How to use

HOW TO APPLY
Essential Lash Serum
Use only as instructed. Apply serum in the PM on clean, dry skin. One dip of the wand is enough for both eyes. Wipe excess product from brush before applying & use a single stroke on the eyelid above the upper lash line, taking care not to get serum in eye. Do not apply to lower lash line. Avoid getting serum in eyes; if so, immediately rinse thoroughly with cool water to remove serum from eye. Allow 2-3 minutes for serum to fully dry before applying other products or lying down. Once satisfied with results, use 2-3 times a week to maintain your look. This product contains a small amount of isopropyl cloprostenate, a synthetic prostaglandin analog. See directions & warnings inside the box.

Densifying Hair Serum
1. Use one full dropper in the PM across three sections of your scalp; left, middle and right. Dropper is marked with how much formula to use per section.
2. Use the pointed tip of the applicator to part hair, applying serum directly to the scalp to each designated section.
3. Massage product into scalp. Do not rinse.

HOW OFTEN TO USE
Apply each treatment daily. Once satisfied with results, use 2-3 times a week to maintain your look.

Essential Lash Serum beginners should apply serum every 2-3 days and work up to nightly use once eyes are used to the product.

WARNING: For external use only. Keep out of reach of children. Only apply with applicator. Do not share applicator. Secure lid tightly after each use. Avoid getting in eyes; if so, immediately rinse with cool water. Do not use if pregnant or nursing, undergoing treatment for glaucoma or cancer, or if you have ever experienced conjunctivitis, dry eyes, eye infections, styes, irritation from other cosmetics applied in the eye area, or any eye-related disorder or illness.

Reviews

Lash serum

"I absolutely love this product!! My eyelashes have never been longer or fuller!! I highly recommend and I am stocked up too."

Michelle c. (5/5)

My holy grail

"I’ve been using this set for over a year now, and I can honestly say it’s been a staple in my routine. The lash serum is gentle, easy to apply, and never irritates my eyes — I’ve noticed my lashes look healthier and fuller over time. But the real standout for me is the hair serum. After going through months of aggressive chemo, my hair took a huge hit, and I struggled to find something that actually helped without feeling heavy or damaging. This has truly been my holy grail. It feels lightweight, doesn’t leave buildup, and has made a noticeable difference in how my hair feels as it’s grown back — stronger, healthier, and easier to manage. I don’t say this lightly, but this set has been part of my recovery and confidence journey. If you’re dealing with hair thinning or regrowth, I highly recommend giving it a try."

Charli W. (5/5)

Locks and Lash Set

"This eyelash serum is the best. I have been using it for over two years now and my eyelashes are so long. I barely wear mascara because it grows them out beautifully. The hair serum has not shown me any results yet but I have not been using it for that long yet."

Lash and hair serum duo

"Lash serum is ABSOLUTELY AMAZING!! I saw results in as little as 2 weeks! The hair serum is AMAZING as well, consistency is key and I have gradually seen new growth on the sides of my scalp. LOVE this company and I am so HAPPY I found them! ❤️"

Sadly, no difference

"I've been using the lash serum for 3 months and sadly found no difference in my eyelashes. I'm only about 6 weeks into the hair serum. Of course nothing noticeable yet but I'm certainly hoping"
