Survey/marketing data from a beauty industry report. 気になる ('to be bothered by, be concerned about') is a key verb for expressing interest/anxiety about appearance or situations. 肌理 ('skin texture') is an uncommon kanji compound (the reading is 'kime' or 'hadari') — native speakers often write it in kana. 方 is the polite counter/noun for 'person' in formal contexts. ~を越える 'to exceed.'
