Hello doctor! I am 26 years old this year, I don't know why at my age I have a slightly dry vagina and a bit of pain during sex. This has only happened recently. I went to the drugstore to ask and they gave me Kingphar's Spring Lady Beauty products. I don't know if it's okay to use these at my age and if it has any side effects in the future. Doctor can you help me? Thank you very much doctor!
