After treatment, keep the area clean and moisturized with gentle, fragrance-free products. Avoid hot water, intense exercise, and swimming for at least 24-48 hours. Don't apply makeup, perfumes, or irritating products on treated skin. Wear loose clothing to avoid friction on the area. Sunscreen is absolutely essential – use it every single day even if it's cloudy. Some people find that cooling gels or moisturizers specifically designed for post-treatment care help with any discomfort or redness.
