Avoid sunlight after Microdermabrasion and don’t go outside without applying a broad-spectrum sunscreen that has an SPF of 30 and protects your skin from both UVA and UVB. Skin gets mild red after the treatment and facing it to the sunburn can cause sunburn. It’s recommended to prevent sun exposure for at least 7 days and keep the skin covered with a big hat or a scarf. Sun exposure is harmful to even healthy skin, so you should be cautious even after the recovery time.
