FAQs
1. What happens if I stop using these serums?
Your lashes will eventually return to their original length and thickness. Lash serums extend the growth cycle of your hair follicles. Once you stop applying the product, new lashes will grow back at their genetically determined baseline. To maintain your long results, most brands like recommend scaling down to maintenance use (2–3 times a week) once you reach your target length.
2. How long do I actually have to wait to see results?
You need to be patient. While some lucky users notice a difference in 4 weeks, it takes a full 8 to 12 weeks of daily, consistent use to see the maximum dramatic effects. This timeline aligns with your natural lash shedding and growth cycle.
3. Can I use these serums if I have lash extensions?
Yes, but check the base. NUNA and BABE ORIGINAL are water-based and peptide-heavy, meaning they are 100% safe for lash extensions because they will not dissolve the medical-grade extension glue. In fact, using them while wearing extensions keeps your natural roots strong enough to hold the extra weight.
5. My eyes are burning/itchy. Am I applying it wrong?
Probably. The number one cause of lash serum irritation is over-application. You only need one single dip of the brush for both eyes. Wipe the excess product off the rim of the tube and swipe it like a very thin line of liquid eyeliner right above your upper lash line. Never apply it to your bottom lashes, as it will inevitably bleed directly into your eye while you sleep.
6. Can these serums be used on my eyebrows too?
Yes, but some work better than others.
- The Best Double-Duty Option: The NUNA Eyelash Growth Support Serum is specifically formulated and labeled for both eyelashes and eyebrows.
- The Rest: Serums like GrandeLASH-MD and Babe Original will technically work on eyebrows because brow hairs also respond well to peptides and nutrients. However, because eyebrow skin is thicker, you will get much faster and better results using dedicated brow serums (like GrandeBROW), which feature a thicker applicator brush and a higher concentration of active ingredients.
7. How often should I apply it?
Apply your serum once a day, preferably at night.
- The Golden Rule: More is not better. Applying it twice a day will not speed up your lash growth; it will only cause skin irritation, redness, and waste your product.
- Maintenance Phase: Once you achieve your dream length (usually after 3 months), you can drop your usage down to 2 to 3 times a week just to maintain the results.
8. What is the best way to apply it so it actually works?
Consistency and clean skin are key.
- Cleanse: Wash your face completely. Make sure your eye area is totally dry and free of oil or makeup remover residue.
- Dip Once: Dip the wand into the tube once. Wipe any excess liquid off the tip onto the rim. One single dip is enough for both eyes.
- Swipe: Swipe the brush along the skin of your upper lash line, right where the hair meets the root (exactly like applying liquid eyeliner).
- Dry: Let it dry for 2 to 3 minutes before applying any night creams or going to sleep.
9. Can I apply it to my bottom lashes?
No, never apply lash serum directly to your lower lash line. The skin there is incredibly thin, and the product will inevitably bleed directly into your eyes while you sleep, causing severe irritation, redness, or waking up with puffy eyes. Don’t worry—when you blink, a tiny amount of the upper lash serum naturally transfers to your lower lashes anyway.
