Yes. While the skin is vulnerable to ultraviolet radiation immediately after treatment, microneedling can be safer than many other harsher treatments. However, you'll likely need to make some adjustments to your summer routine, including staying out of the sun and heat. Here are some basic precautions you'll need to take if you have microneedling during the summer: Avoid sun exposure for a couple of weeks before and after treatment, Apply (and reapply!) sunscreen with an SPF of 30 or higher (after the first 24 hours), Wear sunglasses and wide-brimmed hats, Moisturize daily, Don't peel or pick at sensitive, healing skin, Avoid peak sunlight hours if possible (from noon to 4 p.m.), Don’t make a splash—stay out of the pool until your skin has healed completely.
