Cosmetics are meant for beautification and can delay the aging process. However, low-quality products can damage your appearance. Testing your cosmetics reveals their reliability.Place a small amount of cream in a spoon and heat it over an alcohol lamp or candle. A standard-compliant product will behave like milk when boiled—its scent remains unchanged and becomes richer. If it spatters, emits thick smoke, develops a pungent odor, or leaves oily residue in the spoon after burning, it indicates excessive mineral oil or boron-based fillers.
Lotion:
Pour an appropriate amount of lotion into water. If it floats on the surface, it contains petrolatum. Petrolatum damages skin, causing dryness and dehydration as it clogs pores. Over time, pores become increasingly enlarged.Gently shake the mixture. If the liquid turns milky white, it contains emulsifiers—surfactants that disrupt skin tissue structure, causing sensitivity and exhibiting strong carcinogenic potential. Conversely, if the lotion sinks to the bottom when added to water, it is free of petrolatum and safe for consumer use.For cream-based products: Place a small amount on a regular spoon and heat it over a flame until completely burned. If black residue remains, it indicates various additives—the more residue, the higher the additive content. Next, place a cotton swab in the spoon, ignite it, and observe if the liquid emits black smoke. Avoid using such products.
Toner:
1. Shake vigorously and observe the bubbles afterward.
a. Few bubbles indicate low nutrient content.
b. Many large bubbles suggest salicylic acid. While effective for cleansing, it's highly irritating and prone to causing allergies.
c. Numerous fine bubbles that dissipate quickly indicate alcohol content.
d. Fine, abundant bubbles forming a thick layer that persists indicate a high-quality toner.
2. Quality toners lack an alcohol scent. Inferior ones may feel cooling upon application and carry a noticeable alcohol odor.
3. Most toners have color. Improper storage—such as prolonged sun exposure or extended shelf life—can cause color fading.
Creams:
1. Many moisturizing products contain mineral oil. Apply a small amount to paper, let it sit, then wipe off the excess. If it's a moisturizer, the paper will wrinkle. If it contains mineral oil, the paper will remain transparent!
2. Alternatively, place a small amount of the product on a metal spoon and heat it over a flame. If mineral oil is present, it will melt and separate from the product!
3. When creams are properly packaged with fine texture, their surface appears uniformly smooth without visible pores.
Serums:
Drip serum onto a stack of tissue or cotton pad to observe penetration. The easier it seeps downward, the smaller its molecules and stronger its penetration—indicating better skin absorption.If it merely spreads across the surface, it indicates poor penetration and absorption.
Skincare Products: Apply a small amount to the back of your hand. After 3-5 minutes, gently press with an oil-absorbing sheet. If significant oil is absorbed, it indicates poor absorption and excessive oiliness. Conversely, minimal oil absorption suggests the product is easily absorbed and lighter in texture.
Alternatively, apply a small amount to the back of your hand. After 3-5 minutes, rotate your hand under light. If a greasy sheen remains visible, the product is too oily and poorly absorbed.
Makeup Remover Oil:
Add a few drops of makeup remover oil to a cup of water. Stir until the oil and water fully emulsify into a white mixture. If transparent oil droplets remain floating on the surface, these oils cannot be emulsified and washed away. If these oils contain acne-causing ingredients, it's advisable to wash your face again after using the makeup remover oil.
Lipstick:
Draw a lip shape on a blotting paper with a pencil. Apply the lipstick you wish to test completely within the drawn lip line. Leave it overnight. The next day, examine the lipstick on the blotting paper. The wider the area where oil seeps beyond the penciled lip line, the higher the oil content of the lipstick and the better its moisturizing properties.
Exfoliating Products:
Our skin consists of the epidermis, dermis, and subcutaneous tissue. The epidermis itself has five layers: the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale.New cells formed in the basal layer remain there for 14 days before reaching the stratum corneum. After another 14 days in the stratum corneum (epidermal layer), they die and shed. With normal bodily functions and metabolism, the typical cell renewal cycle is 28 days. However, aging, environmental pollution, and poor-quality cosmetics can disrupt this process. Accumulated dead skin cells easily clog pores, making regular weekly exfoliation essential.
Exfoliating products are excellent for weekly care, but many contain glass-like silica particles. These sharp materials can scratch the skin, so manufacturers often add mineral oil for lubrication. Mineral oil is a low-cost, highly stable byproduct refined from petroleum.Due to their larger particles, these can clog pores. Long-term use may damage skin and even scrape away healthy cells undergoing metabolism. Testing method: Apply a small amount to the back of your hand and gently rub. Observe if the area becomes oily or if large particles are visible. If so, avoid using the product.
Foundation:
Place an appropriate amount into water and observe its reaction. Typically, one of three scenarios occurs: it sticks to the cup's rim, floats on the water's surface, or sinks to the bottom. These three outcomes reveal the ingredients it contains:
1. Sticking to the rim indicates animal oil. This is extracted from animals.Consider this: Which cosmetics factory operates adjacent to an animal slaughterhouse? None. Slaughterhouses kill animals, then pile bones and hides aside until a large quantity accumulates. Only then are these materials transported to cosmetics factories. Who knows how long they've been stored? In summer, might these materials spoil or rot?Consuming spoiled food causes vomiting and diarrhea. Skin reacts similarly—using cosmetics made with spoiled ingredients triggers allergies. Manufacturers know this, so they add soothing agents and desensitizers during production. Soothing agents are anesthetics that numb the immune system. They feel great initially, but lose effectiveness over time. Beauty professionals know that after 2-3 years of using the same brand, you should switch. What are you switching to?They switch the soothing agents.Light oil provides excellent moisture retention but lacks breathability—like wearing leather pants in winter. Your legs feel damp and suffocated. This impairs skin permeability, accelerating aging. 3. The sediment at the bottom contains heavy metals like lead and mercury.If your product doesn't stick to the cup's rim or float, congratulations—you've chosen a quality product. You can use it with confidence. Try this test at home! Ladies, don't blindly follow trends and end up using the wrong products. That's not worth the cost. After all, health matters far more than beauty.
