Frequently Asked Questions

Can I use this serum if I have eyelash extensions or a lash lift?

Absolutely. Our water-based formula won’t weaken extension adhesive. It’s ideal for "Post-Lash Care" to hydrate and nourish lashes dried by chemical treatments, ensuring your lift or extensions look better and last longer.

Does this contain Prostaglandins?

I'm worried about dark circles or eye discoloration. Our serum is 100% Prostaglandin-free, meaning no risk of pigmentation or discoloration. Unlike products that overstimulate blood vessels, our formula is safe for daily use on lashes and brows without irritation. Just healthy, natural growth.

My eyes are very sensitive. Will this cause any stinging or burning sensation?

No, it’s designed for a "No-Sting" experience. Our formula is pH-balanced (7.0) to match human tears, making it gentle enough for day and night use. Expect visible results in 2 weeks, with peak vitality and fullness achieved in 3 months.

Is it okay to apply mascara after using the serum in the morning?

Yes. Our lightweight, fast-absorbing serum leaves no sticky residue. Simply wait 30 seconds to dry, and you can apply makeup as usual. It even acts as a nourishing primer to protect your lashes throughout the day.

Can I use this on my eyebrows as well?

Definitely. Eyebrow follicles share a similar structure to lashes. Use the dual-tip applicator’s ball tip to target sparse areas. The high concentration of Biotin and Peptides effectively revitalizes and thickens your brows too.

My lashes look fuller

I use it every night before bed. My lashes look softer, fuller, and more noticeable, especially when I apply mascara.

Maya
★★★★★

Lightweight and easy

It dries quickly and does not leave my lash line feeling sticky. I can use it in the morning and still do my makeup as usual.

Harper!!

Helped after extensions

My lashes looked thin after taking off extensions. This serum became my recovery step, and they look smoother and healthier now.

Gentle on my eyes

Easy to use every day

The clear texture is simple and clean. I just apply it along my lash line, let it dry, and continue with my routine.

Mascara goes on better

My lashes feel more conditioned, so mascara applies more evenly. They look lifted and less brittle than before.

I use it on brows too

I started using the extra product on sparse areas of my brows. It is simple, clean, and easy to control with the applicator.

Perfect after my lash lift

My lashes can feel dry after a lift. This keeps them looking softer and more polished without weighing them down.
