You must have seen us mention that our nail polishes are “21-Free”. But what does it even mean? Let’s take a deep dive into it.
At Miss Nails, we believe beauty should feel as good as it looks, and we believe in complete transparency. We believe that you should know what you are putting in/on your body.
What Does 21-Free Nail Polish Really Mean? (And Why It Matters)
Let’s break it down in the simplest way possible.
“21-Free” means the nail polish formula is created without 21 potentially harmful chemicals that are commonly found in traditional nail polishes.
These chemicals have been associated with concerns like irritation, allergies, endocrine disruption, or long-term health risks . And that is why cleaner formulations are becoming the standard in the nail industry.
In short:
✨ Same gorgeous color payoff
✨ Same glossy, salon-quality finish
✨ But without the unnecessary harsh additives

Why Does 21-Free Nail Polish Matter?
1. Better for Sensitive Nails & Skin
If your nails feel weak, peel easily, or react to polish - a cleaner formula can make a visible difference.
2. Reduced Exposure to Harsh Chemicals
Many excluded ingredients are known irritants or suspected endocrine disruptors, which is why conscious beauty brands are phasing them out.
3. Safer for Regular Use
If you paint your nails often (hello weekly mani lovers 👀), using a cleaner formula helps minimize repeated chemical exposure over time.
4. Conscious Beauty Choice
21-free is not just about nails - it reflects a larger shift toward mindful, ingredient-aware beauty.
Does “21-Free” Mean the Polish Is Completely Chemical-Free?
NO - and that’s important to understand.
Nail polish will always need certain functional ingredients to give you:
-
Smooth application
-
Strong adhesion
-
Long-lasting wear
-
High shine finish
21-free simply means removing unnecessary or higher-risk ingredients while keeping performance intact. And yes, you still get that glossy, salon-like finish you love 💅
