Is cortisone cream good for a burn after laser hair removal?

I would really encourage you to speak with your laser technician and their supervising physician. They will want to be aware of any issues you are having.  That is not typical for laser hair reduction.  Yes, you can use hydrocortisone if you have some inflammation.  Stay skintastic. 

Topical cortisone is a good treatment for any mild superficial burning after Laser Hair Removal but you may also want to add a topical antibiotic cream such as Bactroban if there are any concerns with secondary infection. In any case, you should immediately report any potential issues or side effects to your treating physician. Best.

Yes, cortisone cream is good because it will help prevent scarring and pigmentation problems. If infected, other creams are needed such as silvadene and bactroban. I like Biafine if the skin is not infected. Burns are rare with this procedure and are operator error almost always.
