Toasted skin syndrome is a rash that develops in a fishnet-like pattern from direct, chronic, low-level exposure to heat sources such as laptops, electric blankets, heating pads, and heated car seats. The heat dilates superficial blood vessels under the skin, causing the rash.

People can take several measures to protect against winter dry skin, such as using an indoor humidifier, washing carefully, following a moisturizing routine, and covering exposed skin when outdoors.

A 2025 Finnish study found that rosacea often goes undiagnosed in people ages 70 or older. Researchers say this might be due to busy physicians with limited awareness of rosacea or patients’ own embarrassment or unwillingness to seek treatment.

Itchiness of the breasts or nipples isn’t common, but can signal conditions both harmless and serious. Minor reasons for itchiness across the bra area include eczema, psoriasis, exposure to soaps or detergents, trapped moisture, and pregnancy and breastfeeding. More serious causes include infections, breast surgery, radiation treatment, and certain rare forms of breast cancer. Any skin changes on the breast that don’t improve over weeks should be evaluated by a doctor.

Shingles occurs when the dormant chickenpox virus reactivates, causing tingling, burning, and a painful, blistering rash. Shingles can affect anyone who has had chickenpox, with higher risk after age 50 and in people with weakened immunity. Diagnosis and treatment within three days of the rash appearing can shorten the illness and reduce severity. Most people recover completely from shingles, but there may be complications, such as post-herpetic neuralgia, which is pain that can be severe and long-lasting. Vaccination is the best way to prevent shingles and its complications.

Red light therapy involves using devices that emit red or near-infrared light aimed at the skin. It is believed to reduce inflammation and boost production of collagen. Research suggests it can improve an array of skin problems, including fine lines, dark spots, redness, slow-healing wounds, scars, and acne. Unlike ultraviolet light, red light therapy isn’t associated with greater risks for skin cancer. Scientists are still determining the optimal doses of red light therapy for various skin conditions.

Toenail fungus, ingrown toenails, and brittle or cracked fingernails are common nail problems that affect older adults. They can make hands and feet unsightly and sometimes even painful. Treating these problems and preventing them from returning often takes a trial-and-error approach, diligence, and patience. Strategies include a combination of home remedies, over-the-counter medication, and good hygiene and grooming habits.

With age, people develop brown spots, wrinkles, and sagging skin. Women are more likely than men to invest money and time to look younger. Sun protection and a variety of skin care products can help, including those containing alpha-hydroxy acids, retinols, vitamin C, and hyaluronic acid. Minimally invasive cosmetic procedures can also ease signs of aging. These include injections of botulinum toxin (Botox) or hyaluronic acid, laser treatments, and chemical peels. Skin care and treatments should be customized to each person.

Spray-on sunscreens can be as effective as lotion-based sunscreens for protecting skin from harmful ultraviolet light. People using sunscreen sprays should make sure skin appears wet and shiny where they’ve sprayed and rub the product in before it dries.
