[Cosmetic Ingredients] Zinc Oxide & Titanium Dioxide - One of the Ingredients of Sun Care Products

A male friend once said to me that women are three big things: cosmetics, clothing and jewelry.

Yes, as the first "cosmetics", unlike clothing and jewelry, as visible, touch, as long as the use of reasonable, do not become a problem for decades, cosmetics, high prices, easy to consume, the percentage of profit hundred.

In cosmetics, facial care products are also eternal topics. It is worthwhile to conquer women’s wealth in the world.

Remover cleansing, hydrating, whitening, sunscreen, anti-aging, eye and lip care.

In order to better adapt to the current needs of everyone, the article “Cosmetic Ingredients Introduction” was launched with the active product of the recent sunscreen product.

Every summer is approaching, search engines will have a significant increase in search for keywords such as “Which sunscreen is good, sunscreen recommended, sunscreen ranking, what brand of sunscreen is good, and sunscreen choice”. Undoubtedly, the atmosphere and the environment are being destroyed more and more seriously. The ultraviolet rays that reach the ground directly have become more and more intense. For many women, with increasing age, there are more and more free radicals in the body, causing the skin to age gradually. This is "Inner cause", for internal causes, please eat more fruits and vegetables, and live a healthy life. The "external cause" of accelerating skin aging is, of course, the lethality of ultraviolet rays. If you haven't started sun protection, then you must act!

So many MM may be the first to ask, which brand of sunscreen is best used.

Here is to explain that in order to avoid the suspicion of small ads, not only this article, in any subsequent article, the author will not recommend any brand of products, just from the perspective of composition, for your reference.

Zinc oxide (Zinc Oxide) is an extremely common chemical additive. It is widely known to us and is generally used in pigments. It is called "zinc white". Look, it can already be used as a white pigment. Of course you can use it on your face because it will be more white! (Just a joke ^_^) Bai Guibai, it is painted on the face is completely white and sticky thick layer, regardless of viewing or use angle is not very pleasant.

The reason why zinc oxide is used as a sunscreen product is because it acts as an ultraviolet reflector and uses reflection to counteract two of our well-known culprits: UVA and UVB. UVB wavelength is 280-320nm, UVA wavelength is 320-400nm, and zinc oxide can just reflect the wavelength of 280-400nm ultraviolet light (data also shows 280-390nm), in any case, this band has been very long, with Titanium dioxide (Titanium Dioxide), they can achieve all UVB and UVA protection.

Titanium dioxide has a protective wavelength band of about 250-340nm. It is an excellent physical UVB protection agent, and it can also protect a part of UVA. Therefore, in general, the “physical sunscreen” products that people generally see will have these two kinds of sunscreen ingredients.

When it comes to physical sunscreen, you have to mention chemical sunscreen. In principle, physical sunscreen can achieve sunscreen by reflecting ultraviolet rays. Chemical sunscreen can be effective by absorbing dissolved ultraviolet rays, but don't blindly believe that the so-called "physical sunscreen is better than chemical sunscreen, physical The statement that sunscreen is less irritating, first of all, "irritant", is related to the substance contained in the product that causes stress reaction. Although the physical sunscreen agent such as zinc oxide and titanium dioxide has zero irritativeness, it is a sunscreen. , not all ingredients are physical sunscreen, at least it also needs to add solvents, emulsifiers and other ingredients, otherwise it is all powder it! And these additional additives have the possibility of sensitization caused by pox; in addition, pure physical sunscreen has a dead angle and needs to be compensated by chemical absorbents, so the physical and chemical sunscreen products currently on the market are the most effective products.

In addition, the common feature of both zinc oxide and titanium dioxide products is that they not only adsorb grease, but also absorb moisture. After use, they cause dry skin. Therefore, moisturizing before sun protection is essential.

So later, as long as you can see that Zinc Oxide and Titanium Dioxide are in the ingredients list of the same product, you can know that this product has a sunscreen component, but in the end this product is applied to the face. Whether or not it can play a role in sun protection depends on the specific content and concentration of the product (the order of cosmetics in Europe and America is ranked in descending order, but Japan is not). Sometimes, adding some sunscreen formulas is just to “help the product itself to sunscreen”, which is the same as whether the salt can be protected from radiation.

Laminate Lighting

A laminate lighting system is a special lighting technology used to provide lighting effects for display and display devices such as laminates and display cabinets. Laminates are usually made of transparent or translucent materials, such as glass, acrylic, etc., to display products or items.

Laminate lighting By installing lamps under or on the side of the laminate, the light shines directly onto the laminate, achieving the highlight of the display items and creating an attractive effect. Common lighting methods include:

Laminate backlight lighting: The light is installed behind the laminate, and through the transparency of the laminate, the item shows a bright and uniform effect under the illumination of the light. In this way, the display items can look more vivid and eye-catching.

Laminate sidelight lighting: The light is installed on the side of the laminate, so that the light comes in from the side, through the refraction and reflection of the laminate, evenly illuminating the display items. In this way, the texture and details of the item can be highlighted, enhancing its attractiveness.

Laminate point lighting: The use of small, high-brightness lamps to focus the light on a specific location to highlight the focus or specific part of the display item. This is often used to highlight a product or specific detail to create a unique visual effect.
