While those treatments are generally safe and minimally invasive, there are potential risks and complications to consider. Common side effects include temporary redness, swelling, bruising, and mild discomfort at the treatment sites, which typically resolve within a few days. In rare cases, complications such as infection, scarring, prolonged redness, uneven skin tone, or delayed healing may occur, particularly if proper aftercare is not followed. For treatments involving injections or microneedling, there is also a slight risk of irritation, scarring, or pigmentation changes in sensitive individuals.
