[|Human|] hi ! i have wheatisChatDoctorplexion .i used cosmelite and it helped me to become fairer.i am using regular sunscreen.but my skin becomes darker when i stop to use cosmelite and also in winters. i want to ask should i need to use cosmelite for lifetime.
[|AI|]  Hello Kristi, welcome to Chat Doctor.I will be glad to be of assistance. Cosmelite cannot be used lifelong. In fact, it should be used for a maximum of 3-4 months not more than that. I will recommend that you use glycolic acid 6% cream on full face every night. That will also cause evening out of your skin tone and a bright complexion. The sunscreen has to be reapplied once every 4 hours. That will ensure good efficacy of the sunscreen. Hope my recommendations are useful to you. Please let me know if you have any queries.
