It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "The people of Paradise will be hairless, beardless, and with kohl-lined eyes; their clothes will not wear out, nor will their youth ever fade."

Brief Explanation
(Explanation of Ahadith 2859 to 2861)
«جُرْدٌ» refers to a person who does not have hair on his body, armpits, pubic area, etc., and «مُرْدٌ» is the plural of "amrad," and "amrad" refers to a person who has not grown a beard or mustache, is in the prime of youth, and the absence of hair in these places will be a cause of beauty and attractiveness in Paradise. And «كُحْلٌ» is the plural of "kaheeli," which means "akhal," that is, one whose eyelashes are long and the roots are black, as if kohl has been applied.
All these attributes are of the beauty and youth of the people of Paradise.
