When is the best time to use glycerin and what are the precautions for using glycerin

Glycerin is a commonly used moisturizer in winter. It can moisturize the skin when applied to it, but can glycerin be used at any time? There is also a saying that glycerin cannot be used during the day because it will cause the skin to darken after being decomposed by light. So, when is the best time to use glycerin?

When is the best time to use glycerin?

Glycerin is best used when your skin is dry

Because glycerin is hygroscopic, when used on dry skin, glycerin can absorb moisture in the air to moisturize the skin and form a moisture-locking film on the skin surface, slowing down the loss of moisture in the skin, allowing the skin to remain hydrated for a long time and improving dry skin.

Glycerin is best used when preparing for bed.

Our skin's absorption ability will be enhanced at night, so applying glycerin before going to bed can keep the skin moisturized all night, and help isolate the skin from external dust at night, keeping the skin clean. This way your skin will be hydrated when you wake up the next day.

Glycerin is best used when you are about to go out

Apply glycerin on your skin before going out. This can protect and isolate the skin, because glycerin can block some of the external environment's invasion for the skin, and can also prevent the skin from losing moisture too quickly due to wind. Using glycerin in winter can also prevent frostbite and frost cracking.
