Skin tone scale, product details, positive and negative ingredients or materials are all different topics. Here is a summary of each topic:
Skin Tone Scale
- The Fitzpatrick skin types (FST) or phototypes refer to a skin tone scale developed to classify skin coloring and response to UV radiation.
- The scale ranges from I to VI, with I being the lightest and VI being the darkest.
- The scale is used by medical professionals to assess risk for sunburn and skin cancer, and to determine the setting on a laser when performing laser hair removal.
- The scale has some limitations, such as its focus on the words "tan" and "burn," which can mean different things to different people.
Product Details
- Ingredients like stabilized L-ascorbic acid, arbutin, kojic acid, azelaic acid, mulberry extract, and tranexamic acid are some of the favorite ingredients to incorporate into a daily home care regimen before any treatment performed on darker-skinned clients.
- For light-skinned clients, topical hydrators, emollients, antioxidants, and UV protection ingredients like stabilized vitamin C, vitamin E, and many B vitamins are recommended.
- The Think Dirty® Product Rating Scale is defined in the table below, and evaluations are performed by a Chemistry Team and Advisory Board with extensive experience in relevant fields such as Medicine, Biochemistry, Biology, Physiology, Environmental Toxicology, Environmental Health & Safety, and Chemical Engineering.
Positive and Negative Ingredients or Materials
- The Think Dirty® Product Rating Scale rates products based on the toxicity of their ingredients, with a rating of 10 assigned to products with several high-rated ingredients.
- The EWG Skin Deep® Cosmetics Database evaluates ingredients based on information culled from ingredient labels and from the scientific and industry literature on personal care products.
- The use of ingredients that stimulate the skin, such as alpha-hydroxy acids, should be used with caution on darker-skinned individuals.
- The MST Scale is an important next step in a collective effort to improve skin tone inclusivity in technology.
In summary, the Fitzpatrick skin types are a skin tone scale used to classify skin coloring and response to UV radiation. Ingredients like stabilized L-ascorbic acid, arbutin, kojic acid, azelaic acid, mulberry extract, and tranexamic acid are recommended for darker-skinned clients, while topical hydrators, emollients, antioxidants, and UV protection ingredients like stabilized vitamin C, vitamin E, and many B vitamins are recommended for light-skinned clients. The Think Dirty® Product Rating Scale and the EWG Skin Deep® Cosmetics Database evaluate ingredients based on their toxicity. Finally, the MST Scale is an important next step in a collective effort to improve skin tone inclusivity in technology.
