Tretinoin cream 0.1% is particularly a form of Vitamin A that helps treat pimples, and acne by detoxing the pores of your skin. It further helps prevent pimples and acne spots from appearing in the future. It usually takes several weeks to have a noticeable result, so it’s highly recommended to use this cream with patience. In some users, acne may get worse before it completely gets cleared. The earlier you start using this medicine, the fewer scars are left behind.
