This is a very basic rule for skin care: Cleanse, exfoliate, tone and moisturise. It’s not necessary to exfoliate daily as over-exfoliating causes more problems such as breakouts and dry skin. Once or twice a week is fine. It is also not necessary for everyone to use toner, depending on your skin type (consult your dermatologist if unsure). Use a moisturiser with an SPF for the day and one that is richer for the night.
