How long can the primer last? Can I use it without removing the primer?

The purpose of isolation cream is to isolate makeup and protect the skin. It also has a certain whitening effect. So how long can isolation cream last under normal circumstances? Can isolation cream be used without makeup removal?

About eight hours. Primer has the functions of whitening, brightening, and sun protection, but these effects are only temporary. They can make your skin whiter and brighter with just one touch. The duration of most primers is about eight hours, and the duration of each person's use of primer is different. In the final analysis, the duration of a bottle of primer is related to many factors.

Makeup remover is also needed for primer. Although it can isolate makeup and protect the skin from external irritation, primer still contains chemical ingredients. Therefore, if you do not use makeup remover to remove it, or only use facial cleanser to clean it incompletely, the chemical ingredients in it will clog the pores, which will not only cause enlarged pores, but also cause skin keratin to accumulate on the face, resulting in dark yellow and rough skin.

You can use a primer or BB cream in winter. Both primer and BB cream are cosmetics. The primer has the functions of sun protection, isolating dirty air, coloring, and adjusting skin tone, while the BB cream has the functions of concealing blemishes, adjusting skin tone, hiding pores, and protecting the skin. Both products can be used all year round and have nothing to do with winter. Therefore, you can use a primer or BB cream in winter.

It is OK to only apply primer. Primer can protect the skin from or reduce the damage of dust, light, radiation, and polluted air in nature and does not rely on any cosmetics. Different primers have different effects. For example, purple primer can modify the skin tone and achieve whitening effect, while green primer can cover red blood streaks. It is OK to only apply primer.
