After microneedling treatment, it is important to keep the skin moisturized and protected from sun exposure. You should use a gentle, fragrance-free moisturizer and avoid using exfoliating products for at least 24 hours. Sunscreen with at least SPF 30 should be applied daily to protect the skin from UV damage. It is also important to avoid sweating and hot showers for the first 24 hours after treatment. If you experience redness or irritation, you can use a cold compress to reduce inflammation. Avoid using makeup or other cosmetics on the treated area for at least 24 hours. It is also recommended to avoid any excercise or physical activities that may cause excessive sweating for the first 24 hours.
