What are the functions of a barrier cream?
I have recently been learning about skincare. I heard that sunscreen (or a primer) is important, but I'm not entirely clear about its function. Could someone please tell me what the main uses of sunscreen (or primer) are? Does it really provide a barrier against makeup and polluted air?

Emulsion, also known as primer or sunscreen barrier cream, primarily serves to protect the skin, adjust skin tone, and enhance makeup effects in the field of aesthetic medicine.
Emulsion can form a protective barrier that helps the skin resist external environmental aggressions such as ultraviolet radiation and air pollution, reducing damage caused by these factors. Many emulsions contain color-correcting ingredients that can address uneven skin tone, such as redness, dullness, or pigmentation, making the skin appear more even-toned and radiant.
Emulsion can also adjust the skin's complexion and texture, providing a smooth and even base for subsequent makeup application. Additionally, it forms a protective barrier on the skin's surface, locking in moisture and preventing dryness and water loss. The silicone-based ingredients in emulsion can fill in fine lines and pores on the skin's surface, making the skin smoother and helping makeup adhere better and last longer.
Emulsion is an essential step in daily skincare, offering comprehensive protection and nourishment for the skin. In daily life, it is recommended to choose products suitable for your skin type and needs. A light diet is advised, avoiding spicy and irritating foods.
