Calcium Hydroxyapatite, also known as Durapatite in the United States Adopted Name (USAN) system, is a naturally occurring mineral form of calcium apatite. It is primarily composed of calcium and phosphate, with the chemical formula Ca10(PO4)6(OH)2. This compound is a major component of bone and teeth, giving them their rigidity and strength.
Historically, Calcium Hydroxyapatite has been extensively studied for its role in bone health and regeneration. Its biocompatibility and osteoconductive properties made it a popular choice in medical applications such as bone grafts and dental implants. Over time, researchers discovered its potential benefits for skin conditioning, leading to its incorporation into cosmetic products.
The process of creating Calcium Hydroxyapatite for cosmetic use involves synthesizing it in a controlled laboratory environment to ensure purity and consistency. Typically, this involves a chemical reaction between calcium and phosphate sources under specific conditions to form the hydroxyapatite crystals. These crystals are then finely milled to create a smooth, uniform powder that can be easily incorporated into various skincare formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Calcium Hydroxyapatite:
Calcium Hydroxyapatite is primarily known for its skin conditioning properties. This means it helps to maintain the skin in good condition by improving its texture and appearance. When used in cosmetic formulations, it can help to make the skin feel smoother and more supple. This is particularly beneficial for those looking to enhance the overall feel and look of their skin, making it a popular choice in skincare products.
Note: The listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Calcium Hydroxyapatite is generally considered safe for topical use in cosmetics. However, as with any ingredient, there are potential side effects that users should be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Calcium Hydroxyapatite during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.
Side effects and adverse reactions from Calcium Hydroxyapatite are relatively uncommon. However, it is always a good practice to conduct a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Calcium Hydroxyapatite has a comedogenicity rating of 1, which means it is very unlikely to clog pores. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts.
