Saunas are popular for relaxation and wellness, and some claim they make skin look younger. The short answer: a small study found people who used saunas regularly had a more stable skin barrier and better skin hydration than non-users, but there's no good evidence that saunas reduce wrinkles. Heat can also worsen rosacea and melasma. Treat the sauna as an occasional comfort, not an anti-aging treatment.

## What the research shows

In a controlled study of healthy volunteers aged 20 to 49, people with regular sauna exposure showed a more stable epidermal barrier, higher stratum corneum hydration, and faster recovery of water loss and skin pH after sauna, plus lower forehead sebum ([Kowatzki et al., *Dermatology*, 2008](https://pubmed.ncbi.nlm.nih.gov/18525205/)). The study was small and compared habits rather than randomizing people.

## Traditional vs infrared saunas

| | Traditional sauna | Infrared sauna |
|---|---|---|
| Heat source | Heated air and stones | Infrared lamps heat the body directly |
| Typical temperature | Hotter air | Lower air temperature |
| Skin evidence | Small barrier study | Little direct evidence for skin aging |

Infrared radiation is part of the "exposome," the environmental factors linked to skin aging, alongside sun radiation, pollution and tobacco smoke ([Krutmann et al., *J Dermatol Sci*, 2017](https://pubmed.ncbi.nlm.nih.gov/27720464/)). That's a reason not to assume more heat or infrared exposure is better for skin.

## Possible downsides

- **Rosacea flares:** heat is a common trigger.
- **Melasma:** heat may worsen pigmentation.
- **Dehydration and dryness:** long sessions can dry skin.
- **Health risks:** people with heart conditions, low blood pressure, or who are pregnant should ask a doctor first; avoid alcohol before or during sauna.

## Safe sauna habits for skin

1. Keep sessions moderate and stop if you feel unwell.
2. Drink water.
3. Remove makeup first.
4. Rinse and apply moisturizer afterward ([AAD: dry skin tips](https://www.aad.org/public/everyday-care/skin-care-basics/dry/dermatologists-tips-relieve-dry-skin)).
5. Avoid saunas right after laser, peels or microneedling until your provider approves.

## What actually slows skin aging

Daily sunscreen ([Hughes et al., *Ann Intern Med*, 2013](https://pubmed.ncbi.nlm.nih.gov/23732711/)) and a retinoid ([Weiss et al., *JAMA*, 1988](https://pubmed.ncbi.nlm.nih.gov/3336176/)) have far stronger evidence than sauna use.

## Red light vs infrared sauna

Red and near-infrared LED devices are different from infrared saunas; they deliver specific wavelengths without heating the body. Evidence for LED is still developing.

## Frequently asked questions

**Does sauna detox skin?** Sweating isn't a meaningful detox pathway; your liver and kidneys do that.

**Does sauna help acne?** Evidence is limited; sweat left on skin can irritate, so rinse afterward.

**Is infrared sauna safe for skin?** Usually for healthy people in moderation, but it isn't proven to reverse aging.

**How often is OK?** Many people use saunas a few times a week; check with your doctor if you have health conditions.
