In the evening, after applying toner, I apply this serum by massaging it into my face and then gently patting my cheeks. I use it every other day, alternating it with other serums, including Caryophy Portulaca Ampoule and Care:Nel Niacinamide 10% Zinc 1%. I use the same amount and apply it the same way as the other serums, so I don’t understand what’s going on.
