When “HEMA-Free” Still Isn’t the Whole Story

Gentle formulas matter — but understanding matters more.

温和配方很重要，但理解更重要。

At NFormula Life, we believe transparency is part of care.

As awareness around nail product sensitivity grows, many people look for formulas labeled HEMA-free, TPO-free, or TMPTA-free — and rightly so. These ingredients are known to carry a higher risk of irritation for some users.

However, removing a few high-risk ingredients does not automatically mean a product is completely allergy-proof.

Because sensitivity is never about just one ingredient.

在 NFormula Life，我们始终相信——真正的温柔，来自透明与理解。

随着大家对美甲过敏问题的关注提升，
「不含 HEMA / 不含 TPO / 不含 TMPTA」
已成为许多人选择产品的重要条件，这确实是非常正确的方向。

但需要理解的是：
去除高风险成分，并不等于绝对不会过敏。

因为，过敏从来不是只针对某一个名字。

1. Sensitivity Is Personal

过敏，本质上是个体差异

Allergic reactions vary from person to person.

Some individuals may react to acrylates, photoinitiators, or even stabilizers that are otherwise considered gentle. Others may develop sensitivity over time through repeated exposure — even if they used similar products for years without issue.

This is known as cumulative contact sensitivity.

每个人的皮肤与免疫反应都不同。

有些人可能对其他丙烯酸酯类、光引发剂或辅助成分产生反应；
也有些人是在长期反复接触后，才逐渐出现不适。

这种情况被称为：累积型接触性过敏。

2. Curing Matters More Than You Think

是否“完全固化”，比成分更关键

Incomplete curing is one of the most common causes of irritation.

Thick application, darker pigments, magnetic particles, or insufficient lamp power may leave active monomers beneath the surface — increasing the risk of skin sensitivity.

Proper curing is essential for comfort and safety.

未完全固化，是最常见却最容易被忽略的过敏原因之一。

• 上胶过厚

• 猫眼、色粉较多的颜色、磁粉

• 灯功率不足或老化

都会导致底层胶体未完全固化，
而未固化的活性单体，正是刺激皮肤的主要来源。

3. Skin Contact Changes Everything

是否接触皮肤，决定风险高低

Even gentle formulas are designed for nail plates — not skin.

Repeated contact with cuticles or surrounding skin increases the likelihood of irritation, especially if the skin barrier is compromised.

Avoiding skin contact is always recommended.

即使是温和配方，也只适用于甲面，而非皮肤。

当胶体反复接触甘皮、侧缘，
或在皮肤受损的情况下操作，
过敏风险都会明显上升。

因此，避免接触皮肤始终是最重要的原则之一。

4. What “Gentle” Really Means

温和，不等于零风险

At NFormula Life, our formulas follow EU cosmetic standards and are carefully designed to reduce known irritants.

But honesty matters:
No professional nail product can be guaranteed 100% allergy-free for every individual.

Gentle formulas reduce risk — they do not eliminate individuality.

在 NFormula Life，我们严格遵循欧盟化妆品规范，
并尽可能降低已知致敏风险。

但我们也选择诚实地说清楚：
没有任何专业美甲产品，可以对所有人做到 100% 不过敏。

温和，是降低风险；
不是否定个体差异。

Our Gentle Reminder

温柔使用建议

• Avoid skin contact

• Cure thoroughly with appropriate lamps

• Perform a patch test if you have sensitive skin

• 避免产品接触皮肤与甘皮区域

• 使用合适功率的灯具，确保充分、完整固化

• 若属于敏感肌肤，建议在首次使用前进行局部测试

Closing Thoughts

最后总结

True care is not about promising perfection.
It’s about respecting the body, understanding limits, and choosing better — gently, over time.

真正的呵护，不是承诺“绝对不会”，
而是尊重身体、理解差异，
在温柔中，做出更好的选择。
