For over a decade, I've built my career as a PMU artist by staying up to date on the latest and greatest in the beauty industry. Today, peptides are one of the most talked-about ingredients. But how do peptides work for eyebrow hair support specifically?
Peptide-based formulas, such as FATBROW The Serum, can help support healthier-looking brows by improving the environment around the hair follicle and supporting the appearance of stronger, fuller hairs over time. The magic happens when consistency meets the right ingredients.
What Are Peptides?
Peptides are short chains of amino acids that help support many natural processes within the skin and hair. Think of them as little messengers that help encourage healthier-looking conditions around the hair follicle.
In brow serums, peptides are commonly used to help support:
- the appearance of fuller brows
- stronger hairs
- softer texture
- healthier-looking follicles
- reduced appearance of thinning
Peptides are gentler on the skin than common "hair growth" ingredients like prostaglandin analogs and retinols used in leading brow and lash serums. We carefully selected a custom blend of peptides for FATBROW The Serum with our goal being full, fat brow hairs without the irritation.
Peptides vs Prostaglandins: What’s the Difference?
One of the biggest conversations in brow and lash care today is the difference between peptide-based formulas and prostaglandin-based formulas. Prostaglandin analogs are sometimes associated with irritation, sensitivity and discoloration around delicate eye and brow areas. Prostaglandins are also linked to discoloration and premature fading of permanent makeup. Since they cause skin irritation, permanent makeup artists are not able to tattoo on skin that uses serums with prostaglandins or retinols.
This was our main reason to create a serum that was different.
Peptides, on the other hand, are often chosen for a gentler approach focused on supporting healthier-looking hair over time. That’s why FATBROW The Serum was intentionally formulated without prostaglandins.
How Long Do Peptides Take to Work?
I've said it before, and I'll say it again: consistency is everything. Many users of The Serum begin noticing early improvements within a few weeks, while fuller-looking results often become more visible around weeks 8–12. Brow growth is a process, not a one-day transformation.
The best results happen when you:
- apply consistently morning and night
- avoid overplucking
- support the skin barrier
- stay patient with the process
Healthy-looking brows are built over time. Check out the below results after 10 weeks of using FATBROW The Serum.
