Ingredient
How should I read polyhydroxy-acid labels on a label?
PHA is a broad cosmetic category label; gluconolactone is one ingredient discussed in this area. A category’s reputation for gentleness is not a tolerance guarantee.
Gentle is a reputation, not a promise
Use the exact ingredient and finished formula as your starting point. A safety literature review is not evidence that every product or concentration is right for an individual. Our profile can keep an exfoliating category optional without recommending it for a reactive-feeling answer.
Try this
- Read the exact ingredient rather than only PHA.
- Check concentration when the brand actually provides it.
- Keep personal tolerance uncertain until appropriately assessed.
