What is citric acid?
Citric acid is a natural acid found in citrus fruits. It's known as alpha-hydroxy acid, and is often used in anti-aging skincare to promote skin peeling and regrowth.
What is it used for?
Citric acid is used as:
- a chelating agent (improves stability upon contact with air - stops the product going off)
- a pH adjuster (ensures that the product is not too acidic and not too alkaline, in other words, that it is mild and non irritating).
Is citric acid safe?
