Why You'll Love It

FIRMER SKIN, FAST.

Drop a concentrated shot of Phytofill™ into your routine — a 100% natural, two-active formula clinically proven to visibly smooth fine lines in just 24 hours*. No filter, no needles, all natural.

Think of your skin like a fresh sheet of paper. Every smile, frown, and laugh leaves a tiny fold, and as the years stack up, those folds get harder to flatten.

Phytofill works from two angles. A biomimetic film built from tara pod and sea moss lifts and smooths the moment it goes on, while Butterfly Lavender calms the muscle micro-contractions that drive expression lines in the first place. Fewer contractions, fewer creases — so smile freely without giving laugh lines a second thought.

Our Butterfly Lavender is a precise CO2 concentrate rather than a full essential oil. You keep the bioactive that matters — fenchone, which acts as a natural muscle relaxant — without the broad spectrum of volatile compounds that tend to irritate reactive skin. It sits at 1%, the highest dose the supplier has clinically tested, so the active hasn't been watered down to fit fillers in.

Results compound, too. In our consumer trial, 57% reported smoother skin within 2 hours, climbing to 84% by day seven. Supplier clinical testing recorded a 17.4% drop in wrinkle depth at 24 hours, with skin roughness measuring 12.7% lower a week after the treatment ended.

"There's no such thing as Botox in a bottle. But when we discovered this ingredient we had to formulate with it. Using expert CO2 extraction, we've taken the most active part of the plant, which tackles wrinkles with the same principles as injectables – relaxing the muscle to help smooth expression lines. Without irritation, and without any permanent changes to the skin."

Why should I choose Phytofill for expression lines and fine lines?

Phytofill combines two actives on different timescales. The biomimetic biopolymer film tightens and smooths from first application, while butterfly lavender extract at 1%, the supplier's maximum clinically tested dose, relaxes expression lines at their muscular source and progressively reconstructs the epidermis. In an independent consumer trial of 108 subjects, 70% agreed it reduced the look of wrinkles and fine lines after 7 days, and 68% agreed it reduced the appearance of expression lines, both statistically significant.

How do I use this booster in my routine?

Add 1-2 drops to your moisturiser, serum, or face oil and apply as normal, or apply directly to skin before moisturising. It's suitable for face and décolletage, morning and evening. The booster format means you get the full 1% clinical dose of butterfly lavender active without changing the products you already use.

Is Phytofill suitable for sensitive skin?

Very much so. Phytofill is independently 96-hour patch tested on sensitive skin volunteers, fragrance-free, essential oil-free, and non-comedogenic. The butterfly lavender extract is a targeted CO2-extracted concentrate rather than a whole essential oil, so it delivers the specific active compounds without the broad volatile aromatics that commonly trigger irritation in reactive skin.

Is Phytofill safe during pregnancy and breastfeeding?

Yes, Phytofill is safe for use during pregnancy and breastfeeding. It's 100% natural, free from retinoids, essential oils, fragrance, and all other ingredients commonly flagged during pregnancy.

How long do the effects of Phytofill last?

Results build over time and stick around even after you stop. In a supplier clinical trial of 20 volunteers, skin roughness was still reduced by 12.7% seven days after use ended, which points to genuine epidermal reconstruction rather than a temporary cosmetic effect. An independent consumer trial of 108 subjects backs this up: agreement that skin looked smoother rose from 57% at 2 hours to 84% at 7 days, with firmness climbing from 64% to 81% over the same period. Regular use gives the best progressive results.

Can I use Phytofill as a natural alternative to injectables?

That's exactly the thinking behind it. Phytofill targets the same root cause as injectable neurotoxins, repeated muscle micro-contractions, but through a topical, fully reversible botanical mechanism rather than paralysis. A supplier clinical trial on 20 volunteers showed a 17.4% reduction in main wrinkle depth versus placebo at 24 hours. It won't replicate the dramatic freeze of injectables, but for anyone looking for a natural, non-invasive route to visibly softer expression lines, it's a credible option with real data behind it.

Which other Pai boosters work well with Phytofill?

Phytofill pairs especially well with Peptides 5% Smoothing Booster in the evening, since the two target ageing through entirely different mechanisms: Phytofill relaxes expression lines at their muscular source, while Peptides 5% stimulates collagen and elastin synthesis. Add Stabilised Vitamin C 20% in the morning for antioxidant protection, and Bonne Nuit Night Cream at bedtime to address inflammaging overnight.

What is butterfly lavender and how does it reduce expression lines?

Butterfly lavender (Lavandula stoechas) is a Mediterranean species distinct from common lavender. Pai uses a CO2 supercritical extract that preserves fenchone, a bicyclic monoterpene with independently published antispasmodic activity via potassium channel activation (PMID: 35408513). Rather than paralysing the muscle, fenchone eases micro-contractions so the overlying skin can smooth.

In a supplier clinical trial of 20 volunteers aged 46 to 59, twice-daily application at 1% produced a 17.4% reduction in main wrinkle depth versus placebo at 24 hours (p<0.05). The extract also stimulates keratinocyte division and adhesion protein expression, progressively reconstructing the epidermis beneath the lines.

What is the biomimetic biopolymer film and what does it do?

It's an engineered interpenetrating biopolymer network (IBPN) that cross-links two botanical polysaccharides: galactomannans from tara pod (Caesalpinia spinosa), which deliver an astringent tightening effect, and sulfated galactans from elkhorn sea moss (Kappaphycus alvarezii), which form a flexible film that physically fills and smooths fine lines. These aren't simply blended; the patented cross-linking creates a single biomimetic film with superior resistance, flexibility, and adhesion. The supplier has tested this technology across 28 studies on over 1,100 volunteers, confirming its tensor and smoothing efficacy.

What certifications does Phytofill have?

Phytofill is COSMOS Natural certified by the Soil Association, Leaping Bunny certified cruelty-free, and registered vegan. It's also independently 96-hour patch tested on sensitive skin volunteers, which goes beyond standard industry requirements. The formula is 100% natural origin and RSPO palm certified.

What makes Phytofill different from peptide-based or retinol firming products?

Most topical firming products use synthetic peptides that modulate neurotransmitter release at the neuromuscular junction, or retinoids that accelerate cell turnover. Phytofill works through a different pathway entirely: its butterfly lavender extract directly and reversibly inhibits muscle micro-contractions, confirmed in supplier in vitro testing on a validated motoneurone/muscle cell co-culture model. The inhibition reversed completely when the extract was removed, confirming it eases contraction rather than blocking it permanently. Because the mechanisms don't overlap, Phytofill can be layered with peptide-based products for a multi-pathway approach.

Q&A

Hi cam I use this wit niacinamide, and matrixyl? is it safe to be used on rosacea skin? Is it better used morning or night?: Hi Sonia! Our Phytofill™ Booster is compatible with Niacinamide and Matrixyl and has been independently patch-tested to ensure suitability for sensitive skin. It can be used both morning and evening, but if you prefer to use it once a day we recommend using it in the evening. This will boost the natural repair process when your skin is the most relaxed. We hope this helps! Pai Customer Experience Team
