According to the description, after using Watson's olive series toner, muscle lotion and emulsion, I got up the next day and found that the pores on my cheeks became bigger. There are several possible reasons:

1. Improper use of emulsion: The coarse pores may be due to improper use of emulsion, which is not evenly applied to the face, but is too hard, thus irritating the skin and causing coarse pores.

2. Improper selection of emulsion: If the selected emulsion is not suitable for personal skin, it may cause pore blockage, resulting in large pores.

3. Improper use order: The use order of skin care products has a great influence on the skin. If you don't use it in the right order, if you don't use toner first and then emulsion, it may lead to the effect of skin care products not being fully exerted, and even irritate the skin, resulting in large pores.

It is suggested to choose appropriate skin care products according to individual skin types and use them in the correct order. If the problem still exists, it is recommended to seek the help of a professional dermatologist.
