Red, burning skin is often a sign of mild irritation, contact dermatitis, or a sunburn. To soothe the area, apply a cool, damp compress followed by pure aloe vera gel or a plain moisturiser like petroleum jelly. For mild inflammation, you can apply an over-the-counter hydrocortisone cream (0.5% to 1%) twice daily. If you suspect an allergic reaction, an oral antihistamine like cetirizine or loratadine can help. Avoid harsh soaps, hot water, and scented products while your skin heals. If the redness spreads rapidly, blisters, or does not improve within a few days, please consult a healthcare professional.
