5 benefits of using a lash serum

Overcome with lash concerns, but aren’t sure whether lash serums are worth the investment? Well, they’re used religiously for good reason, and we’re here to breakdown 5 reasons they’re a must-try if you’re working towards some personal lash goals, with many reviews swearing by positive before and after results…

1) Extra length

Longer lashes are the main reason many beauty lovers convert to a lash serum – and the secret’s in the formula. Ingredients like peptides help to encourage hair into the growth phase and keep them there longer than normal, in turn helping to promote length in shorter lashes. If you’re looking for the best eyelash serum for growth, we recommend Glow For It Lash Growth Serum, utilising peptide-powered action to support long, fluttery lashes with regular use.

2) Strengthening Properties

Lash serums also seek to minimise the risk of breakage, thanks to conditioning properties, moisture retention benefits and follicle nourishment. Packed with strengthening ingredients, lash serums help to fortify lashes from root to tip, anchoring hairs in place to promote a fuller, stronger appearance.

3) Deep moisture benefits

Brittle, breakage-prone lashes are often due to dehydration and dryness along the lash line. Lash serums can help to prevent this, often packed with nourishing and moisturising ingredients like hyaluronic acid, which seek to hydrate the hair shaft from the root and promote supple, conditioned lashes.

4) Minimised Risk of Shedding

Many lash serums are designed to increase the active growth phase of your natural lash cycle, thereby helping to reduce the risk of shedding. Ingredients like vitamins and amino acids applied to the follicle help to anchor the lash, fortifying the structural integrity to promote stronger results and a reduced chance of breakage.

5) Smoother mascara application

Everyone knows the secret to smooth mascara application is hydrated, healthy lashes. Lash serums support just that, coating every hair in a moisture-rich barrier that resists dryness and allows your favourite mascara to glide on effortlessly.
