Please recommend a good mask pack to use after laser treatment.

I had laser treatment to remove flat warts and moles.

I thought I took good care of it after that, but then I saw it pop up again in an area that looked like a flat wart.

I wonder if it will relapse even if I manage it with moisturizing cream and such.

If there is a mask pack you recommend for preventing recurrence, please let me know. Thank you^^
