Not recommended at all this offers is a scam. They offer you a free consultation, then they change it where you have to pay but only tell you once it's too late. I was concerned about stretch marks and they kept trying to sell me their products for something else. Something I didn't even ask about but was told I should care for. Terrible service! It's all about the money. Find somewhere else.
It appears that the cyst in the picture is still inflamed. For that I would recommend you see a dermatologist as you will benefit from topical and even short course of systemic antibiotics. If this is a recurrent problem, a regimen with retinoids and topical antibiotics to prevent recurrence and improve the current condition is important.
