As far as our experience with cosmetics is concerned, dark glass bottles give us a more high-end feeling.

The principle and advantages of dark glass bottles

Like to use dark glass bottles as packaging for many products, such as "small brown bottles", "small black bottles", "red waist" and so on, so what is the reasoning behind this?

The role of dark glass is to block the UV rays of the sun to avoid the oxidation and decomposition of some photosensitive active ingredients. Generally speaking, antioxidant, anti-aging, whitening, and other such highly active skincare products, will choose dark glass bottles to hold. For example, vitamin C, ferulic acid, polyphenols, and other ingredients are easily oxidized when exposed to air or light; retinol and its derivatives are chemically unstable and easily decomposed by UV rays. These active ingredients are the soul of each skincare formula, once the photolysis of oxidation will have little effect, and some ingredients may even be toxic or allergenic after photolysis. The previous also said that the glass container is light and heat resistant, so this type of skincare product to choose dark glass bottle is particularly necessary. This truth is actually the same as red wine, storage protection is not good, even if it is 82 years of Lafite can only be poured in the end.

What are the reasons for adopting vacuum packaging for cosmetic glass bottles?

I would like to ask you, choose skincare products, you like the pour-out type? Or squeeze it? Or press type it? I believe most people will choose the pressed pump head design because it makes it easier for us to access cosmetics and is more hygienic in the process of use. It is no wonder that we prefer the pressurized pump head design, there is some scientific basis for this.

With a pressurized pump head design, you are actually preserving your skincare products in a vacuum environment. The principle of vacuum pump head design for skincare products is to use the retraction force of the spring to keep air out of the bottle and create a vacuum, thus achieving the result of "out and out" use. Each time the pump head is pressed, the small piston at the bottom of the bottle moves up, so that no air enters while the material comes out, and as the material decreases, there is less and less space, so that a product does not have to worry about air entering from the time it is opened to the time it is used up.

The advantage of this design is that it can prevent the product ingredients from being oxidized and stabilize their activity. In addition to this, it also inhibits microbial reproduction and growth to a certain extent, avoiding contamination. This replaces the addition of any preservatives and preservative-like agents and allows the product to maintain a stable formulation during use. It is reasonable to assume that the vacuum pump head is designed to extend the storage time of cosmetics, but most skincare products are liquids, such as moisturizing water and lotions, and it is impossible for such liquid products to be completely vacuumed like solids, so the extended preservation time is limited.

After all, most skincare products are too precious to see light and too hot to be subjected to heat, so a little carelessness will cause changes in the composition of the cosmetics.
