Hi. Greetings. Fractional laser treatment cost can vary depending on number of scars, the city and centre where you take treatment and the the type of laser used. Cost may vary from three to eight thousand usually. Creams alone will be of no help. For chicken pox scars, you'll need scar punch excision or TCA treatment or laser treatment. Discuss with you dermatologist or send pics on follow up chat. Hope this helps.
