I had microneedling at plastic surgeon who did my subcision (her assistant did the microneedling). On 2nd treatment, I bled a lot. Now I have a red spot on my cheek that won't fade. It's 4mm at its widest. No bump or hardness underneath, and nothing about it has changed in 40 days. Looks like acne hyperpigmentation (I had a lot of hyperpigmentation after 2nd treatment, but most has been fading except for this spot). Been using 2% hydroquinone and it's done nothing.
