Clinical Trials vs. Consumer Perception Studies in Skincare
Traditionally, skincare clinical trials involve collecting quantifiable data about a product's performance on certain endpoints. For instance, an interventional model may be used to test how well a serum reduces the occurence of breakouts when used daily for eight weeks. Professional skin analysis may occur in addition to participants reporting breakouts. Consumer perception studies instead focus on participants' self reported experiences of a product. In the breakout-fighting serum example, participants in a consumer perception study might also use the product for eight weeks and provide feedback via. validated questionnaires.
Benefits of Clinical Research for Common Heir and Other Brands
Without clinical evidence, it can be difficult for consumers to trust that product claims accurately present a formula's benefits. In the case of Common Heir, it is espescially vital for skincare products to have clinical backing, as claims within the industry can often be vague or overstated. Clinical support enables skincare brands to maintain regulatory approval and consumer loyalty.
In a six-week study with subjects aged 18-55, 82% of the participants saw an improvement in hyperpigmentation and 96% said they’d recommend it to a friend.
