Keratin eyelash curling has been a hot topic in the eyelash circle in recent years. The feature of "natural curling without eyelash extensions" has attracted many people to try it. However, the reviews on the Internet are different. Some people highly recommend it, while others say that the effect is different, and even dry or thinning eyelashes occur. This article does not give a conclusion, but just wants to take you to clarify the true appearance of this technology: from the principle, reaction differences to the current legal status, to help you make your own choice firmly.

💡 A quick summary of the key points of this article:

  • Technical positioning and application method of keratin eyelash curling
  • Differences in side effects and reactions
  • Who might be more likely to react poorly?
  • Legality still unclear


What is keratin eyelash curling? The focus of discussion changes from usage trends



Keratin eyelash curling has been gradually noticed in eyelash beauty services in recent years. Its main point is simple: without eyelash extensions or eyelash curling every day, the original eyelashes can be naturally curled up and look more energetic. This technology is usually used with some soft or moisturizing liquid to treat the eyelashes. It is gentle and non-irritating. Some people regard it as a more relaxed way to groom eyelashes.

But the feedback from people who have actually done it varies. Some say the effect is good and that they can put on makeup faster in the morning; others feel that there is not much difference, and even mention that their eyelashes become drier or brittle after the procedure. These differences may be related to the condition of individual eyelashes, the combination of products used, and even the operation method.

This service is not without controversy in Taiwan. Sometimes you hear discussions about its legality, but there is no unified definition in the regulations, and everyone has a different understanding of the matter.


How is it different from traditional eyelash curling? Clarify the technical positioning from the ingredients and operation methods



At first glance, keratin eyelash curling and traditional eyelash perming are quite similar, both of which are ways to make eyelashes curl. However, a closer look reveals that the two are actually somewhat different in terms of purpose and ingredients used. Traditional eyelash curling is more like perming hair, which aims to achieve a clear curl and emphasizes a clear effect and long-lasting effect. Keratin eyelash curling, on the other hand, focuses on following the growth direction of eyelashes, making the eye shape look naturally enlarged and not too curved.

There are also differences in the liquid used. Keratin eyelash curling often claims to have added keratin, moisturizing factors and other ingredients. Some operators also use the terms "nourishing eyelashes" and "repairing and reducing damage" to introduce this technology. Overall, it is more like an eyelash beauty service between maintenance and styling.

However, no matter which method is used, the actual effect is still related to the condition of the eyelashes, the technique of the artist, and the product combination. This is why some people think that there is not much difference, while others think that the feeling after the two are completely different.


Who may not respond well to keratin eyelash curling? Combining physical conditions and online observations

Keratin eyelash lift is indeed a relatively non-invasive technology, but from the feedback on the Internet, some people's experience after the application is not as smooth as expected. These differences are mostly due to personal skin quality, eyelash condition, or the conditions set at the time of application.



The more commonly mentioned situations include:

  • People with thin, dry, and brittle eyelashes are more likely to feel the hair becoming brittle after the operation.
  • People with sensitive skin around eyes may feel itchy or temporarily red during the procedure.
  • People with chronic allergies or oily eye area : The overall experience may be affected due to unstable cleansing or makeup retention.
  • People who have had sensitive experiences with eyelash products may also react slightly more strongly to eyelash curling liquids.
  • Those who have experienced discomfort from eyelash perming are generally more cautious about similar styling treatments.


In addition to these physical differences, some people will also pay attention to these details before the operation:

  • People who have just had eyelash extensions often choose to wait until the false eyelashes fall off naturally before taking any further action.
  • When there is obvious instability around the eyes (such as stye, eczema, unhealed wounds, etc.), it is rarely performed in this situation.
  • The mascara is not completely removed on the day of application : Some people have found that this will affect the effectiveness of the eyelash curling liquid.


These experiences are not used to draw a line that cannot be crossed, but to give people more reference points when considering their actions. Sometimes, understanding your own situation is more important than getting advice.


The current legal status of keratin eyelash curling: pharmaceutical standards and regulatory gaps still need to be clarified

Currently in Taiwan, the products used for keratin eyelash curling have not yet been clearly approved by domestic regulations. This means that the circulation and use of these products in Taiwan may involve regulatory considerations. Although there are various products on the market that claim to have special formulas, it is recommended that when considering such services, you can learn more about the current situation and potential risks, and make the most suitable choice for yourself.

Whether or not you care about this depends on different considerations. Some people will choose to ask for product information, while others will observe whether the operating environment or process makes them feel at ease. These methods are not standard answers, but a common process of exploration when facing new technologies.

When the regulations are not yet complete and information is still changing, instead of pursuing "how it must be done", it is better to first understand "how this thing looks like now", which may bring you closer to the choice you want.


Behind every choice, it is worth having complete information to help you clarify



Keratin eyelash curling is not a single-choice question of good or bad, but a personal choice based on "whether it is suitable for your current state". When there are various different experiences and reviews on the Internet, calmly understanding the principles, risks and current conditions is the starting point for making a safe choice. If you really want to try it, don't forget to choose an eyelash salon with sufficient experience, professional operation, and willingness to communicate, so that every treatment you have can be safe and stable, and become a small happiness in your daily life.
