Cool water, gentle products, and a short shower are the keys to washing sunburnt skin without making the pain and damage worse. A sunburn is an inflammatory injury, and everything you do in the shower either calms that inflammation or amplifies it. Here’s how to get clean comfortably while giving your skin the best chance to heal.
Use Cool Water, Not Cold or Hot
Set your shower to cool or lukewarm. Cool water helps reduce the inflammation happening in and around the burn, which is why it feels immediately soothing. Hot water does the opposite: it dilates blood vessels, increases blood flow to already-inflamed skin, and intensifies pain and swelling. Even warm water that would feel normal on healthy skin can sting badly on a sunburn.
You don’t need to blast yourself with ice-cold water either. That can shock the skin and cause its own discomfort. Think cool tap water, the kind that feels refreshing but not jarring.
Keep It Short
Spending too long in the shower dries out your skin, even when the water is cool. Sunburnt skin has a compromised moisture barrier, meaning it loses water faster than healthy skin does. A quick rinse of five to ten minutes is enough to cool the burn, clean your body, and get out before you strip away more of the moisture your skin is trying to hold onto.
You can shower more than once a day if it brings relief. Cool showers or baths several times a day are a standard recommendation for managing sunburn discomfort. Just keep each session brief.
What to Use (and What to Skip)
Your sunburnt skin is raw and reactive, so this is not the time for your usual body scrub, exfoliating wash, or anything with fragrance. Use a gentle, fragrance-free cleanser and apply it lightly with your hands rather than a washcloth or loofah. Mechanical scrubbing on inflamed skin tears at the damaged outer layer and can worsen peeling later.
Specifically avoid products containing:
- Retinols, AHAs, or BHAs (common in acne washes and anti-aging cleansers), which increase skin sensitivity
- Alcohol-based products, which dry out already-dehydrated skin and can trap heat
- Harsh soaps or antibacterial washes, which further strip the skin’s protective barrier
If you want something soothing in the shower itself, colloidal oatmeal works well. It has direct anti-inflammatory and antioxidant properties that reduce scaling, roughness, and itch. You can find colloidal oatmeal bath products at most drugstores, or simply let an oatmeal-based wash sit on the skin briefly before rinsing. It won’t cure the burn, but it noticeably calms the itch and tightness.
How to Dry Off Without Making It Worse
When you step out, resist the urge to towel off the way you normally would. Rubbing a towel across sunburnt skin creates friction that irritates the burn and can pull off skin that’s beginning to peel. Instead, gently pat yourself dry with a soft towel. Leave your skin slightly damp, not dripping but not fully dry either. That residual moisture is going to help with the next step.
Moisturize While Your Skin Is Still Damp
This is the most important thing you do after the shower. While your skin is still damp, apply a thick, fragrance-free moisturizer. The dampness on your skin acts as a layer of hydration, and the moisturizer seals it in. Waiting until your skin is fully dry means you’ve already lost that window.
Moisturizers containing aloe vera are a popular choice and feel soothing for many people, but aloe isn’t strictly necessary. What matters more is using a thick emollient cream or ointment that locks in moisture. Sunburns dry your skin out significantly, and that dryness drives the tightness, itching, and flaking that follow.
There are a few things to avoid putting on your skin after a shower:
- Petroleum jelly, which can trap heat in the skin
- Products containing benzocaine or lidocaine, which are numbing agents that can cause allergic reactions on damaged skin
- Anything with alcohol, which dries and irritates
Stick with a simple, heavy moisturizer and reapply throughout the day as your skin absorbs it. If your skin is peeling, keep moisturizing through the peeling phase. Don’t pick at or pull loose skin.
When Showering Isn’t the Priority
Most sunburns are first-degree burns that are painful but manageable at home. If your sunburn has progressed beyond that, a shower routine is secondary to getting medical attention. Blisters indicate a second-degree burn, and large or widespread blistering can lead to dehydration, skin infection, and other complications.
Signs that your sunburn needs professional care include bright red or oozing skin, severe pain that isn’t responding to cool compresses, fever, chills, nausea, vomiting, or headache. These symptoms suggest sun poisoning, a more serious systemic reaction that goes beyond surface-level skin damage. If blisters are present alongside any of those symptoms, skip the home care routine and get evaluated.
