Right after treatment, the area will likely be red and might feel like a mild sunburn for a few hours to a couple days. Some people experience slight swelling, especially in sensitive areas. The key things for aftercare are keeping the area clean and moisturized, avoiding hot showers or baths for 24-48 hours, and staying away from tight clothing that might irritate. No picking at the skin, even if it feels a bit rough or you notice hair 'shedding' in the following weeks - that's actually a good sign that the treatment worked. Gentle exfoliation after about a week can help with the shedding process.
