Can sunscreen replace isolation? What is the difference between sunscreen and isolation?

Some people say that if you apply sunscreen, you don't need to apply primer. Is that true? Can sunscreen replace primer? What is the difference between sunscreen and primer?

Sunscreen cannot be used as a barrier, as there is no barrier effect in sunscreen. Sunscreen and barrier cream are actually two different products. The function of sunscreen is to protect the skin from ultraviolet damage, while the function of barrier cream is to isolate the skin from the outside world, such as dust, cosmetics, and computer radiation.

1. The functions of sunscreen and isolation cream are different.

The main function of isolation cream is to isolate dust, oil, makeup and radiation. Some isolation creams have SPF and UV index, which are additional sun protection or radiation protection functions. But sunscreen only has sun protection function, which is divided into physical sunscreen and chemical sunscreen.

2. Sunscreen and isolation cream have different uses.

Sunscreen only has the function of sun protection. In addition to the sun protection function, isolation cream also contains antioxidant ingredients, whitening ingredients or vitamin ingredients. Compared with ordinary sunscreen, isolation cream has purer ingredients, is easier to absorb, and can prevent dirty air and ultraviolet rays from damaging the skin.

3. The order of using sunscreen and isolation cream is different.

Use primer first and then sunscreen, this order cannot be changed.

No.1: Olay Zero Gravity Small White Umbrella

When it comes to sunscreen brands, the first thing to mention is Olay Zero Gravity White Umbrella. The moisturizing essence milk texture will instantly turn into water after being applied, and the touch is the same as the lotion that fairies usually use. The skin after the film is formed is visually very pleasing to the eye, slightly brightened, thin skin is water-permeable, and has a light and high-end luster. It will form an invisible protective film on the skin surface, but it is very breathable.

In addition to Olay's signature ingredient - 99% niacinamide, the Zero Gravity Little White Umbrella also contains trehalose and active white tea extract, which can protect against the sun, while also providing antioxidant and moisturizing effects. It can block ultraviolet rays while reducing damage to the skin.

No.2: Kiehl's All-Way Sunscreen

This sunscreen has a moist and easy-to-spread lotion texture, strong fluidity, and is very smooth to apply. Although the sunscreen uses an oil-free formula, it is basically not dry when used, and the face is moisturized after application. The sunscreen itself does not have any color, so fairies do not have to worry about fake face or affecting the subsequent foundation.

This sunscreen from Kiehl's has a clear Daily logo on it, and the formula is indeed reassuring, so people with sensitive skin who are struggling to decide which brand of sunscreen is good can use it with confidence. In addition, rose flower extract and VE are added to the sunscreen to achieve the effect of anti-oxidation and moisturizing the skin.

No.3: Ultrasun sunscreen

The ingredients of this sunscreen can be said to be extremely simple. It does not contain any controversial ingredients, nor does it contain fragrances, preservatives, silicone, mineral oil and other acne-causing formulas. It is extremely gentle and is a sunscreen that pregnant mothers can use with confidence.

The sunscreen forms a film quickly, does not rub mud or white flakes, and is waterproof and sweat-proof. Fairies who don't like the cumbersome skin care and makeup process can directly use this sunscreen instead of cream, and then apply a layer of loose powder and go out quickly. There is no need to use additional makeup removers, and ordinary cleansing can clean it very well.

No.4: La Roche-Posay Big Brother Sunscreen

In addition to its shape resembling a big brother, the sun protection power of this sunscreen is as hardcore and reliable as the big brother.

The texture of the old version of sunscreen is a bit thick, and the oily film is also obvious, which is the traditional high-factor sunscreen skin feeling. However, the texture of the upgraded new version this year can be said to be "reborn". It is very thin and can be evenly applied with just two strokes. The texture is basically close to water. In this season, it is still worth a try for oily skin.

No.5: ALLE Water-Free Sunscreen

The gel-textured sunscreen is not greasy at all after applying on the face, refreshing and burden-free, and has the effect of slightly brightening the facial skin tone. Therefore, I often use it as a primer, and the subsequent base makeup will fit better.

