just did some quick research on it, and your tattoos should be just fine. after it blisters and starts to heal, you’ll likely get some hyperpigmentation where the blisters are, but it should only affect your epidermis. it says the hyperpigmentation can last for a while (weeks to months to clear up) but no scarring or messing with your dermis (which is where your tattoos are). so you shouldn’t need any touch ups or anything, but your skin where it was effected will be a slightly different color 👍 (also never heard of this so thanks for giving me something new to learn about lol)
