How long can 15ml lotion be used and what is the difference between it and essence

Lotion can replenish moisture for the face. The skin on the face will not appear tight and peeling only when it is sufficiently hydrated. The face needs enough water, so you need lotion from skin care products. How long can 15ml of lotion be used? What is the difference between lotion and essence?

How long can 15ml of lotion be used?

There is no fixed time for this, and the amount of lotion used by each person is different.

If you use lotion every morning and night, a 15ml bottle of lotion can be used for 2 to 3 weeks. When it comes to 15ml, many people may not have any idea about it. 15ml of lotion is equivalent to a trial pack. If you are not sure whether a brand is suitable for you, you can buy their small sample first. If you find it suitable for you, then choose a large bottle.

Skin care products all have a shelf life. The shelf life of unopened skin care products is 3 years, while the shelf life of opened products is 6 months or one year. The best use time is 6 months. The shelf life of opened skin care products is usually marked on the bottom of the bottle. 6M or 12M means that the best usage time after opening is 6 months or 12 months.

After opening, skin care products need to be used every day, and bacteria will enter the bottle. If there are too many bacteria, the skin care products will easily deteriorate. Skin care products that contain a lot of bacteria can easily cause facial allergies when applied on the face.

When buying skin care products, it is better to buy bottles with smaller mouths. The larger the mouth of the bottle, the faster it will deteriorate.

The difference between lotion and essence

1. Water emulsion

The main function of lotion is to moisturize. The texture of the liquid is relatively thin, and the molecules are relatively small, so it is very easy for the skin to absorb.

After cleansing your face with cleansing products, you should apply water to your face, then apply essence, and then lotion. Lotion can lock moisture into the skin, while makeup can hydrate the skin and soften the cuticle. Lotion is a liquid cream that has a very good moisturizing effect. Can be used morning and night.

Different seasons require different lotions and emulsions. Highly moisturizing lotions and emulsions are suitable in autumn and winter, while moisturizing lotions and emulsions are suitable in spring and summer.

2. Essence

Essence is functional, it has anti-aging, whitening and moisturizing effects.

The texture of essence is also relatively light, but its concentration is higher than that of lotion and its molecules are relatively large. Except for whitening essence, they can be used morning and evening.

Whitening essence is only suitable for use at night. It contains photosensitive ingredients and is not effective when used during the day. The whitening ingredients in it will be eliminated by ultraviolet rays and the whitening effect cannot be achieved.

Although essence has antioxidant effects, it cannot be used alone as the skin cannot absorb it. It needs to be used in combination with lotion and lotion.

15ml of essence is equivalent to a small sample. To test whether a product is suitable for you, you can buy a small sample to start. There are still differences between essence and lotion. There are still differences in concentration, efficacy, and usage time.
