A painful pimple on the neck for a few days may occur due to a skin infection or blocked hair follicle. Keeping the area clean and avoiding squeezing or pressing the swelling may help prevent further irritation. Warm compresses may help reduce pain and support natural healing. Consult a doctor if the swelling increases or does not improve.

A single pus-filled pimple on the glans that bursts within a day is most commonly a minor local skin infection, such as folliculitis or irritation, and not necessarily a sexually transmitted disease (STD), especially if there was no recent unprotected sexual contact. Using someone else's undergarment can introduce bacteria or cause friction and may have contributed to the problem, so it is best avoided. Keep the area clean and dry, wash gently with mild soap and water, avoid squeezing or touching it, and wear loose, clean cotton underwear. Such lesions usually heal on their own in a few days. However, if you notice multiple sores, ulcers, persistent pain, discharge, fever, or if the lesion does not heal, consult a doctor to rule out STDs or other infections and get appropriate treatment.

Yes, Pernex AC 2.5% Gel contains Benzoyl peroxide, which can help treat acne (pimples) on the back by reducing bacteria and clearing pores. It may also slightly improve marks left after acne, but it is not specifically meant for hyperpigmentation (dark spots). Apply a thin layer once daily initially to avoid irritation, and use a moisturiser if dryness occurs. If pigmentation persists, you may need additional treatment as advised by a doctor.

Pernex AC 2.5% Gel can be used for pimples as it contains benzoyl peroxide, which helps reduce acne-causing bacteria, unclog pores, and decrease inflammation in acne lesions. It is usually applied once daily in a thin layer to the affected areas, as advised by a doctor. Improvement is gradual and may take a few weeks of regular use, depending on acne severity and skin sensitivity. Mild dryness, redness, or irritation can occur, especially in the initial days of treatment. If irritation is significant or there is no improvement, consult a dermatologist for proper evaluation and treatment.

A small hard lump on the forehead may occur due to a cyst, blocked gland, or a harmless fatty growth. If it is painless and not increasing in size, it is usually not a serious problem. Avoid pressing or touching the lump repeatedly. Consult a doctor if the lump increases in size, becomes painful, or shows any changes.

To treat acne and fade spots, wash your face twice daily, avoid picking pimples, and use a gentle oil-free moisturiser. A night cream with benzoyl peroxide helps clear acne, while niacinamide or vitamin C can lighten dark spots. If you have frequent breakouts or marks that do not fade, see a dermatologist.
