7 natural ways to get rid of loose skin

Loose skin after weight loss or pregnancy is incredibly common, and while it can be frustrating, there are natural ways to improve skin elasticity without surgery. These seven evidence-based approaches can help tighten loose skin over time.

1. Build Muscle Through Strength Training

Filling out loose skin with lean muscle is the single most effective natural approach. When you lose a significant amount of weight, the space left behind can make skin appear saggy. Resistance training builds muscle mass that fills that space, creating a firmer, more toned appearance.

Focus on compound exercises that work large muscle groups: squats, deadlifts, bench press, rows and overhead press. Aim for three to four sessions per week, progressively increasing the weight over time. Results won’t appear overnight, but after three to six months of consistent training, the difference is usually visible.

2. Stay Properly Hydrated

Hydrated skin is more elastic and resilient. The NHS recommends six to eight glasses of water daily, but if you’re active or trying to improve skin quality, aiming for two litres is sensible. Dehydrated skin loses elasticity faster and appears more wrinkled and saggy.

Water isn’t the only factor – electrolytes matter too. Adding a pinch of sea salt to your water or eating potassium-rich foods like bananas and sweet potatoes helps your body retain fluid at a cellular level.

3. Eat Enough Protein and Collagen-Rich Foods

Collagen is the protein responsible for skin structure and elasticity. As we age, collagen production naturally decreases, but diet can help support it. Bone broth, chicken skin, fish with the skin on, egg whites and citrus fruits all support collagen production.

Protein intake matters more broadly too. Aim for at least 1.6g of protein per kilogram of body weight daily if you’re strength training. This supports both muscle building and skin repair. Good sources include chicken, fish, eggs, Greek yoghurt, lentils and tofu.

4. Use Retinol and Vitamin C Topically

Retinol (vitamin A) is one of the most researched ingredients for improving skin elasticity. It stimulates collagen production and increases cell turnover, gradually improving skin texture and firmness. Start with a low concentration (0.25-0.5%) and build up gradually to avoid irritation.

Vitamin C serum applied topically also supports collagen synthesis and protects against UV damage that breaks down existing collagen. Look for serums containing L-ascorbic acid at 10-20% concentration. Apply vitamin C in the morning and retinol at night for best results.

5. Don’t Lose Weight Too Quickly

Rapid weight loss gives skin less time to adapt to your changing body shape. Losing more than 1kg per week significantly increases the likelihood of loose skin compared to a gradual approach. If you’ve already lost weight quickly, the good news is that skin can continue to tighten for up to two years after weight loss stabilises.

If you’re still in the process of losing weight, aim for 0.5-1kg per week. This rate preserves more muscle mass and gives your skin the best chance of keeping up with the change.

6. Protect Your Skin From Sun Damage

UV radiation is the number one external cause of collagen breakdown and premature skin ageing. Wearing SPF 30 or higher daily – even on overcast days – helps preserve the collagen and elastin that keep skin firm. The British Association of Dermatologists recommends reapplying every two hours during prolonged sun exposure.

This applies to all skin tones. While darker skin has more natural UV protection, it’s still susceptible to collagen damage from sun exposure over time.

7. Consider Collagen Supplements

The evidence for collagen supplements has strengthened considerably in recent years. A 2023 meta-analysis published in the Journal of Cosmetic Dermatology found that hydrolysed collagen supplements taken for 90 days or more improved skin elasticity and hydration compared to placebo.

Look for hydrolysed collagen peptides (types I and III) at a dose of 5-10g daily. Marine collagen and bovine collagen are the most widely available. Take it consistently for at least three months before judging results. For more wellness advice, see our guide to healthy daily habits.

Frequently Asked Questions

Can loose skin tighten naturally after weight loss?

Yes, skin can continue to tighten for up to two years after weight loss stabilises. Factors like age, how much weight was lost, how quickly it was lost and genetics all affect how much natural tightening occurs.

What is the best exercise for tightening loose skin?

Strength training is the most effective exercise for loose skin because it builds muscle mass that fills out the space beneath the skin, creating a firmer appearance.

Do collagen supplements actually work for loose skin?

Recent research suggests hydrolysed collagen supplements can improve skin elasticity when taken consistently at 5-10g daily for at least 90 days. Results vary between individuals.
