"i&#039;m in my 30s and got cystic acne due to beauty medical treatment that stimulated my pimples. spoken to my cousin who is a dermatologist suggested me to use tretinoin cream at night which i tried last night 22.11.17 however i have tried and used so many products already and almost gave up until my mom&#039;s friend advised me to try crushed aspirin which i apply as mask on areas where i needed it and its a blessing coz its the only thing that actually works."
