Why prostaglandin-free matters

Many popular lash serums rely on prostaglandin analogs. They can be effective, but they are also linked to side effects some people want to avoid, like irritation and darkening of the skin around the eyes or, in some cases, changes to eye color. FACTORFIVE takes a different approach, using growth factors, peptides, vitamins, and botanicals that condition and strengthen the look of lashes and brows without prostaglandins.

Key ingredients

• Human stem cell conditioned media: FACTORFIVE's signature growth factor ingredient.
• Biotin and panthenol: vitamins well known in hair care for conditioning and strengthening the look of hair.
• Ocimum basilicum (basil) hairy root extract: a botanical included to support thicker-looking lashes and brows.
• Copper tripeptide and myristoyl pentapeptide: peptides that support healthy-looking lashes, brows, and skin.
• Niacinamide, caffeine, and green tea: supporting ingredients that care for the delicate skin along the lash line and brows.

How to use

Start with clean, completely dry lashes and brows. Using the precision brush, apply with light, feathering strokes along the upper lash line from the inner to the outer corner, and to sparse areas of the brows. Avoid the waterline and lower lash line. Use morning and night for best results, and follow the directions on your package. Consistency matters, so try not to skip applications.

Building your routine

1. Cleanse gently around the eyes with a mild cleanser like Barrier Pro 1-Step Cleanser.
2. Enhance lashes and brows with FACTORFIVE Lash/Brow Serum.
3. Care for the eye area with FactorFive Eye/Lash Cream.
4. Protect every morning with a broad-spectrum sunscreen like Face Reality PowerMineral SPF 50.

Frequently asked questions

How long until I see results?
FACTORFIVE reports noticeable results in as little as 4 weeks in VISIA® product trials. Lashes and brows go through natural cycles, so keep applying consistently for several weeks before judging.

Will it change my eye color?
No. The formula is prostaglandin-free and won't alter eye color.

Can I use it with lash extensions or a lash lift?
Ask your lash artist first. Water-based serums near the lash line can affect extension adhesive. After a lash lift with us, wait until the first 24 to 48 hours have passed before applying anything to the lashes.

Can I use it on my brows?
Yes. Focus on sparse spots and the outer third of the brow, where brows often look thinnest.

What if my eyes feel irritated?
Stop using it and rinse with water. If irritation continues, check with your healthcare provider.

Can I use it while pregnant or nursing?
Please check with your healthcare provider before starting any new product during pregnancy or nursing.

Esthetician tip

Apply at the same times every day, such as right after brushing your teeth, so it becomes a habit. A lash lift or brow service with us plus a consistent serum routine is a great way to keep lashes and brows looking their best. Ask us at your next appointment.
