The Pandemic Probably Caused Your Brows to Thin

It's no secret that the stress of the COVID pandemic has taken its toll on our collective psyche and follicles. A researcher International Journal of Dermatology and. The US National Library of Medicine (NCBI) estimated that nearly 25% of patients with long-term COVID symptoms reported experiencing hair loss. Premature thinning can also be brought on by deficiencies in biotin and iron. The reality is that thinning hair on the brows and scalp affects all of us- it's just a matter of when. It's no wonder why more people are turning to lash and brow thickening serums (Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7665672/)

How Peptides Help Promote Visibly Thicker, Fuller Brows

Peptide-based lash and brow serums and prostaglandin-based lash and brow serums are widely available for purchase at Ulta, Sephora, and Amazon. The latter includes ingredients such as:

  • Ethyl Tafluprostamide CAS 1185851-52-8 (also known as Dechloro Dihydroxy Difluoro Ethylcloprostenolamide or DDDE) and
  • Isopropyl cloprostenate CAS 157283-66-4.

These ingredients are in the same class of drugs such as bimatoprost traditionally prescribed by ophthalmolgists for the management of glaucoma symptoms. Unwanted side effects range from hyperemia to deepening of the upper lid sulcus, which has led regulatory bodies in the EU, Canada, and New Zealand to either restrict or ban their use in cosmetics outright (in the US, isopropyl cloprostenate is on the FDA's 2023 Priority List). These side effects are often downplayed by beauty companies, leaving many consumers unaware of potential risks.

Peptide-based serums, on the other hand, rely on a combination of polypeptides, fatty acids, and an emollient-based delivery system. Peptides include:

  • Myristoyl pentapeptide-17
  • Biotin tripeptide-1
  • Acetyl tetrapeptide-3
  • Acetyl hexapeptide-1

Real world evidence confirms that peptides are safe to use. Peptides have a range of well-documented applications in skincare that make them ideal ingredients to formulate with:

  • Peptides derived from legumes have the ability to selectively upregulate positive metabolic genes without stimulating inflammatory markers
  • Peptides can suppress hyperactive melanocytes (pigment-making cells) responsible for skin hyperpigmentation
  • Peptides have been shown to help accelerate wound healing
  • Antimicrobial peptides (AMPs) have been shown to possess anti-microbial properties
  • Hair growth peptides have been shown to stimulate the dermal papilla and keratinocytes associated with hair growth in-vivo

Some key considerations when selecting an effective peptide product include the following:

  • The pH of skin ranges between 4.5 and 5.0. As noted in the Chemists Corner, an online forum where chemists around the world converge to discuss cosmetic chemistry, peptide preparations will typically retain their bioactivity around a pH of 7.0. Myristoyl pentapeptide-17 is kept at a pH of around 7.2
  • Fewer formula modifications. Covalent modifications will often render small proteins biologically inactive.

    How Does MasterGlam AmazeBROW 2-in-1 Brow Serum Pen work?

    The peptide used in Amaze Brow is Myristoyl pentapeptide-17. It acts as a signaling protein that binds to keratinocyte receptors on cell surfaces to encourage thicker, fuller-looking brows. Myristoyl pentapeptide-17 is a short sequence of 5 amino acids that binds to Myristic Acid, a long-chain fatty acid for improved biocompatibility. Panthenol (otherwise known as Pro Vitamin B-5) also helps to form a barrier that protects your skin from external stressors and regulates moisture loss through your skin, a leading cause of dry skin conditions like seborrheic dermatitis.

    Results You Can See and Feel in 6 weeks

    A double-blind placebo-controlled study performed on 24 male and female subjects with long-term Androgenetic Alopecia (AA) found that people who had applied Myristoyl pentapeptide-17 to affected areas had nearly double the percentage of variation of hairs in the anagen (growth) phase compared to the patients who took the placebo after just 1.5 months.

    Peptides are the foundation of the MasterGlam Brand

    MasterGlam Amaze Brow 2-in-1 Tinted Brow Serum Pen contains a proprietary ratio of lipo-oligopeptides, fatty acids, and Pro Vitamin B5 to promote healthy keratin production.

    Directions: Comb the tri-tip applicator through the brows once a day, preferably at night. Replace cap when not in use.

    Stop taking your brows for granted and start giving them the care that they deserve. For brows that look and feel healthier right away and over time, use Amaze Brow 2-in-1 Serum Pen to fill in, define, and nourish your brows in one go.
