In today’s beauty industry, words like non-toxic, clean, and natural are everywhere. But what do they really mean—and can you trust them? We’ve heard your questions, your concerns, and your curiosity. So Raynia from our content creation team sat down with our founder and CEO, Amy Ling Lin, to talk candidly about the truth behind the non-toxic label—and why she built sundays around creating a safer, more honest experience for all.

Let’s get into it!

A Conversation with Amy Ling Lin

Raynia: This is Amy, our founder, and she’s going to answer some of the questions you’ve been dying to know about the beauty industry.

Amy: Okay, let’s talk about this.

Raynia: First up—what does non-toxic actually mean when it comes to nail products?

Amy: Non-toxic means it’s safe for everyone. It’s safe for pregnant women, for children, for people with sensitivities. It doesn’t cause things like allergies or headaches. You know how sometimes you walk out of a nail salon and you feel a little dizzy or like you can finally breathe again? That’s the toxic fumes. A truly non-toxic product shouldn’t make you feel that way.

Raynia: A lot of people worry that non-toxic is just a marketing gimmick. What do you think?

Amy: Unfortunately, that’s true in many cases. You’ll see things labeled “10-free,” “14-free,” even “15-free.” While that’s a great starting point, it’s not the whole story. As consumers, it’s important to actually look at the ingredients—because some of those harmful toxins might still be in there under different names. That’s why at sundays, we do the research for you. Every single ingredient is carefully vetted for safety.

Raynia: What’s something you wish more people understood about non-toxic beauty?

Amy: I think a big misunderstanding is assuming that natural means non-toxic. That’s just not always true. Take eucalyptus—it’s a natural essential oil, but you can’t drink it. It can cause allergic reactions, and if you put it directly on your skin, it could even burn. Essential oils need to be diluted and used carefully. So just because something smells good or is labeled natural doesn’t mean it’s non-toxic. They’re totally different terms. You still have to check the ingredients and know what you’re putting on your body.

FAQ: Is Non-Toxic a Myth?

1. What does “10-free” actually mean?

It means the formula is free of 10 specific harmful chemicals commonly found in nail polish—like formaldehyde, toluene, and DBP. But numbers can be misleading. A product can be “10-free” and still contain other questionable ingredients.

2. Can something be natural but still toxic?

Yes. Many natural ingredients, like essential oils, can irritate the skin or cause allergic reactions if not used properly. Natural doesn’t always mean gentle or safe.

3. How do I know if a nail product is truly non-toxic?

Start by reading the ingredient list and looking for transparency from the brand. If you’re not sure what something is, research it—or choose a brand you trust to do that homework for you.

4. Is non-toxic safe for pregnant people and children?

It should be. At sundays, our non-toxic products are formulated with the highest safety standards, making them suitable for pregnant women, children, and anyone looking to avoid harsh chemicals.

5. Is fragrance always bad?

Not always—but it depends on what’s behind the fragrance label. Some fragrances are made from undisclosed synthetic chemicals, while others come from essential oils that can be irritating. Look for full transparency, and avoid vague terms like “fragrance” without explanation.
