[About the misunderstanding of 防晒霜]

It is generally believed thatSPF防晒霜 with a higher SPF value is better. Not so. SPF15防晒霜 can actually play 93% protection capabilities. (SPF30防晒霜 can play 97%< span class="s2">. Not a double difference.) ButSPFThe higher the value, the more The worse the permeability will be, the skin will not be able to breathe and secrete normally, resulting in a decrease in skin quality. Therefore, if it is not recommended in the case of particularly strong sunlight, you can consider a sunscreen with a lower valueSPF. Protects skin quality while sun protection.

2.[Go out with sunscreen]

防晒霜 is not immediately effective when applied. It usually takes 15-20minutes for 防晒霜 to be absorbed and fully functional. So do sunscreen at least 15 minutes before going out.

However, if it is a high-protection product that is both waterproof and sunscreen (an sunproof gold bottle), it is recommended that you must do the makeup removal procedure again.

I hope everyone can do a good job of sun protection in summer!
