How to identify the authenticity of fresh aloe vera gel

Aloe vera gel is something that everyone is very familiar with. There are many different brands of aloe vera gel on the market. Many people do not know how to distinguish the authenticity of aloe vera gel. Only if you buy authentic aloe vera gel can you achieve good repairing and moisturizing effects. Otherwise, it will have no effect at all and may even cause greater damage to your skin. Everyone must choose and identify carefully and buy it in regular places.

Experimental method

Good aloe vera gel is very pure and viscous, and its fluidity and permeability in water matrix are relatively poor. Apply a bean-sized amount of aloe vera gel on a piece of paper, place it vertically, and observe its flow and penetration speed. The faster the penetration, the more water it contains. If you feel obvious water flowing out as soon as you take it out, then the moisture content is basically very high. At the same time, the faster the flow, the lower the aloe vera gel content indirectly.

Look at absorption

Aloe vera gel with good absorption speed ensures the high molecular weight and high activity of aloe polysaccharides and glycoproteins, without adding water, so it is smooth, refreshing and quickly absorbed. The faster the absorption, the more active the active ingredients are and the higher the content. I tried the Aloe Vera Gel from Aloe Vera. I applied a thin layer and it was completely absorbed in 10 seconds. After a lot of aloe vera gel is spread on the skin, it is basically water, so the absorption is very slow. Water-soluble compounds are not easily absorbed by the stratum corneum, the outermost layer of the skin. Most of it evaporates into the air. This Korean product takes more than a minute to be absorbed when applied on the hands, and it will feel sticky after use.

Color

Look at the color and transparency. High-quality aloe vera gel is made completely from purified aloe vera gel. Aloe vera gel made from fresh aloe leaves is usually "beige" in color with a slight turbidity (translucent). It is not colorless and transparent. Completely transparent aloe vera gel is usually made of dry powder or contains very little or even no aloe vera gel. Some aloe vera gels are light yellow. The light yellow color means that the texture is impure and other ingredients may be added. It also means that the ingredients may be oxidized. Transparent jelly can often be made by simple synthesis of water and carbomer (gelling agent).

Look at the degree of absorption

The main ingredients of high-quality aloe vera gel products are aloe polysaccharides and glycoproteins. Relatively pure aloe vera gel is absorbed very completely, and if used correctly it will not cause rubbing into mud after use as many consumers have reported, which means it does not need to be washed. There will be no solidified residue. Some so-called aloe vera gels contain a large amount of chemical moisturizing ingredients and anti-inflammatory repair substances. Some of these substances are almost unable to penetrate the epidermis and cannot be absorbed by the skin, so they are easy to remain, resulting in incomplete absorption, very sticky hands, and often rubbing into mud! Therefore, these so-called aloe vera gels must be washed off after use, otherwise it will affect the skin's breathing.
