However, OPI nail polish does contain formaldehyde, which is a common ingredient in nail polish. It acts as a hardener, helping the polish to dry quickly and resist chipping.
While formaldehyde is a known irritant and can cause allergic reactions in some people, it is present in very small amounts in nail polish.
If you have concerns about formaldehyde in your nail polish, you can look for brands that are formaldehyde-free or choose to use a natural nail polish.
It's always a good idea to check the ingredient list of any nail polish you buy, especially if you have sensitive skin or are prone to allergies.
