Nowadays, male friends are paying more and more attention to their health care skin care. However, when choosing male skin care products, it is inevitable to worry about choosing "toxic" skin care products. Here are a few tips to help you stay away from "toxic" skin care products when you buy.
1 with PH test paper to buy facial cleanser
The skin of the human body is weakly acidic. There is a weak acid film on the surface of the skin. If it is destroyed, the skin will become fragile and cause many skin problems, causing the bacteria to grow in an alkaline environment. Therefore, the use of a weak acid facial cleanser is very helpful for cleansing the skin. How to check if the cleansing product is alkaline? A PH test paper can solve the problem. Apply a small amount of product to the test paper. If the test paper turns dark green after a few minutes, it indicates that the substance has too much alkaline component.
2 creams in the fire know the pros and cons
Face cream is an important part of our daily care. It provides adequate nutrition to the skin and forms a protective film to prevent moisture evaporation from the skin. Many products on the market contain a small amount of mineral oil that is allowed to be added internationally. Mineral oil is a product of petroleum refining to form asphalt and re-refining bitumen. Its function is to lock moisture from the skin surface, but once the mineral oil exceeds the standard, Oily clogging pores, and skin problems such as peas and dark spots are endless. There are also good ways to detect creams. Take a small amount of cream on the spoon and heat it with an alcohol lamp or candle. The product that meets the standard will be like the state of milk boiled. The taste will not change and it will be more intense. If there is splashing, smoke, smoke, smell, and oily after burning, it means that the mineral oil is excessive or borated.
3 water test emulsion
In the autumn and summer seasons, many people use lotions instead of creams, but the emulsion often contains a small amount of oil ester, which is easy to clog pores, causing dry and dehydrated skin, and the pores will gradually become larger over time.

On the other hand, if it is poured into the water, the emulsion sinks to the bottom, which proves that it contains no petroleum ester, so consumers can use it with peace of mind.
4 iodine distinguishes antioxidant function
Peeled apples will become yellow when exposed to the air, and iron will rust when exposed to the air for a long time. This is the result of oxidation by air. Our skin is exposed to the air and is also oxidized. Therefore, there is also a saying that anti-oxidation is anti-aging recently. At present, there are many products that emphasize the function of anti-oxidation. In the end, whether the product has such effect, a few drops of iodine can help test. First, pour some water into the transparent glassware, and add iodine in the water. The ratio of iodine to water is about 1:50. Shake well and put the products to be tested, such as toner and facial cleanser, a little. Stir well, if the product and liquid are fully dissolved and the water is clear and transparent, it has anti-oxidation function. If the water can not be reduced or blackened, it proves that the skin will continue to be oxidized by air. Will increase oxidation.
