What is the difference between sunscreen spray and sunscreen? How to choose the right sunscreen?

The main cause of skin aging is ultraviolet rays. Under long-term exposure to ultraviolet rays, the moisture of the skin will be lost, the skin will become dry, fine lines will easily appear, and the skin will become darker. The correct use of sunscreen can prevent ultraviolet rays from damaging the skin, reduce skin damage caused by sun exposure, and protect the skin. There are two main types of sunscreens commonly used in life, one is physical protection type and the other is chemical protection type. Regardless of which type of sunscreen, the SPF factor above cannot be ignored. The higher the sun protection score, the longer the protection against ultraviolet rays will last. Therefore, girls who love beauty must apply sunscreen all year round and look at the sun protection index, so that our skin can always be beautiful! Today I will introduce to you the knowledge about sunscreen.

What is the difference between sunscreen spray and sunscreen

Sunscreen spray and sunscreen cream have different textures. Sunscreen cream is in a water-like state and is suitable for dry and combination skin. Sunscreen spray has a very light and clear texture and is suitable for oily skin. The two are also used in different ways. Sunscreen cream is applied directly to the facial skin, while sunscreen spray is sprayed on the face.

Sunscreen is generally divided into physical sunscreen and chemical sunscreen. It has the function of correcting skin color. It contains more skin care ingredients, and its moisturizing and nourishing degree are much better than sunscreen spray.

Sunscreen spray is a chemical sunscreen, generally with an oil-free formula. It is more practical for people with acne or sensitive skin on the face. The liquid spray does not feel sticky and has better water resistance.

Sunscreen spray is mainly suitable for sensitive skin and oily skin. Sunscreen spray is relatively refreshing and will not burden the skin, thereby reducing oiliness of the skin.

At what stage should sunscreen be applied?

Sunscreen is applied at the last step of skin care. After applying lotion and facial cream, apply sunscreen evenly on the face. Wait until the sunscreen forms a film and is absorbed by the skin before using other cosmetics. There will be no mud on the face. It can also effectively prevent foundation from clogging pores and play a role in protecting the skin.

Sunscreen is applied as the last step in skin care. After using lotion and facial cream, apply sunscreen on the cheeks, forehead, nose, and chin. Gently pat it with your hands to spread it evenly on the face. Wait for a few minutes until there is a thin, shiny film on the face before using other cosmetics.

After the sunscreen is formed into a film, it feels smooth and can be better absorbed by the skin, playing a role in skin care. When using other cosmetics, there will be no mud on the face, which can effectively prevent the foundation from clogging the pores. Sunscreen is not only used in summer, but also in other seasons. It can effectively prevent ultraviolet rays and protect the skin.

How to choose the right sunscreen

Look at the ingredients

There are three types of sunscreen: chemical sunscreen, physical sunscreen, and physical and chemical sunscreen.

Physical sunscreens achieve the sun protection effect through physical refraction and reflection of light. Common ingredients are zinc oxide and titanium dioxide.

Chemical sunscreen absorbs ultraviolet rays and converts light energy into heat energy on the skin surface through chemical reactions and releases it. There are many kinds of ingredients. Remember that all sunscreens other than physical sunscreens are chemical sunscreens. (That's how Lisa remembers it)

Look at the SPF value and PA value

SPF is the reflection of the ability to protect against UVB, in simple terms, it is sunscreen against sunburn. For example: if you do not apply any product, your skin will turn red after 1 minute in the sun, but after applying SPF30 sunscreen, your skin will turn red after 30 minutes in the sun. PA targets UVA, in simple terms, it is sunscreen against tanning. Like SPF, PA is also a mark of protection ability.

Look at the packaging volume

50g can be used up within one month if used daily, 75ml can be used up within two months, and 130g can be used up within two months if used daily. It depends on how long you use it. Sunscreen that is one year old cannot be used, and the shelf life is only half a year after opening. If it has never been opened, you can continue to use it.

Look at the oil content

As for oil content, it can only be a matter of experience. Oily skin is prone to oiliness, so it is more practical to choose a sunscreen with strong penetration, while dry skin should choose a sunscreen with higher hydration. For combination skin, you can decide whether you need more moisturizing effect or more sun protection effect.

See the use occasion

For military training, swimming, etc., choose SPF30 or above

Daily use: spf15 is enough.

Do I need to remove sunscreen?

First of all, it is necessary to remove sunscreen, because some sunscreens are greasy and contain solid sunscreens that will not dissolve in water but only in oil, so ordinary facial cleansers cannot dissolve them at all. If you do not remove makeup once or twice, your skin will not see any changes, but over time, the sunscreen will remain on the skin, causing clogged pores, acne and blackheads. In addition, how to use sunscreen correctly? First, clean your skin before using sunscreen, and then apply lotion. If you have dry skin, you can apply a layer of lotion after applying lotion, and then use sunscreen.

Second, the sunscreen must be applied evenly. Don't just remember the face and forget the neck, arms and other parts. Otherwise, you will find that everything except the face is dark, which is not good-looking! Don't forget behind the ears.

Third, sunscreen should be applied about 20 minutes before going out, because sunscreen is not effective as soon as it is applied, and it needs time for the skin to absorb it. And you need to reapply sunscreen after about two to three hours of going out. Finally, as I said at the beginning, sunscreen removal is necessary. If you want to have fair and flawless skin, it is important to use sunscreen correctly, so that we can be fearless of the sun!
