Always use a gentle alcohol-free toner so that PH of the skin remain balanced.
Use lukewarm water to shower and wash your face and use gentle non-stripping cleansers so that the skin barrier remains healthy.
Stay hydrated by using heavier moisturizers but in case your skin breaks out very easily, or you still feel that your skin is oily, try to give hydration through lightweight serums which contains natural glycerin and Hyaluronic acids.
Never compromise on protecting your skin from harmful UV rays. The warm sun rays feel pleasant, but the UV rays can damage your skin a lot. Choose a sunscreen that has titanium dioxide or zinc oxide.
