The Science of Growth

Multi-Peptide natural
growth complex.

Acaia harnesses a powerful multi peptide complex designed to work at the root of your lashes. Our formula combines growth stimulating actives to extend the Anagen phase increasing lash length projection, conditioning ingredients to strengthen and protect overall lash health, and root nourishing compounds to create an optimal environment for sustained lash length and a reduction on lash breakage during the Telogen phase.

Key Ingredients

Formulated with
the finest.

Every ingredient is purposefully chosen and ethically sourced.

Growth Stimulating Actives

Biotin (Vitamin B7)

Essential Protein Builder

Essential for keratin production — the protein that makes up lashes and brows. Supports the hair growth cycle and helps reduce brittleness. Deficiency is linked to hair thinning, so topical application ensures follicles have what they need locally.

Panthenol (Provitamin B5)

Conditioning Agent

A humectant that penetrates the hair shaft, improving moisture retention, flexibility, and thickness. Reduces breakage so lashes retain their length, while soothing the delicate skin around follicles.

Peptides (Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1)

Follicle Signalling

Short chains of amino acids that signal follicle cells to ramp up keratin production. Extend the anagen (growth) phase of the hair cycle, resulting in longer, thicker lashes and brows over time.

Prostaglandin Analogues & Lipid-Based Actives

Growth Phase Extender

Mimic natural prostaglandins that regulate the hair growth cycle. Extend the growth phase and increase the number of hairs in active growth simultaneously. Very effective for visible results.

Conditioning Ingredients

Hyaluronic Acid

Deep Hydration

Draws and holds moisture around the hair follicle and along the shaft. Hydrated follicles function more efficiently, and hydrated lashes are less prone to snapping. Creates the optimal environment for growth.

Castor Oil (Ricinus Communis Seed Oil)

Circulation & Conditioning

Rich in ricinoleic acid with anti-inflammatory properties. May improve blood circulation to follicles. Coats and conditions hairs, reducing breakage and giving the appearance of fuller lashes and brows.

Vitamin E (Tocopherol)

Antioxidant Protection

A potent antioxidant that protects follicles from oxidative stress and free radical damage. Supports skin health around the follicle and improves circulation, locking in moisture along the hair shaft.

Keratin

Structural Protein

The structural protein lashes and brows are made of. Topical keratin fills in micro-damage along the hair cuticle, making existing hairs smoother, stronger, and more resistant to breakage.

Follicle Stimulating Ingredients

Niacinamide (Vitamin B3)

Microcirculation Booster

Improves microcirculation to the follicle and strengthens the skin barrier around the lash and brow line. Anti-inflammatory properties create healthier follicle environments for better growth conditions.

Amino Acids (Arginine, Glycine, Cysteine)

Keratin Building Blocks

The literal building blocks of keratin. Supplying these topically gives follicles readily available raw materials for hair synthesis. Cysteine forms the disulfide bonds that give lashes their strength and curl retention.

Caffeine

Growth Phase Activator

Stimulates blood flow to follicles and may counteract DHT effects (a hormone linked to hair miniaturisation). Helps nutrients reach the follicle more efficiently and extends the growth phase.

Collagen

Follicle Foundation Support

Provides structural support to the skin surrounding follicles. As we age, collagen loss weakens the follicular anchor — supplementing it topically helps maintain a strong foundation for lash and brow retention.

Consistency is the key to the results you need.

Acaia lash serum with hourglass on marble
1

Cleanse & dry thoroughly

Remove all makeup, oil, and residue from the lash line. The serum absorbs most effectively on a clean, completely dry skin surface — any moisture or product will act as a barrier.

2

Apply with precision tip

Using the ultra-fine applicator brush, draw a thin, precise line along the upper lash line — as close to the roots as possible, as if applying a fine eyeliner.

3

Allow full absorption

Wait 60 seconds before applying any additional products. Do not rinse off and avoid rubbing the eye area to allow full effect.

4

Maintain for lasting results

Use nightly for a minimum of 28 days for best results. For maintained density and length, continue as part of your permanent nightly ritual — lashes will sustain their improved cycle with ongoing use.
