The difference between physical sunscreen and chemical sunscreen. In fact, sunscreen is also very particular.

Many people think that sun protection is only needed in summer. In fact, your idea is completely wrong. Sun protection is something that should be done all year round. Moreover, sunscreen is divided into two types: physical sunscreen and chemical sunscreen. Do you know the difference between physical sunscreen and chemical sunscreen? Let’s take a look together.

The difference between physical sunscreen and chemical sunscreen

Physical sunscreen works by reflecting sunlight and ultraviolet rays that reach the surface of the skin away from the skin, while chemical sunscreen uses energy conversion. The main ingredients are titanium dioxide and zinc oxide. The main ingredients of chemical sunscreen are chemical sunscreens. It is suitable for all skin types, but its disadvantage is that it has a thick texture and appears white and greasy after application.

How to apply sunscreen

Scientific research has shown that the dosage of sunscreen is generally 2 mg/cm2 to achieve the best sun protection effect. In layman's terms, when applying to the entire face, the amount used is about the size of a one-yuan coin. Apply sunscreen on the chin, cheeks, forehead, pen tip and other parts, then spread it evenly and gently. If you are applying sunscreen on your body, you can directly apply it in a straight line and apply it evenly using circular motions.

Sunscreen product recommendations

Mentholatum New Clear Water Thin Sunscreen

Sun protection index: SPF30 PA++

The texture of this sunscreen is white lotion, and it is neither thick nor thin, just the right touch. After applying it on the face, it melts quickly on the skin. There is no process of changing from white to dark white. It also has no sticky feeling and is very refreshing. However, the sun protection strength of this sunscreen is not high, so it is recommended for white-collar workers who often sit in the office to apply it.

Biore Water-Based Sunscreen

Sun protection index: SPF50 PA+++++

I believe many people have been using this Biore sunscreen since college, and it updates a new version every year. Its texture gives me a refreshing feeling. It is not greasy or dry after applying on the face. The moisturizing effect is still good.

Allie High-Efficiency Sunscreen Lotion (Green Tube)

Sun protection index: SPF50+ PA++++

This sunscreen has a light yellow gel texture and is thicker than the Biore one. After applying it on the face, it feels refreshing, moisturizing but not greasy, and has a moisturizing effect. It also has very good ductility and is easy to push open without rubbing against mud.

Anessa Gold Bottle (New Version)

Sun protection index: SPF50+ PA++++

The old version of Anessa may feel a bit greasy to use, but the new version has mineral oil added, so it is relatively refreshing to use. The texture is white lotion with a slight alcohol smell. The film forming speed is very fast, and the new version of Anessa does not require makeup removal, you can just wash it with facial cleanser.

Lancome Air Sunscreen

Sun protection index: SPF50 PA+++

This sunscreen from Lancome has a hydrogel texture. It quickly dissolves into water on the face and is very light, so you can’t feel that you’ve applied any sunscreen at all. Moreover, this sunscreen uses patented Mexoryl technology, which can effectively protect against UVA and visible blue light. It not only prevents darkening but also photoaging. We must not slack off on sun protection. In order to avoid aging so quickly, in addition to skin care, sun protection is definitely a very effective way. I hope everyone can still maintain a youthful face when they reach middle age.
