Cold water wash pores? Some skin care rumors can't believe

Gossip 1: cold water wash can shrink pores

Once the skin temperature returns to normal, the pores will be returned to the original shape. In addition, too cold water can block the transport of nutrients in the epidermal cells, leaving the skin with no nutrients. In addition, hot water control oil is also incorrect, because the overheated water will wash away excess oil on the face, making the skin easy to dry, and then stimulate the secretion of oil.

Therefore, this step of cleansing in the morning can not be omitted. It is necessary to remove all kinds of dirt by washing and cleaning, so that unwanted skin metabolites are no longer left on the face. In addition, the skin after washing the face in the morning quickly returns to a good state, so that the cosmetics used next can exert the maximum effect.

The correct approach:

To clean your face in the morning, you don't need to use a product that is too clean, just use a gentle system.

But the effect of the lotion can be fully realized, and the correct method of use is king.

Correct practice: Use according to the efficacy and use of the lotion.
