Every year, we have taken comprehensive UV protection measures, but we still suffer from long spots, dark and uneven skin color. This is mostly due to the wrong sunscreen application method. This HB Health&Beauty will solve the above skin problems for everyone.
Ms. Yomiko Sasaki, a senior beauty scientist of SK-II, said: "Research shows that nearly 80% of skin damage is caused by the environment." The most important environmental factor is the increasingly strong ultraviolet rays in summer.
Ms. Sasaki said, "There are reports that, In areas with high ultraviolet radiation and low contrast radiation, skin damage evolves rapidly and faster 。 In addition, the infrared ray, which is longer than the ultraviolet wave, has weak energy, but will accumulate damage in the skin over time, which is the cause of skin problems such as relaxation. ”
In order to prevent skin aging, we must fight against adverse environmental factors and protect the skin. Sunscreen products that have improved their efficacy year by year also have the function of anti-aging.
However, Professor Maeda Xianshou from the Department of Applied Biology of Tokyo University of Technology added: "There is a ratio between the anti ultraviolet effect and the amount of application. The SPF and PA used to express the sun protection index refer to the value of 2mg product applied to the skin every 1 square centimeter. In fact, Most people only apply 1/4 of the standard value 。”
On the basis of moisturizing in advance, it is essential to use the correct amount of product and apply it evenly to the whole skin. In addition, it is the secret of prolonging the effect to place it for 5 minutes after application to make the sunscreen products fully fit.
These skin enemies actually exist outside!
ultraviolet rays It is shortwave UVB that causes color spots and dullness. Long wavelength UVA is the cause of long-term fine lines and relaxation. Professor Qiantian said: "UVB has a greater impact on skin aging. It is important to take sunshade and other anti sunlight measures when going out.
Substances in the atmosphere PM2.5、 Car exhaust and urban dust adhere to the skin and accumulate, which will cause deep damage to the skin. These damages penetrate into the muscle surface, causing rough, dry, dull skin and other problems, and even causing skin damage such as spots and fine lines.
Infrared blue light The research on the influence of infrared light and blue light with longer wavelength compared with ultraviolet light on skin is also in progress. Although not as harmful to skin as ultraviolet rays in a short time, they are the cause of promoting aging in the long run, so it is important to take necessary countermeasures.
The environment will also affect the incidence of color spots and fine lines
The blue area is the area A with low UV throughout the year, compared with the area B (pink area) with high UV radiation (1.25 times the sunshine and 1.5 times the UVB). The figure shows that the incidence of color spots and fine lines is higher in B area.
Environmental factors can cause such changes in skin state
The left picture shows the skin with more environmental attacks, and the right picture shows the skin with less environmental attacks
A simulated portrait of aging skin of people aged 50 on average. Even at the same age, skin damage will increase with environmental factors such as ultraviolet ray, infrared ray, air pollution and so on, as well as color spots, fine lines and dullness.
Are you doing this inadvertently? Misunderstanding of UV nursing
Inadequate moisturizing will reduce the skin's protective function and weaken the ability to resist UV damage.
The UV protection effect is proportional to the application thickness of sunscreen. Don't save the amount of paint just because you don't like it very thick.
The reason for uneven application is that the sun block is applied forcefully. Friction stimulation may also cause the risk of pigment precipitation.
After applying sunscreen, immediately apply base makeup and wipe it off when applying makeup, which is not uncommon.
'I obviously have good sunscreen'. But actually......
According to the survey. Use the same kind of sunscreen lotion to confirm the UV fluorescence image after application according to the normal application method. Although I didn't realize that there were many cases of thin or uneven coating.
The part with thick color indicates the state of proper application. Emergent white The colored area is the thinly painted part or the uncoated state.
The first picture shows the correct state of evenly smearing on the skin surface with sufficient dosage. Although the second picture is painted evenly, it turns white because of the small amount of paint. This is insufficient application. In the third picture, the edges of the hairline and the sunken part of the eyelid are not evenly smeared.
Basic knowledge of sunscreen products
Sun Protection Factor is short for Sun Protection Factor, which mainly refers to the defense effect against UVB. It shows that the time from sunlight to sunburn can be extended by multiple through the use of sunscreen. To fight against ultra strong ultraviolet rays, only products with SPF value of about 50 can prevent inflammation caused by UVB of more than 50, which are specifically marked as [50+'.
It is the abbreviation of Protection Grade of UVA, which is used to indicate the UVA defense effect. It is based on the 'melanization (continuous instant melanization)' observed 2-4 hours after strong UVA irradiation. There are four stages from+to++++. The more+, the better the anti UVA effect.
It belongs to chemical sunscreen, which can absorb ultraviolet rays on the skin surface and reduce energy release. It contains protective components for UVA and UVB, as well as components to resist both wavelengths. Because it is a chemical reaction on the skin, people with fragile and sensitive skin will feel irritation, which is also one of the reasons for skin roughness. However, in recent years, the coating technology that can be directly used on the skin has been popularized, which can solve the above problems.
Composed of metal and clay powder, it can scatter and reflect the ultraviolet ray on the skin surface. The representative components are titanium dioxide and zinc oxide. Compared with UV absorbers, they have less burden on the skin. However, if the dosage is large, there will be a disadvantage of white printing color difference. However, with the evolution of particle size and surface processing technology in recent years, it is gradually improving.
In a variety of skin care products, the most rapid development is sunscreen products. In the past, if enough sunscreen is applied, there will be white marks, or products with high SPF value will easily cause various skin problems such as rough skin. However, with the improvement of UV absorber and dispersant processing technology, products that do not increase the burden on the skin and are easier to fit are gradually becoming mainstream.
On this basis, antioxidant ingredients can prevent the accumulation of skin damage caused by infrared and blue light, improve whitening and moisturizing effects, and support healthy skin in a more comprehensive way. The versatility of this UV protection and other skin beautifying effects is the feature of this season's new sunscreen products.
Most products, even if applied in sufficient amount, will not have a thick sticky feeling, light texture, and easier to fit. It is also important to reapply after sunscreen and makeup removal. Powder and spray sunscreen that can be directly applied on makeup is suitable for use when going out. Choose suitable products according to your skin status and living habits, and use them by category to protect your skin health.
