Cosmetics contain different types of preservatives. Many merchants claim that their products are preservative-free, but that's impossible. Any product without preservatives cannot last long.
Why do products need to add preservatives?
Are preservatives, rapid weight loss anti-mildew agents, antibacterial agents, and sterilizing agents different?
Preservatives are commonly added in cosmetics. However, many sensitive-skinned women fear the sensitivity caused by preservatives and desire to find products without preservatives. If you also love cosmetics without preservatives? For healthy weight loss, then you need to master the key points of determining products without preservatives (Taizhou Makeup Training School [http://www.tz-ainisi.org]).
Their meanings in use are all the same. The difference lies in the dosage. When the dosage is low, it is called a preservative or bacteriostatic agent; when the dosage is high, it is called a sterilizing agent.
Reminder to readers: Regarding cosmetics, don't be too optimistic about believing [no preservatives added], and don't believe too much in those advertisements claiming no preservatives are used.
Why must preservatives be added?
The degree of harm preservatives cause to humans is related to the dosage. For the same preservative, if the dosage is too high, the skin will immediately show an allergic red spot reaction. If the concentration is appropriate, the skin may not immediately reject or have an allergic reaction, but there is still potential accumulative harm through absorption by the body (Taizhou Makeup School [http://www.tz-ainisi.org]).
Regardless of the manufacturing environment of cosmetics, to maintain a period of 3 years without microbial growth, adding a proper amount of preservatives is the safest approach for manufacturers. If consumers cannot accept moldy or bacteria-laden cosmetics, they must accept the fact that cosmetics contain preservatives.
Products that can undergo high-temperature sterilization after packaging generally have conditions to avoid adding preservatives. However, if you want fresh products without preservatives, the key lies in using them within the shortest possible time and refrigerating them if not finished. Cosmetics claimed to be preservative-free (Taizhou Makeup Training [http://www.tz-ainisi.org]) should at least meet 3-4 of the following criteria to be believable.
Are there really brands that do not use preservatives?
First, the capacity is extremely small.
Second, the indicated shelf life is short.
Third, the container is specially designed to minimize contamination from the environment or users.
Fourth, single-use products.
Fifth, dry powder products.
Sixth, highly moisturizing products with very high polyol content.
Seventh, products with very high alcohol content.
Eighth, essential oil products.
Ninth, pure oil-based products without water.
Tenth, manufacturing environments with high standards of dust-free and sterile conditions.
How to reduce the harm of preservatives?
Pursuing cosmetics without preservatives is impractical.
A bottle of cosmetics with many nutrients, opened and used for a long time without spoiling, generally contains excessive preservatives. Such products should not be used for face masks or instrument-assisted absorption, only suitable for normal daily use in the morning and evening.
For unfinished high-performance skincare products, if possible, store them in a refrigerator at 5-10°C, which not only slows down the growth of microorganisms but also preserves the nutritional value of active ingredients.
Face masks are intensive skincare products, using them once or twice a week is sufficient. Using them every day forces the entire face to soak in essence with high preservatives, which is not beneficial for the skin.
For intensive facial essences, if possible, choose single-dose packages with low preservatives. Apply them on clean skin as a base, then apply a pure moisturizing mask mainly composed of polyols. This not only significantly reduces the harm of preservatives but also improves the penetration effect of active ingredients.
Expert advice:
☆ Whether oil-soluble or water-soluble preservatives, their molecules are usually very small and easily absorbed into the skin.
☆ When skincare products are not acidic or sunscreens, if there is a noticeable stinging sensation upon application, it is usually due to excessive preservatives or the use of more irritating preservatives.
☆ The harm of preservatives is not just immediate allergic reactions but also potential accumulative damage.
☆ A good manufacturing environment is the only guarantee that preservatives are not excessively high. Choosing reputable products ensures the protection of your skin rights.
