What is the Vitamin C skincare product?
The Vitamin C formulation uses a 10% concentrated form that is stable, effective, and goes deeper to absorb better. Their biodegradable, single-dose capsules ensure a lifespan up to 18 months.
How was the Vitamin C serum tested?
The Vitamin C serum drops were tested on participants aged 18-55 over the course of eight weeks. Data about participants' experience was collected throughout.
Does Skincare Require Clinical Evidence?
Despite common misconceptions, skincare products are required to have some form of research backing behind their product claims. This is regulated by the FDA and the FTC, both of which require the validation of skincare marketing through clinical trials or other research methods.
Benefits of Clinical Research for Common Heir and Other Brands
Obtaining clinical support for skincare product claims is key to staying competitive in the ever-crowded market. It's essential to evidence your formula's efficacy with real data, as Common Heir did, to market your skincare products with confidence.
