Eyelash Serums Explained: What They Can and Cannot Do

What is an eyelash growth serum, and does it work? "Eyelash growth serum" is a popular name for lash serums, which are applied along the lash line. Cosmetic serums are designed to condition lashes so they look fuller and feel softer, while products that truly change lash growth are prescription drugs. Here is what to know before you buy.

What Are Eyelash Serums?

Long, fluttery lashes are popular, and many people look for alternatives to monthly lash extensions. Lash serums are one of those options. They are liquids applied with a thin brush along the base of the upper lashes, usually once a day.

It helps to be realistic about what they do. A cosmetic lash serum is a conditioning product. It can help lashes look and feel more nourished, and some people find their lashes look fuller over time with consistent use. It is not a substitute for extensions, and results vary from person to person.

Eyelash Conditioner vs. Eyelash Serum

The two terms are often used interchangeably, but they are not always the same thing. An eyelash conditioner typically contains emollient and humectant ingredients that coat the lash hairs, helping them feel softer and look smoother. A lash serum is usually a lightweight liquid with conditioning ingredients that is applied along the lash line.

What Is in an Eyelash Serum?

Cosmetic lash serums usually combine conditioning and moisturizing ingredients. Some common types include:

• Biotin: a B vitamin often included in beauty products for conditioning.
• Panthenol: a form of vitamin B5 that helps moisturize and condition hair.
• Peptides: short chains of amino acids commonly used in conditioning formulas.
• Hyaluronic acid: a hydrating ingredient that can help lashes feel moisturized.

Cosmetic brands market these ingredients as conditioning, but a cosmetic cannot be sold as a way to change how lashes grow. Prescription lash treatments are different. They contain prostaglandin analog medicines, which are regulated as drugs and are used under a doctor's care. They can cause side effects such as eye redness, itching and darkening of the eyelid skin. The FDA has also warned about products sold as cosmetics that contained undisclosed drug ingredients, so it pays to read labels and buy from sellers you trust. If you are interested in a prescription option, talk to your doctor or eye care professional.

How to Apply Eyelash Serum

Applying eyelash serum is simple. Here is a step-by-step guide, but always follow the directions on your specific product:

1. Start with clean, makeup-free lashes. Use a gentle cleanser or makeup remover to take off makeup and debris.
2. Remove excess serum from the applicator. Wipe the brush on the edge of the container or a tissue.
3. Apply along the base of your upper lashes. Use a small amount along the lash line, and keep it out of your eyes.
4. Let it dry. Allow the serum to dry completely before applying other eye products or going to bed. This usually takes a few minutes.
5. Use as directed. Most lash serums are used once a day, often in the evening.

Do a patch test first: apply a small amount of any new product to the inside of your wrist or behind your ear and wait 24 hours. Stop use and see a doctor if you notice redness, swelling, itching or irritation around the eyes. Do not use any eye product if you have an eye infection or irritation.

Eyelash Care and Maintenance

Lashes are delicate. A few everyday habits can help them look their best:

1. Be gentle when removing makeup. Harsh rubbing or pulling can cause lashes to break. Use a gentle makeup remover and a soft cotton pad.
2. Do not wear waterproof mascara every day. It can be hard to remove, and rubbing to remove it can be rough on lashes.
3. Consider a conditioning lash serum. A lash serum can help lashes feel moisturized and look fuller.
4. Go easy on eyelash curlers. If you use one, be gentle and avoid tugging.
5. Keep lashes moisturized. A conditioning product can help lashes feel softer.
6. Avoid rubbing your eyes. Rubbing can irritate the delicate skin around your eyes and pull on lashes. Use a clean tissue to gently dab instead.

Conclusion

Lash serums are conditioning products that can help lashes look fuller and feel softer with consistent use, but they are not a quick fix and results vary. They are not the same as prescription lash treatments, which are medicines. Apply carefully, patch test, take good care of your lashes and talk to a doctor with any concerns.
