Summer brings sunshine, vacations, and more time outdoors, but it can also bring skin challenges such as heat rash, sunburn, and stubborn hyperpigmentation. Hot, humid weather can trigger breakouts, irritation, and uneven skin tone. Here is how to keep your skin clear, calm, and glowing all season long.

Common Summer Skin Concerns and How to Manage Them

Heat Rash

Heat rash develops when sweat becomes trapped under the skin. It often appears as red, itchy bumps, especially where skin rubs together.

  • Stay cool: Wear breathable, loose-fitting clothing and avoid prolonged heat exposure.
  • Keep skin dry: Use a lightweight, talc-free powder to absorb excess moisture.
  • Soothe irritation: Apply aloe vera or hydrocortisone cream to calm redness and itching. If symptoms persist, our office can evaluate you and discuss prescription-strength treatment options.

Sunburn

Even when you use sunscreen, extended ultraviolet exposure can cause a painful burn.

  • Prevent exposure: Wear sun-protective clothing and stay out of direct sunlight during peak hours, generally from 10 a.m. to 4 p.m.
  • Act quickly: Take cool showers and apply a fragrance-free moisturizer to hydrate and soothe the skin.
  • Hydrate: Drink plenty of water and avoid further sun exposure until the skin heals.
  • Help prevent peeling: Apply moisturizer frequently while your skin recovers.

Hyperpigmentation and Dark Spots

Sun exposure can stimulate melanin production, leading to dark spots and uneven skin tone.

  • Wear sunscreen daily: A broad-spectrum SPF 40 or higher sunscreen helps prevent additional discoloration.
  • Consider professional treatment: Our ABMD Brightening Cream was specially formulated by Dr. Bajoghli and has been prescribed safely by our office for more than a decade. We also offer chemical peels, Pico laser treatments, Q-switched Nd:YAG laser treatments, and prescription therapies for stubborn pigmentation.

Oily and Acne-Prone Skin

Heat and humidity can increase oil production, clog pores, and contribute to breakouts.

  • Choose lightweight skincare: Replace heavy creams with oil-free, gel-based moisturizers.
  • Use a gentle cleanser: Wash your face twice daily with a mild, non-stripping cleanser to remove sweat and oil buildup.
  • Do not overdo it: Harsh scrubs and over-washing can irritate the skin and trigger additional oil production.

Chlorine and Saltwater Irritation

Pool chemicals and ocean water can dry the skin and cause sensitivity.

  • Rinse promptly: After swimming, rinse with fresh water to remove chlorine or salt.
  • Restore moisture: Apply a hydrating moisturizer or hyaluronic acid serum to replenish lost hydration.

When to Seek Professional Help

If a summer skin concern persists or worsens, professional care may help. A dermatologist can create a personalized skincare plan that may include customized peels, prescription products, or laser therapy.

Schedule Your Skin Check

Summer skincare is not only about appearance; it is an important part of keeping your skin healthy. Request an appointment to address a concern, refresh your routine, and protect your skin all season long.
