The Impact of Exercise on Skin Health

Last updated: 5 August 2026

The relationship between exercise and skin health is more complex and fascinating than most people realise. Whilst the immediate post-workout flush might suggest that exercise is purely beneficial for the skin, the reality involves a nuanced relationship of positive and potentially negative effects. Practitioners take an overall view of skin health that encompasses lifestyle factors, including physical activity, as part of every treatment plan.

The positive effects of exercise on skin

Enhanced blood flow and nutrient delivery

During exercise, cardiac output increases by up to fivefold, dramatically boosting blood flow to the skin. Research published in the Journal of Investigative Dermatology has demonstrated that this increased perfusion delivers more oxygen, nutrients, and growth factors to the dermis, supporting fibroblast function and collagen production.

A landmark 2014 study at McMaster University, published in Cell Metabolism, found that regular exercise in adults over 65 produced measurably thicker dermis and more compact stratum corneum, essentially reversing microscopic hallmarks of skin ageing. The researchers attributed this to myokines, signalling molecules released by contracting muscles that have systemic anti-ageing effects.

Stress reduction and cortisol management

Regular moderate exercise is one of the most effective natural cortisol regulators. Since chronic elevated cortisol degrades collagen, increases sebum production, and impairs barrier function, the stress-reducing effects of exercise translate directly into skin health benefits. A 2021 study in Psychoneuroendocrinology confirmed that consistent exercise reduced both baseline and stress-induced cortisol levels by 15-25%.

Improved lymphatic drainage

Unlike the cardiovascular system, the lymphatic system has no central pump and relies on muscle contraction to move lymph fluid. Exercise, particularly activities involving rhythmic movement, enhances lymphatic drainage, reducing facial puffiness, supporting immune surveillance, and helping clear cellular waste products from the skin.

Better sleep quality

Regular exercise improves both sleep duration and quality, as documented in a meta-analysis published in Sleep Medicine Reviews. Since the skin’s most intensive repair processes occur during deep sleep, improved sleep indirectly benefits skin regeneration and healing.

Anti-inflammatory effects

Regular moderate exercise produces systemic anti-inflammatory effects through the release of anti-inflammatory myokines (particularly IL-6 and IL-10). Research in Nature Reviews Immunology has shown that this exercise-induced anti-inflammatory state can benefit inflammatory skin conditions including acne, rosacea, and eczema.

Potential negative effects

UV exposure from outdoor exercise

Outdoor exercise significantly increases UV exposure. A study in the British Journal of Sports Medicine found that outdoor athletes had measurably higher levels of photoageing and skin cancer risk compared to indoor exercisers. This risk is easily mitigated with consistent SPF 30+ application, UV-protective clothing, and timing exercise to avoid peak UV hours (10am-4pm).

Sweat-related irritation

Whilst sweat itself is not harmful, prolonged contact with sweat can disrupt the skin’s pH balance, irritate sensitive skin, and, if combined with friction, contribute to conditions such as miliaria (heat rash) and folliculitis. The salt content of sweat can also dehydrate the skin surface if left to evaporate without rinsing.

Free radical generation

Intense exercise increases oxygen consumption by up to twentyfold, which generates free radicals as a metabolic by-product. Research in Free Radical Biology and Medicine has shown that whilst moderate exercise upregulates the body’s antioxidant defences, extremely intense or prolonged exercise can temporarily overwhelm these defences, creating oxidative stress that may affect the skin.

Mechanical Stress

High-impact activities create repetitive mechanical forces on facial tissue. Running, for example, subjects the face to gravitational forces that may contribute to skin laxity over time, though the evidence for this is primarily observational and must be weighed against the numerous benefits of cardiovascular exercise.

Exercise and specific skin conditions

• Acneexercise can improve acne through stress and inflammation reduction, but sweat and friction can trigger breakouts if not managed with proper cleansing
• Rosaceaexercise-induced flushing can trigger flares; opt for cooler environments, lower intensity, and cold water misting
• Eczemasweat can irritate eczema; shower promptly after exercise and apply moisturiser
• Psoriasismoderate exercise has been associated with reduced flare frequency in several studies

Optimising exercise for skin health

Our evidence-based recommendations:

1. Cleanse before exerciseremove makeup and excess oil to prevent pore congestion during sweating
2. Apply SPF for outdoor exercisewater-resistant SPF 30+ minimum, reapplied every two hours
3. Cleanse promptly after exerciseremove sweat, bacteria, and debris with a gentle cleanser
4. Moisturise post-showerreplenish hydration depleted by showering and sweat evaporation
5. Stay hydratedinternal hydration supports skin hydration and post-exercise recovery
6. Choose appropriate intensitymoderate, consistent exercise produces the best skin benefits
7. Consider antioxidant supplementationfor very active individuals, additional vitamin C and E may help manage exercise-induced oxidative stress

Frequently asked questions

Does exercise really make you look younger?
Yes, the evidence is compelling. The McMaster University study demonstrated that regular exercisers over 65 had skin structure comparable to 20-30-year-olds. The combination of improved circulation, reduced cortisol, enhanced collagen production, and better sleep creates genuinely measurable anti-ageing effects.

Should I wear makeup when exercising?
We strongly recommend exercising with a clean face. Foundation, concealer, and other occlusive products can trap sweat and bacteria in the pores, increasing the risk of breakouts and irritation. If you prefer not to exercise bare-faced, use a lightweight, non-comedogenic mineral SPF as an alternative.

Is yoga or weight training better for skin?
Both offer skin benefits through different mechanisms. Yoga reduces cortisol and improves circulation through inversions. Weight training stimulates growth hormone release and promotes collagen production through mechanical loading. A combination of cardiovascular, resistance, and flexibility training produces the most comprehensive health and skin benefits.

Can I exercise after aesthetic treatments?
We generally recommend avoiding strenuous exercise for 24-48 hours after injectable treatments and 48-72 hours after skin resurfacing procedures. Your practitioner will provide specific guidance based on your treatment. When you resume exercise, start gently and monitor your skin’s response.
