Our Product Rating System
First, Camille (co-creator of Welpr) hand picks cleaner product options from a variety of sources.
Next, we collect information about each product's safety, consumer satisfaction, and eco-ethical standing.
Finally, we run all this information through an algorithm that calculates the Welpr Rating.
Welpr Rating:
5.0/5
Part 1: Product safety
We evaluate safety information from 3rd party organizations (e.g. EWG, Made Safe, etc.). Instead of relying solely on any one of these companies for safety information, we assess all of them.
Part 2: Consumer satisfaction
We scour the web for consumer ratings and reviews to verify products are not only cleaner options, but also effective. Products can either be Above Average, Average, or Below average for their respective category (e.g. cleaning products).
Part 3: Ethics & Environment
When you buy a product, you’re supporting that company with your dollars. We believe it’s important to support ethical companies, so we pool together certifications that verify a company's ethics and environmental impact.
Common Harmful Chemicals in Vitamin C Serum
Chemical Name
Why it’s harmful
Retinol
Oral administration of high doses in adults causes ciricrhosis, hemorrhage, anorexia, jaundice, and dermatitis. The use of this substance is contraindicated in pregnancy at doses larger than the FDA recommend daily allowance. Ingesting 25,000 IU/d over a period of 2-3 weeks may result in toxicity, symptoms of which include liver injury and increased intracranial pressure, leading to blurred vision, headaches, and changes to mental status. The substance is also found to be an irritant and harmful if ingested, with teratogenic effects observed in experimental animals.
Butylated Hydroxyanisole
3-tert-Butyl-4-hydroxyanisole is a component of the food preservative Butylated Hydroxyanisole, used where Butylated hydroxytoluene is restricted. It serves as an oxidation inhibitor for human consumption. Despite lacking human studies, animal tests reveal no mutagenic activity. Its mutagenicity was evaluated using Salmonella typhimurium and Chinese hamster fibroblast cell line, with chromosomal aberrations induced only in the presence of the S9 mix.
Benzoyl Peroxide
Benzoyl peroxide is a versatile compound used in various industries, including pharmaceutical and cosmetic industries, mainly to treat mild acne and acne rosacea. In humans, occasional symptoms of overexposure include skin, eye, and mucous membrane irritation, and dermatitis. It has also shown potential for inducing DNA damage in cultured human cells. In animal studies, benzoyl peroxide has caused irritation, erythema, and increased keratinocytes in guinea pigs and mice. Studies on mice and rats showed no significant increase in tumors, and it was not found to be mutagenic in a Salmonella strain. In embryonic studies, however, it caused malformations at moderate frequency. Furthermore, it mediates its effect by inducing various genetic and biochemical changes in different cell types.
