The difference between cold spray and hot spray

Cold spray and hot spray are two common outdoor sunscreens. The main function of cold spray is more suitable for people with sensitive skin, because it will not irritate the skin, and can reduce the damage to the face. It can also calm the skin, kill bacteria and reduce inflammation. Hot spray is more suitable for dry skin and oily skin, which can promote pore metabolism and replenish moisture to the skin.

The role of cold spray and hot spray on the face:

1. The role of cold spray

1. Cold spray is more suitable for people with sensitive skin, because hot spray on sensitive skin will irritate the facial nerves, while the cold spray of the facial steamer is less irritating, can lower the temperature of the skin surface, and has a calming and anti-inflammatory effect.

2. The effect of cold spray is to calm the skin, kill bacteria and reduce inflammation, and it can also lighten skin spots. And because of the temperature, cold spray can shrink the skin and tighten the skin when sprayed on the face. Persistent use of cold spray on the face steamer can inhibit the production of melanin in the skin and has a good effect on lightening dark spots on the skin surface.

3. The use time of cold spray can be up to twenty minutes. Because cold spray is gentler and safer than hot spray, the use time of cold spray can be slightly longer.

4. Cold spray is more suitable for use in summer, especially after being exposed to the scorching sun outdoors in summer. Using a facial steamer to spray cold water can calm and soothe sunburned skin.

2. The role of thermal spraying

1. Thermal spray is more suitable for dry skin and oily skin, because when people with dry skin use thermal spray, the ionized steam contains a large amount of oxygen ions, which can increase the temperature of the skin surface, accelerate skin microcirculation, and provide the skin with sufficient moisture and nutrients. For oily skin, using a facial steamer to spray hot water can soften epidermal cells, expand pores, promote skin metabolism, and remove excess oil from the skin.

2. The effect of thermal spray is efficient hydration and deep cleansing. Because the temperature of thermal spray is relatively high, it can help the skin open the pores, allowing more water to be absorbed by the skin. It can also promote skin metabolism, discharge oil and dirt in the pores, and make the skin become hydrated and rosy.

3. The general usage time of hot spray is about 8-10 minutes. Steaming the face for too long will cause damage to the skin, and symptoms such as pale and dry face will appear.

4. Hot spray is more suitable for use in winter due to its heat and moisturizing effects. It can not only replenish moisture for dry skin in winter, but also soothe tight skin. Although hot spray of facial steamer can also be used in summer, the effect will be more obvious in winter.
