A step-by-step lash and brow serum routine using FACTORFIVE Lash/Brow Growth Serum, with checkpoints for clean skin, thin lines, and makeup timing.
Quick answer
Apply FACTORFIVE Lash/Brow Growth Serum to clean, dry skin along the upper lash line and brow area once daily, using a thin line rather than flooding the roots. Let it dry completely before makeup or other eye products.
Why clean, dry skin changes the result
Serum sits on the skin surface, so leftover cleanser, oil, or eye cream can dilute it or move it away from the lash line. If you already use an eye serum or cream, apply it first and wait until it absorbs; the growth serum should be the last skincare step in that area.
The same rule applies to makeup removal. A clean lid also means less chance of transferring bacteria or old mascara into the root area.
Where to expect the serum to help, and where it won't
This is a prostaglandin-free formula built around stem cell growth factors and strengthening botanicals, so it is aimed at visible fullness rather than a dramatic lash-lengthening effect. That makes consistency more important than quantity: a thin daily line is the routine, not a heavy nightly coat.
If your main concern is dark circles or puffiness, this serum is not designed for that job. Keep it on the lash line and brow area, and use a separate eye product for the under-eye skin.
Makeup timing: the step most people rush
Lash serum before makeup only works if the serum has dried. If you apply mascara while the lash line is still wet, the wand can drag serum onto the lashes and clump them. Give the serum a few minutes, then apply eye makeup as usual.
At night, apply the serum after removing makeup and cleansing, and skip mascara entirely so the product stays where you placed it.
Your daily lash and brow serum steps
- Cleanse and fully dry the eye area: Remove makeup and cleanse as usual, then pat the lids and brows dry. Wait until no moisture remains before applying serum. Damp skin can dilute the serum and let it migrate into the eyes.
- Apply eye cream first, if you use one: Apply your regular eye serum or cream to the under-eye area and let it absorb. Keep it away from the lash line so it does not mix with the growth serum. If you skip eye cream, go straight to the growth serum.
- Draw one thin line along the upper lash line: Use the applicator to trace a single thin line at the base of the upper lashes, from the inner corner to the outer corner. Do not flood the roots or repeat for extra coverage. One pass is enough; more product does not speed up results.
- Sweep the brow area in the direction of hair growth: Apply a thin layer along the brow line and sparse areas, following the natural direction of the hair. Avoid rubbing it in circles. Keep the serum on the brow skin, not in the eye itself.
- Let it dry before makeup or bed: Wait a few minutes until the serum is completely dry. In the morning, apply mascara and brow makeup only after this point; at night, go straight to sleep. If mascara clumps, the serum was still wet when you applied it.
Product facts
- FACTORFIVE Lash/Brow Growth Serum: FACTORFIVE Lash/Brow Growth Serum is a prostaglandin-free formula with stem cell growth factors and strengthening botanicals. If you prefer to avoid prostaglandin-based lash products, this gives you a gentler routine to follow with the same thin-line application.
