If you stay in an air-conditioned room for a long time, your skin will become dry and greasy, and your whole body will become greasy. At this point, the skin needs to be hydrated. Moisturizing sprays are the choice of many because they are easy to use and carry.

However, some people think that moisturizing spray is an IQ tax and has no moisturizing effect.

So is moisturizing spray an IQ tax?

The main function of the moisturizing spray is to hydrate and moisturize dry skin, and play a role in hydrating and moisturizing. Additionally, some products have added calming ingredients. For sensitive skin, moisturizing sprays are effective, not IQ taxes, as they hydrate and soothe the skin over time.

However, if used incorrectly, it may not work well and the skin may become dry. It is best not to just spray the moisturizing spray on the face, but evenly spray it 10 to 15 cm away from the face.

After spraying, leave it on the face for about 1 minute, then wipe off excess moisture with a tissue to stabilize and soothe skin.

When is the best time to use a moisturizing spray?

Moisturizing sprays have no set time of use, as long as they are used properly, they can be used any time the skin feels dry.

Most people are likely to go to work or something else right away after hydrating with a moisturizing spray, but a lotion is recommended if possible. Moisturizing sprays temporarily leave moisture on the skin, which will disappear quickly, so use a lotion at the same time to keep your skin hydrated.

If you are wearing make-up, you should set your makeup with a setting spray or powder after your moisturizing spray.

What is the principle of moisturizing spray?

Inert gas is added to the bottle, and water mist is sprayed by gas pressure during use.

In fact, this principle can be done by most people. We also know that the key to moisturizing spray is not necessarily the ingredients, but the water mist sprayed out.

The skin is divided into stratum corneum, transparent layer, granular layer and basal layer. To provide sufficient moisture, moisture must penetrate into each layer.

However, because our skin has strict requirements on the absorption size of water molecules, generally water molecules can only reach the stratum corneum at most. Like some untreated water, they belong to macromolecules and are not absorbed by the skin.

This explains the first question, why can't you just shoot the water directly or spray it with a small watering can?

The answer is of course no. In addition to following the principle of air pressure, moisturizing spray uses technical means to adjust the bottle body, nozzle and other parts to reduce the size of the spray molecules, so that the water molecules can ensure that the size of the molecules sprayed from the spray is as small as possible, and is The skin absorbs well.

Secondly, we must consider the actual existence of "water". In fact, water is the most basic solvent. It is very common in skin care products, but it is not necessarily pure "water", but is collectively referred to as "water". With a variety of water sources, including Alpine Mineral Water and St. Odile Spring Water, it is a very basic ingredient in a moisturizing spray, offering unique effects and selling points.

So don't underestimate this water and simply assume that tap water in your home has the same effect.

If you have your own requirements for efficacy, you can choose a spray product with more skin care ingredients. In addition to secondary moisturizers like hyaluronic acid, there are mild sedatives like purslane and chamomile.

Also remember that there are two different spray types when choosing a moisturizing spray

[Aerosol foam]

Use special packaging, cylinders filled with "nitrogen", "carbon dioxide", etc. In this way, the influence of external stimuli, microorganisms, etc. on the spray material can be avoided. Therefore, this spray requires no added preservatives, and most of the ingredients are relatively simple.

[Pressure pump type]

This spray has no aerosol packaging material, is cheap, and has a slightly less effective spray.

However, with the advancement of technology in recent years, the nozzles are getting better and better. However, such sprays often contain preservatives and skincare ingredients due to the limitations of hand-packed packaging. Of course some use antibacterial technology to avoid the use of preservatives, it depends on the product you choose.
