Are Lash Growth Serums Safe?

Lash Growth Serum

Lash growth serums are a growth-enhancing formula that triggers the length and thickness of the eyelashes. They stimulate lash growth, and when applied regularly, the serum extends the telogen growth phase and lengthens the lash growth cycle. On the other hand, the Food and Drug Administration (FDA) has approved many lash growth serums safe for use but with a stern warning.

The only approved lash growth serum is Latisse, which requires a prescription. Although most lash growth serums are FDA-approved, they can still cause allergic reactions such as itchy red eyes, darkening of the eyelid skin, and increased pigmentation of the iris. Therefore, many women have opted out for a DIY lash growth serum to avoid the allergic reaction above.

In summary, whether lash growth serums are safe depends on the person because, just like any other skin product, lash growth serums could have certain ingredients that can cause allergic reactions in some people.

Some people may react to the ingredients while some may not, and the symptoms include itchiness, inflammation, and redness around the eyes. Nonetheless, DIY lash growth serum doesn’t only encourage your lashes to grow; it also gives a natural look and saves time and money.

How Do Lash Growth Serums Work?

Lash growth serums work by hydrating and strengthening the lashes to grow fuller and healthier. The common ingredients found in most lash growth serums are;

1. Amino acids

Its principal function is to build hair follicles, help maintain the lashes’ strength, and promote overall lash health. Amino acids work well with peptides.

2. Ceramides

Fat molecules (lipids) help the lashes retain and lock in moisture.

3. Panthenol

To hydrate and protect the lashes from breakage. It is also known for its moisturizing, soothing, and repairing properties.

4. Peptides

To nourish and strengthen the lashes, repair damage to the hair, and improve the appearance of the lashes.

5. Biotin

To improve the hair’s health and strengthen the keratin in lash hairs. When you apply biotin to your lashes, they will be stronger and prone to breaking.

6. Plant Stem Cells

Plant stem cells reside at the base of the hair follicles and play an essential role in lash growth. The stem cells also can transform into different kinds of cells.

For instance, during the anagen phase of hair growth, the stem cells develop into cells called keratinocytes. They help the lashes grow by reducing the harm caused by UV radiation.

Despite having all these ingredients, it is essential to note that not all lash serums are created equal, and for this reason, most of them work by conditioning the lashes but may not contribute to the growth of the lashes. On this note, if you are looking for a lash serum that contributes to the substantial growth of the lashes, look out for the ones with ingredients like bimatoprost, isopropyl cloprostenol, or prostaglandin analog.
