Patch Testing: A Cornerstone Of The Beauty Industry

Countless cosmetics, moisturizers, hygiene products, and similar items are on the market these days. Some are made of all-natural ingredients, such as essential oils and botanicals. Others contain synthetic materials like parabens, chemicals, and artificial fragrances. Certain products fall somewhere in the middle of the spectrum with a combination of natural and synthetic components. While people have their own preferences in terms of which types of products they choose to use, all of them have certain benefits and disadvantages.

Whether a product is synthetic, natural, or a hybrid blend, it could potentially have an array of effects on the people who use it. It’s important that the companies developing those products understand the impact they may have on consumers. It’s also essential for consumers to know the possible effects of the products they use. This is particularly true when it comes to products that’ll be used on the skin, such as soaps, body washes, shampoos, conditioners, makeup, moisturizers, and anti-aging serums. That’s where beauty consumer testing comes into play.

Beauty and skincare products undergo numerous testing phases while they’re being developed and perfected. Some take place solely in the lab and revolve around how different ingredients interact with each other. For example, some ingredients can alter the aromas and effects of others. In the lab, product developers try various combinations to find out which ingredients react negatively with one another and which ones complement each other for heightened effects.

Of course, all products reach a point where lab experiments will no longer suffice. Still, they’re not quite ready to be sent to store shelves. Before being sold to the public, the products have to be tested on human skin. Otherwise, how will manufacturers and consumers know if they’re safe or if they might cause allergic reactions for some people? Patch testing bridges that gap.

Just like medications have to be put through human trials, cosmetics and other products that will come into contact with human skin must be tested on actual humans. Patch testing is the process of testing products on the skin to find out which types of reactions they may cause. Products or ingredients being considered for them are applied to adhesive patches and placed on the skin. Then, product developers monitor their test subjects to watch for any reactions to those patches.

You could compare it to testing cleaning solutions on a small, hidden patch of carpet to make sure they won’t damage it. Some carpeting might fade when exposed to certain cleaners. Others won’t. Along those same lines, people with sensitive skin or certain types of allergies could react badly to some skincare products or their ingredients. Others will have no reaction at all. If people show signs of negative reactions during patch testing, developers can then change the formulas of their cosmetics and skincare products accordingly.

From Development To Distribution

Skincare and beauty product manufacturers take care to use only products that have been deemed safe for the skin. They further test their products to make sure their ingredients work safely together. Still, testing can only go so far in the lab, and some side effects can’t be predicted. Human trials such as patch testing help fill in the blanks during the development phase so manufacturers can make sure their products are completely safe for people to use.
