Can sunscreen replace isolation? Which brand of sunscreen is good?

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

Can sunscreen replace isolation?

Sunscreen cannot be used as a barrier, as there are no ingredients in sunscreen that have a barrier effect. Sunscreen and primer are actually two different products. The function of sunscreen is to protect the skin from ultraviolet rays, while the function of isolation cream is to isolate the skin from the outside world, and can isolate dust, cosmetics, computer radiation, etc.

What is the difference between sunscreen and sunblock?

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

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

2. Sunscreen and isolation cream have different uses.

Sunscreen only provides sun protection. In addition to the sun protection function, isolation cream also contains antioxidant ingredients, whitening ingredients or vitamin ingredients. Compared with ordinary sunscreens, isolation creams have purer ingredients, are 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.

Which brand of sunscreen is good?

No.1: Olay Zero Gravity Small White Umbrella

When it comes to the best sunscreen brand, the first thing that comes to mind is Olay Zero Gravity Sunscreen. The essence has a moist texture and turns into water instantly after being applied, and feels just like the lotion that fairies usually use. The skin after film formation looks very pleasing to the eye, slightly brightened, thin and water-permeable, with a light and high-end luster. An invisible protective film will be formed on the skin surface, but it is very breathable.

In addition to Olay's signature ingredient - 99% niacinamide, the Zero Gravity 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 hardly feels dry when used, and the face feels moisturized after applying it. Sunscreen itself does not have any color, so fairies don’t have to worry about it appearing fake or affecting the subsequent foundation.

This Kiehl's sunscreen has a clear Daily logo on it, and the formula is indeed reassuring. People with sensitive skin who are struggling to decide which brand of sunscreen to choose can also use it with confidence. In addition, rose flower extract and VE are added to the sunscreen to achieve antioxidant and skin moisturizing effects.

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 off or fall off white flakes, and is waterproof and sweat-proof. Fairies who don’t like the complicated skin care and makeup process can directly use this sunscreen instead of facial cream, and then apply a layer of loose powder and go out quickly. There is no need to use additional makeup remover products, 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 feeling is more obvious, which is the skin feeling of traditional high-factor sunscreen. However, the texture of the new version upgraded 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 watery. In this season, it is still worth a try for oily skin.

No.5: ALLE Water-Free Sunscreen

This gel-textured sunscreen does not feel greasy at all after applying on the face. It is refreshing and burden-free, and has the effect of slightly brightening the facial skin tone. Therefore, I often use it as a primer, so that 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 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, and the entire application process on the face is more like applying lotion, similar to Olay Zero Gravity Little White Umbrella. The sunscreen is almost colorless when applied, and becomes basically transparent after forming a film, without any film feeling at all. The big black umbrella has a very obvious effect on modifying pores. It feels like the pores on the face are filled when applied. People with large pores are definitely my favorite.

No.7: Ampleur small white umbrella

Its texture is a very classic Japanese sunscreen lotion texture. It is very moist after being applied and does not turn white. Moreover, it forms a film very quickly and you don’t have to wait for it to form a film. After forming the film, it is neither oily nor dry, and it feels dry and light no matter how many layers I stack.

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 scent. It can be used as daily sunscreen or as a substitute for 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 rich ingredients.

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 the entire spectrum of solar radiation. Coupled with the unique sunscreen and antioxidant technology Fernblock, as well as the VE, VC, and green tea extract added in it, it can provide multiple antioxidant effects against free radicals and improve various skin aging problems caused by light. To be honest, the fact that it can provide sun protection and antioxidant effects really impresses 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 girls' sun protection needs in autumn and winter. If used in summer, the protection is slightly insufficient. In addition, hyaluronic acid and a variety of citrus moisturizing extracts are added to the sunscreen to keep the skin hydrated for a long time. Its moisturizing ability is first-class among affordable sunscreens.

What is the appropriate sun protection value of sunscreen?

Generally speaking, the higher the SPF index, the greater the protection provided. Under normal circumstances, people with normal skin should use sunscreen with SPF8 to 12; those with fair skin should use SPF30; and those who are allergic to light should choose an SPF value between 12 and 20. Office workers are only exposed to the sun on their way to and from get off work, so a SPF of 15 or below is sufficient. For tourists who engage in outdoor activities, it is recommended to use sunscreen with SPF 20 or so. When you are under the scorching sun on the plateau or go swimming at the beach, it is advisable to use sunscreen with SPF30. It is advisable to choose waterproof sunscreen skin care products when swimming outdoors, 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 SPF15 sunscreen is effective for 15 (minutes) x 15 (times) = 225 minutes. You can choose based on how much time you will spend in the sun, and also based on your skin type. If your skin is mixed/mixed oily, choose a lotion. If it is dry, choose a cream.
