Rosacea is a chronic, inflammatory disorder often confused with acne. “While there are multiple types, the two most common include redness of the cheeks (flushing) and an over-abundance of little visible vessels on the cheeks, as well as acne-like bumps generally more in the mid face,” says dermatologist Dr Dhaval G. Bhanusali. Unlike acne, rosacea is commonly triggered by histamine-related response and by spicy foods, caffeine and alcohol. Treatments usually combine dietary and lifestyle changes, prescription topicals, and switching to non-irritating skin-care formulas.
Folliculitis (a common summer skin problem) is an inflammation of the hair follicles, characterised by tiny, red pimples, which may be come filled with pus (resembling whiteheads). They can also be itchy or painful, or in more severe cases become crusty sores. They can appear anywhere on the body – particularly areas where friction is common, like the thighs, butt, neck and armpits. According to dermatologist Dr Francesca Fusco, folliculitis can be caused by bacteria and comes in several versions. Some examples include bacterial folliculitis, also known as barber’s itch because it tends to affect men’s beard area, and pseudomonas folliculitis, aka hot tub itch because the responsible bacteria is most commonly found in warm contaminated water. Mild cases of folliculitis can be treated with non-prescription benzoyl peroxide- and salicylic acid-based, wipes and creams. More severe cases may require oral antibiotics. For folliculitis that involves a yeast infection, there are anti-yeast cleansers; often a prescription-strength anti-fungal medication may be required.
Keratosis pilaris is a chronic skin condition, marked by rough (red, white, or skin coloured) bumps – usually on the upper arms and legs – that can feel like sandpaper. According to Dr Bhanusali, these tiny bumps are caused by an abnormal amount of keratin that blocks hair follicles. While the condition is harmless, it can cause itchiness and dryness – moisturisers can help ease these symptoms. Dermatologist Dr Debra Jaliman, recommends treating keratosis pilaris with topical retinoids and creams containing salicylic acid and lactic acid, which work to remove dead skin cells and prevent clogged follicles.
