Use of facial cosmetics and their effects on skin among female students of Bayero University Kano, Nigeria

Abstract

Cosmetics are used for cleansing, beautifying, enhancing attractiveness, or altering appearance and commonly applied by young women. This study examined the use and effects of cosmetics on the skin of female students at Bayero University Kano, Nigeria. A sample of 360 students from five faculties were randomly selected. Data on age, purpose, type, frequency of use, and effects of cosmetic products were collected. The age groups were divided into younger (18-25 years) and older (25+ years). Pearson’s Chi-square test assessed associations between age, ethnicity, and cosmetic use. The study found that facial creams (83.1%), lipstick (52.2%), eyeliners (54.7%), mascara (33.1%), eyelashes (12.5%), eyeshadow (16.1%), and foundation (15.6%) were the most commonly used cosmetics. Usage was mostly occasional (63%) or daily (37%), with 88% preferring daytime application. Significant associations were found between age and usage purpose (p=0.043), and between ethnicity and choice of cosmetics (p=0.030). Reported side effects included acne (23.3%), bleaching (25.7%), pigmentation (12.2%), rashes/itching (13.9%), irritation (5.2%), skin hardening (4.5%), and other complications (15.3%). Eye-related issues included redness (52.2%), itching (20.2%), soreness (15.4%), puffiness (3.5%), and miscellaneous problems (8.8%). Lip problems were primarily cracking (70.8%), swelling (16.9%), and bumps (12.3%). In conclusion, the use of facial cosmetics is prevalent among students, mainly for occasional use and primarily during the day. The purpose of cosmetic use varies with age and ethnicity. The most common side effects are skin pigmentation, eye redness, and swollen lips.
