ClearSight Lash Serum

A nightly conditioning serum for lashes and brows. Ten organic oils and botanicals — castor, argan, sweet almond, black seed, sea buckthorn, and rosemary — slowly blended into a formula that softens brittle lashes, conditions the delicate skin around the eyes, and supports the appearance of fuller, healthier-looking hair over time.

What it's for

• Sparse, thin, or brittle eyelashes
• Over-plucked eyebrows — the lingering damage from the "skinny brow" era of the 2000s
• Post-lash-extension recovery (when natural lashes come out thinner than they started)
• Brow-area gaps from age, genetics, or past trichotillomania
• Dry, flaky eyelids that make lash-line skincare uncomfortable
• Anyone wanting a natural alternative to prescription lash serums (which can cause iris darkening, eye redness, and eyelid discoloration as known side effects)
• Post-chemotherapy lash and brow regrowth support (consult your oncologist before starting any new product)
• Men and women conditioning beard-edge hair along the lower sideburn line

What's in it

• Cold-pressed organic castor oil — the foundational oil. Ricinoleic acid coats the hair shaft and adds visible thickness. Used for centuries across India, Africa, and the Middle East for hair care.
• Sweet almond oil — lightweight and fast-absorbing. Conditions lashes and soothes the delicate skin around the eyes.
• Vitamin E oil (mixed tocopherols) — natural antioxidant that protects the formula from oxidation and adds gentle nourishment.
• Organic argan oil — the "liquid gold" of Morocco. Rich in vitamin E and essential fatty acids. Softens coarse lash hairs.
• Organic sea buckthorn oil — rich in rare omega-7 fatty acid and carotenoids. Gives the serum its subtle warm hue.
• Organic black seed oil (Nigella sativa) — traditional skin and hair care ingredient used for centuries in the Middle East.
• Organic carrot seed oil — rich in beta-carotene. Conditions the skin around the eyes and contributes to the serum's golden color.
• Organic lavender essential oil — at a low dilution safe for the eye area. Soothes the skin.
• Organic rosemary essential oil — the most-studied botanical in hair-care traditions.
• Aloe vera gel — the cooling, hydrating layer. Calms the delicate eyelid skin.

That's it. No bimatoprost, no prostaglandin analogs, no synthetic fragrances, no parabens, no preservatives.

How to use

1. Remove all eye makeup and clean your lash line thoroughly
2. Wait until your lashes and brows are completely dry
3. Dip the brush wand (or a clean, fine-tip applicator) into the serum — only the tip, don't overload
4. Apply a very thin line across the base of your upper lash line — where the lashes meet the lid skin
5. For brows: brush the serum through your brow hairs in the direction of growth, paying special attention to sparse or patchy areas
6. Avoid getting the serum directly in your eyes
7. Apply nightly before bed
8. Gentle reminder: this is a slow-result product. Commit to at least 8-12 weeks of nightly use.

What to expect

• Texture: medium-bodied oil, thicker than plain castor, absorbs into lash and brow hair cleanly
• Color: warm golden-amber from the sea buckthorn and carrot seed oils
• Scent: subtle — lavender and rosemary with a soft herbal base. Safe distance from the eye to avoid irritation.
• Feel: a hint of cooling from the aloe vera gel and menthol-adjacent notes in the rosemary
• Realistic timeline: immediate conditioning and shine within the first week; softer, less brittle lash hairs by week 3-4; visible appearance of fuller lashes and brows with 8-12 weeks of consistent nightly use. Lash and brow hair grows slowly — there are no shortcuts.
• Bottle life: one bottle lasts 4-6 months of nightly use (a little goes a long way)
• What this is NOT: a medical treatment for lash/brow loss. If you're experiencing sudden or significant loss, see a dermatologist to rule out conditions like alopecia areata or hypothyroidism. This serum supports the appearance of healthier lashes and brows — it's not a cure for medical hair loss conditions.

From a customer

"I use the ClearSight Lash Serum on my lashes and eyebrows every night before bed. As a victim of the 2009 over-plucked eyebrows, my natural brows have never grown back right. In just a month's time, eyebrow hair is growing back in places I thought I'd never see again. And as for my lashes, baby hairs everywhere! I've noticed volume and length added to my lash line, and I feel so beautiful. This stuff is glorious and gets to WORK."

Pairs with

For complete eye-area care, pair nightly with our Caffeine Charged Eye Repair — apply the eye repair balm to the orbital bone first for depuffing, then apply this lash serum directly to the lash line. Both products share the same family of conditioning oils (sea buckthorn, black seed, vitamin E) and layer beautifully without pilling.

The craft

Blended in very small batches in Oakdale, California. Castor oil serves as the base; the remaining oils are added at low temperature in carefully measured proportions to preserve their active compounds. The aloe vera gel is incorporated last. Each bottle is hand-filled, hand-capped, and packaged in premium amber glass with a precision wand applicator to protect the light-sensitive oils. Shelf life 12+ months unopened, 6 months after opening.
