মুখের হাইপারপিগমেন্টেশন এবং রোদে পোড়া হওয়ার জন্য আমার কী এড়ানো উচিত?

It seems you are facing a heat rash which is a common condition. Your skin gets too hot due to the sun and it can make your skin red, itchy, and throbbing. After a time, you should avoid wearing clothes that are too tight. Make sure to wear cool, loose-fitting clothes. Moreover, always keep below clean and dry when there is a chance of heat rash. Calamine lotion can also be a good option to use to relieve the burning skin. Drinking enough water is important. 

I get why you're worrie­d about stopping Skinshine cream after 4 ye­ars. Being careful about side e­ffects makes sense­. When you quit, your skin might get red, itchy, or dry. That happe­ns because it got used to the­ cream. To avoid more problems, try using it le­ss over time. First, use it e­very other day. Then e­very two days. Keep doing that until you stop. Going slowly like­ this can let your skin adjust without too much trouble. Also, moisturize lots during this change­ to keep your skin healthy.

If you're dealing with oily skin, acne, pigmentation, or other skin issues, I recommend using "The Ordinary Niacinamide 10% + Zinc 1%" serum. This product helps reduce sebum production and acne occurrence. For moisturizing, try "Cetaphil Oil Control Moisturizer SPF 30" to keep your pores clear. You might also like "Neutrogena Oil-Free Acne Wash," which is gentle on skin affected by impurities. To protect your skin from sun damage, apply "CeraVe Ultra-Light Moisturizing Lotion SPF 30." These products can help give your skin a radiant appearance.

Your son might have a skin condition called hives. These are small, pinkish-red, itchy lumps that appear on the skin. Hives are generally caused by a person's allergic reaction to specific types of food, or drugs, or by bug bites. Give him an antihistamine that will alleviate the itchy skin and reduce the swelling. Moreover, you should search for the elements that cause the hives to not occur the rest of the time.
