical removal is often the most effective solution. Procedures like tummy tucks, arm lifts, and thigh lifts physically remove the excess skin, providing a firmer, smoother appearance. While this method requires downtime for recovery, it offers lasting results.

If you’re unsure which option is best for you, it may be helpful to schedule a consultation to discuss the level of excess skin and possible treatment options.
