Grandelash and Lashfridays are both lash growth serums acclaimed for their impressive effectiveness, backed by thousands of glowing reviews and testimonials. Still, it's important to note some significant contrasts between Grandelash and our lash serum.
We've composed an unbiased comparison of Grandelash and Lashfridays, outlining aspects like customer feedback, ingredients, pricing, and potential side effects, to provide you with a comprehensive overview for your consideration.
What Are Eyelash Serums
Eyelash serums are liquid formulas that enhance the natural growth cycles of lashes and make them appear thicker and longer. They stimulates the lashes in their growing phase and protects them from breakage while strengthening their roots. When applied daily, these lash serums make the eyelash appear fuller, stronger, and longer.
What Type of Lash Serum Are Grandelash and Lashfridays?
The main two types of lash serums are prostaglandin-based lash serums and peptide-based lash serums. Grandelash is a prostaglandin-based lash serum and Lashfridays is a peptide-based lash serum.
GRANDELASH: Prostaglandin
Prostaglandin-based lash serums contain hormones that can extend the duration of the growth phases of lashes. Similar to Rapidlash, Grandelash is a prostaglandin based lash serum containing Isopropyl Cloprostenate - a synthetic version of prostaglandin.
Prostaglandins are a group of naturally occurring lipids (fats) found in many parts of the body and are involved in a variety of biological processes.
Isopropyl Cloprostenate, specifically, is often used in eyelash growth serums due to its potential to stimulate the growth of eyelashes. It is believed to extend the growth phase of the eyelash hair cycle, leading to longer, thicker, and darker lashes.
Isopropyl Cloprostenate is structurally similar to the active ingredient (Bimatoprost) in a glaucoma medication called Lumigan, developed by Allergan. Doctors and patients noticed that Lumigan, when used to treat glaucoma, had a side effect of causing significant eyelash growth. This led Allergan to develop and market a new product called Latisse, using the same active ingredient but specifically for the purpose of promoting eyelash growth.
While Isopropyl Cloprostenate is a different compound than Bimatoprost, it's used in a similar way in some non-prescription eyelash growth products
How Does Isopropyl Cloprostenate work?
Now that we know what Isopropyl Cloprostenate is, let’s find how it works.
- Isopropyl Cloprostenate is believed to influence the growth cycle of eyelashes. More specifically, it seems to increase the duration of the Anagen phase (the growth phase) of the eyelash hair cycle, leading to longer lashes.
- This compound might also enhance the size of the dermal papilla – the part of the hair follicle where the hair actually grows. By doing so, it could potentially make the eyelashes thicker.
- Isopropyl Cloprostenate may stimulate the pigment cells (melanocytes) in the hair follicles, leading to darker lashes.
LASHFRIDAYS: Peptides
Peptides are chains of Amino acids. You might have heard about the importance of amino acids as these acids are the supporting and building bricks of protein chains in the human body. A peptide lacks the number of amino acids compared to protein, so increasing peptides in the body leads to better hair health.
Peptides also help in Collagen building. Collagen is basically a massive particle but helps the skin and hair to get better. But since the size of the molecule is so large, it cannot get into the skin if applied topically.
Peptides having the same constituents and being smaller in size can very well penetrate the skin and enhance the health of eyelashes. The other two proteins essential for hair and skin health are elastin and keratin, which have peptides. This is why peptides are so crucial for eyelash enhancement.
How Does The Peptide Compound Work?
The peptide serum provides the most significant peptide amino chain to the hair to strengthen it in its growth and after-growth phase.
- The basic peptide found in lashfridays is Myristoyl Pentapeptide-17. This compound is a highly performing constituent that hydrates the peptides and makes them appear healthier, thick, and shiny. It fortifies and rejuvenates the life of eyelashes, which intensifies the results.
- The peptide called Acetyl Tetrapeptide-3 aids in building stronger and fuller eyelashes and helps protect them from damage and breakage due to dryness. This peptide has proven to increase the strength of roots and thickness of lashes.
Other Ingredients
Aside from their main active ingredients, Grandelash and Lashfridays have the following key ingredients in their serums.
GRANDELASH
- Panthenol: Also known as pro-vitamin B5, it is often used in hair care products for its ability to coat the hair and seal its surface, lubricating follicles and making lashes appear shiny.
- Glycerin: This is a common humectant in skincare products, meaning it helps maintain moisture in the skin.
- Sodium Hyaluronate: This is the salt form of hyaluronic acid, a powerful humectant that can hold up to 1,000 times its weight in water. It is used for its ability to hydrate the skin and may help maintain the health of the lash line.
- Aloe Barbadensis Leaf Juice and Chamomilla Recutita (Metricaria) Flower Extract: Both ingredients are known for their soothing and anti-inflammatory properties, which can benefit the sensitive skin around the eyes.
- Various amino acids (e.g., Alanine, Arginine, Aspartic Acid, Glycine, etc.): These are the building blocks of protein and are vital to hair (lash) health.
- Tocopheryl Acetate: This is a form of Vitamin E, an antioxidant that can help protect the skin and hair from free radical damage.
- Magnesium Ascorbyl Phosphate: This is a stable form of vitamin C, another antioxidant that can help protect the skin and hair.
- Vitis Vinifera (Grape) Seed Extract: Rich in antioxidants, this extract may offer some protection to the hair and skin.
LASHFRIDAYS
- Purified water - Water is used as a solvent to dissolve the serum ingredients.
- Hyaluronic Acid - Hyaluronic Acid is also used to thicken the lash serum.
- Collagen - Collagen enhances the appearance and feel of lashes by increasing lash body, suppleness and sheen.
- Cucurbita Pepo Pumpkin Seed Extract - The oil from pumpkin seeds helps increase hair growth.
- Sphingolipids - Sphingolipids are complex, long chain lipids (fats) that function as conditioning ingredients.
- Arginine - Amino acids that help condition lash hair.
- Biotin (Vitamin B7) - Biotin adds body and shine to lash hair.
- Keratin - Keratin is a type of protein that works by smoothing down the cells that overlap to form your lash hairs. This can make them smoother.
