Welcome to the forum, and thank you for posting. I’m sorry that your treatment has left you concerned.
That does look like overtreatment. The most important thing to do right now is to keep the area clean and do not pop any blisters or pick any scabs. Continue to use a mild cleanser and 100% aloe vera gel with no menthol. Avoid sunlight in that area and consider using a triple antibiotic ointment to keep the skin as bacteria-free as possible.

After the inflammation has gone down, I recommend getting some silicone sheeting to help mitigate long-term effects.
Out of curiosity, were you using a topical anesthetic during treatment? Sometimes those anesthetics can reduce pain to the point that it’s hard to feel if you’re getting overtreated.
