Red, itchy pimples in the pubic area that sometimes turn dark and slowly spread can happen due to a few different reasons, like fungal infection, bacterial folliculitis (infection of hair roots), irritation from shaving or sweating, or sometimes skin conditions like dermatitis. Because this area is warm and moist, infections can spread more easily, especially if there is friction, tight clothing, or excessive sweating. The fact that it is spreading suggests it should not be ignored or treated only with random products. Ketostar soap may help a bit if there is fungal involvement, but it is not enough if there is mixed infection or follicle inflammation, and in some cases, it may not be the right choice at all. Avoid scratching or squeezing the bumps because that can worsen the spread and dark marks. Keep the area clean and dry, wear loose cotton clothing, and avoid shaving until it improves. Since it is spreading to the legs and body and changing colour, it is important to get a proper skin examination. A dermatologist can check whether it is fungal, bacterial, or inflammatory and give targeted treatment so it clears properly instead of recurring.

Long-standing irritation in both legs with darkening of skin for years often happens when the skin keeps going through a cycle of inflammation, scratching, and healing, which leads to thickened and darker skin over time. This is commonly seen in conditions like chronic eczema, contact dermatitis, fungal overlap, or even lichen simplex, where repeated itching itself keeps the problem active even if basic blood tests are normal. In some cases, strong steroid creams used for long periods can also thin and irritate the skin or temporarily mask infection, making the problem harder to fully settle. When this becomes long-term, the focus shifts from only treating infection to breaking the itch?scratch cycle and repairing the skin barrier. Gentle cleansing, regular moisturising, avoiding harsh soaps, and preventing friction from tight clothing can help slowly calm the skin. Long-term use of combination creams with steroids and antibiotics is usually not ideal without review because it may worsen resistance or skin damage. Since you are not improving despite treatment, a proper dermatology reassessment is important to confirm the exact cause and adjust therapy, as chronic skin conditions often need a different long-term maintenance plan rather than repeated short treatments.