Regarding the usage of this sunscreen, the editor would like to emphasize that the correct way to use it is to apply it on the face first and then gently pat it open. Note that it should be patted open, not smeared or rubbed. It is just like applying liquid foundation. Wait for the film to form before continuing to apply the base makeup, so that it will not be rubbed into mud.

No.6: ST Big Black Umbrella

The silicone + polyol base configuration makes the skin feel silky and smooth. The entire process of applying it on the face is more like applying lotion, similar to Olay Zero Gravity Little White Umbrella. The sunscreen is almost colorless when applied, and it basically becomes transparent after forming a film, without any film feeling. The Big Black Umbrella has a very obvious effect on modifying pores. When applied on the face, it feels like the pores are filled. I am sure you are a mother of large pores.

No.7: Ampleur small white umbrella

Its texture is a classic Japanese sunscreen lotion texture. It is very moist after being applied, and it does not turn white. Moreover, it forms a film very quickly, and you can almost wait for it to form a film. After forming the film, it is not oily and does not dry out. No matter how many layers I stack, it is dry and light.

It is officially announced that it is a "three-protection" sunscreen - protection against ultraviolet rays, protection against PM2.5, and protection against blue light. For sisters like me who use electronic devices for a long time, this sunscreen brand is perfect.

No.8: Aishiti Small A Tube

As soon as you open the sunscreen, you can smell a fresh and healing rose fragrance. It can be used as daily sunscreen or as a primer. It is worth mentioning that the small A tube contains nano-astaxanthin, w-humanoid nano-ceramide and 3 types of collagen. It is rare for a sunscreen product to have such a rich content.

In addition, the small A tube also uses Aishiti's exclusive retractable UV protective film technology, which means that after the sunscreen is formed into a film, it can move and extend according to the changes in the mask's expression, filling in the lines and gaps. Even when wearing makeup, it can ensure that this layer of protective film is firmly attached to the face.

No.9: heliocare sunscreen

This is a brand that specializes in sunscreen products, and it seems to be quite popular recently. It is a full-spectrum sunscreen that protects against the entire spectrum of solar radiation. With the unique sunscreen and antioxidant technology Fernblock, as well as VE, VC, and green tea extract added to it, it can fight free radicals with multiple antioxidants and improve various skin aging problems caused by light. To be honest, the fact that it can protect against the sun and provide antioxidants at the same time really touched the editor.

No.10: Biore Water Active Sunscreen Softening Gel

60 yuan for 60g, a must-have for slum girls. SPF30 PA+++, this sun protection index can basically meet the sun protection needs of girls in autumn and winter, but it is slightly insufficient for summer use. In addition, hyaluronic acid and a variety of citrus moisturizing extracts are added to the sunscreen, which can keep the skin moisturized for a long time. It is first-class moisturizing power among affordable sunscreens.

Generally speaking, the higher the SPF index, the greater the protection provided. Under normal circumstances, people with normal skin types should use sunscreens with SPF8 to 12; those with fair skin should use SPF30; those who are allergic to light should choose SPF values ​​between 12 and 20. Office workers are only exposed to the sun on the way to and from get off work, so an SPF of less than 15 is sufficient. Tourists who engage in outdoor activities are recommended to use sunscreens with SPF20 or so. When doing activities under the scorching sun on the plateau or swimming at the beach, it is advisable to use sunscreens with SPF30. When swimming outdoors, it is advisable to choose waterproof sunscreen skin care products, but waterproof sunscreen skin care products should be used less except for swimming.

For people with oily skin and prone to acne, they should choose lotion-like products that are refreshing and non-greasy. Never use sunscreen products such as sunscreen oil or isolation cream.

Assuming that the effective time of SPF15 sunscreen is 15 (minutes) x 15 (times) = 225 minutes. You can choose based on how much time you will be in the sun, and also based on your skin type. If your skin is mixed/mixed oily, then choose a lotion. If it is dry, choose a cream.
