The skincare I learned when I was younger was, cleanse tone and moisturize, that’s it. Nothing more and nothing less. Sometimes I even skipped the toner part due to that I felt more dry (probably used toners with alcohol in. The reason for alcohol in toner was probably due to being afraid of acne and thinking that that would be the solution.. ohhh my how wrong I was.. When I grew older I started using toner without alcohol and an eye cream. The toner I sometimes skipped. This is what I think is most common in the rest of the world (except Asia that is).
The second step after cleansing should be the use of a toner. Korean toners are packed with different substances that are beneficial for your skin. This is really not a step that should be skipped if you have any problems with your skin. After cleansing, the skin is quite sensitive and the toners bring nutrients back to the skin to protect it. Toners preps your skin for the next steps of your skincare routine. Many toners have the main purpose to hydrate the skin and this is of course important even if you have oily skin.
