Summer heat, humidity, sweat, swimming and air conditioning can all affect the skin. A useful routine does not need harsh scrubs, essential oils or untested kitchen remedies. Consistent sun protection and gentle products are safer foundations.

Protect skin from ultraviolet radiation

The American Academy of Dermatology recommends a broad-spectrum, water-resistant sunscreen with SPF 30 or higher. For more context, read why wearing sunblock is important. Apply it to exposed skin before going outdoors and reapply according to the label, particularly after swimming or heavy sweating.

Sunscreen works best alongside shade, protective clothing, a wide-brimmed hat and UV-protective sunglasses. No sunscreen blocks all ultraviolet radiation.

Cleanse without stripping the skin

After heavy sweating or swimming, rinse the skin and use a mild cleanser where needed. Scrubbing aggressively can worsen irritation. Pat sweat away with a clean towel instead of repeatedly rubbing the face.

Choose products for your skin

A fragrance-free moisturizer can help when sun, pool water or air conditioning leaves skin dry. People prone to acne can look for products labelled non-comedogenic or oil-free. See also our guide to gentle acne and skin care. Sensitive skin may tolerate fragrance-free mineral sunscreens containing zinc oxide or titanium dioxide more comfortably.

Avoid irritating home treatments

Lemon or other citrus juice on skin can react with sunlight and cause a painful blistering rash or pigmentation. Essential oils and fragrances can trigger irritation or allergic contact dermatitis. Undiluted mixtures, abrasive powders and claims that food masks remove acne or dark spots should not replace appropriate skin care.

When to see a dermatologist

Persistent acne, changing dark patches, an unexplained rash, blistering sunburn or a changing mole deserves professional assessment. Treatment depends on the diagnosis and skin type; a routine that helps one person may irritate another.
