Please inquire
น้ำหอม sold in bescents can be mixed in every face cream? That the amount of use: Lotion, Cream, Gel, Serum: 0.1-0.5% Perfume: 5-15% but
น้ำหอม some do not have instructions, can be mixed in cream. Is it the same? The way to mix in the cream is to mix it in the last step or dissolve it in water. Used to mix the cream. Thank you.
