Homemade cosmetics are slowly ruining your face

Ms. Li has recently been obsessed with making her own cosmetics. She firmly believes that only the skin care products she mixes by herself are safe and effective. But when she excitedly gave her homemade "pure plant face cream" to her best friend to use, her best friend had an allergic reaction. This can't help but make people think: Do we really understand the truth about cosmetics?

The essence of cosmetics: The combination of science and art

Cosmetics are not simple mixtures but scientific products calculated precisely. Take the most common moisturizing cream as an example:

• Aqueous phase ingredients: Accounting for 60 - 80% of the total weight, responsible for replenishing water
• Oil phase ingredients: Providing a water-locking barrier, accounting for 15 - 30%
• Active ingredients: Such as hyaluronic acid, vitamin E, etc., usually only accounting for 1 - 5%

Mr. Zhang, a formulator with ten years of experience, revealed: "A 30ml essence in the laboratory may need to undergo more than 200 stability tests."

Three major misunderstandings of DIY cosmetics

Many enthusiasts are prone to fall into the following traps:

• Natural ≠ Safe: The pH value of lemon juice can be as low as 2, and using it directly will damage the skin barrier
• Simple mixing ≠ Effective formula: Vitamin C will rapidly oxidize and become ineffective when it encounters metal ions
• Judging by the naked eye ≠ Sterile environment: The home environment cannot meet the microbiological control standards of GMP.

Data from Zhongshitong Laboratory shows that the rate of exceeding the standard for the total number of colonies in homemade cosmetics is as high as 73%.

Five guarantees of professional production

The value provided by regular cosmetic enterprises is often underestimated:

• Raw materials have undergone toxicological evaluations
• Formulas have undergone percutaneous absorption tests
• The production process complies with ISO standards
• Finished products have passed human patch tests
• The shelf life has been verified through accelerated aging.

"Consumers only see the final product and don't see the thousands of experimental data behind it." Mr. Zhang added.

Three-step rule for making wise choices

If you want to become beautiful safely, it is recommended that:

• Check the filing information (it can be checked on the website of the National Medical Products Administration)
• Choose a product line that suits your skin type
• Do a behind-the-ear test for new products first

Next time when you are attracted by labels such as "handmade" and "ancient method production", you might as well ask yourself first: Is beauty worth risking your health?
