Foltene 4X Fuller Eyebrow Growth Serum, 4 mL, with Peptides and Vitamin B5

For brows that look thin, sparse, or over-plucked, Foltene 4X Fuller Eyebrow Growth Serum adds a lightweight care step to a daily routine. Its formula combines peptides, vitamin B5, and other conditioning ingredients. The serum is also intended for sparse-looking areas at the hairline, temples, and beard. Made in Italy, it is described as 97% natural origin.

Why it makes sense

This serum is designed to support the appearance of fuller, more defined brows while conditioning brow hairs. That makes it a practical alternative to relying on brow makeup alone: use it as a care step, then keep makeup in your routine if you want added definition. Its use also extends beyond eyebrows to sparse-looking areas along the hairline, at the temples, or in the beard, for both men and women.

A 56-day placebo-controlled clinical study evaluated the eyebrow serum and reported increases in hair diameter, length, brow density, and hair count. The reported changes were 6.6% for diameter, 8.7% for length, 8.3% for density, and 7.1% for hair count. These results give shoppers specific context for the product’s fuller-brow positioning, while consistent daily use is the intended approach.

What matters most

The formula includes Myristoyl Pentapeptide-17, panthenol (vitamin B5), hydrolyzed keratin, millet seed extract, and marine algae extracts. Together, these ingredients are presented as conditioning care for brow hairs and support a healthier-looking appearance. The lightweight, non-greasy texture dries quickly and is designed to fit into both morning and evening routines, including before eyebrow makeup.

The 4 mL size keeps the product focused on targeted care rather than broad-area use. For a typical routine, apply the serum as your brow-care step and allow it to dry before continuing with makeup. The same product is positioned for other sparse-looking facial-frame areas, so it may suit someone who wants one serum for brows and a receding-looking hairline or patchy beard. Choose it for a targeted serum format and conditioning ingredients, choose a makeup-only approach when the goal is immediate cosmetic definition rather than a daily care step.

Everyday use

Use consistently as part of your morning and evening routine. Its quick-drying, lightweight feel makes it straightforward to place before brow makeup or other routine steps. Consumer study feedback reported that all participants found it easy to use, while 85% described the texture as lightweight. This feedback speaks to routine usability, not a guaranteed result for every person.

For brows, the product is aimed at areas that appear sparse after over-plucking, grooming, or with age. For the hairline, temples, or beard, it is intended for targeted use where a fuller-looking appearance is desired. Keep the routine simple and regular, and use the serum as a conditioning step rather than treating it as brow makeup.

Final verdict

Foltene 4X Fuller is a focused choice for people who want a lightweight serum for sparse-looking brows, with additional intended use at the hairline, temples, and beard. Its peptide- and vitamin B5-enriched formula, quick-drying texture, and study-backed brow measurements make it especially relevant for a consistent daily care routine. The 4 mL format is suited to targeted application when the priority is supporting a fuller-looking appearance while conditioning the hairs.
