FAQs

HOW DOES IT WORK? Unlike traditional lip plumpers, this balm boosts volume while protecting your skin barrier and locking in moisture - no irritation, no sting.

THE HERO INGREDIENTS? 6% Tripeptide Complex: Boosts lip volume over time by targeting volume loss for plumper, more defined lips. 2% Ultra Filling Spheres: Dehydrated Hyaluronic Acid absorbs water and expands for instant plumping. Smooths fine lines and locks in moisture.

WHAT HAPPENS IF I STOP USING IT? You’ll start seeing visible plumping in as little as 2 weeks. Keep using at least 3x daily to maintain results.

IS IT STICKY? Nope. Smooth balm texture, not sticky like a gloss.

WILL IT TINGLE/BURN/STING? No tingling, burning or stinging - just plump, hydrated lips.

DOES IT CONTAIN SPF? No.

WHAT DOES IT TASTE/SMELL LIKE? No added flavours - you’ll only notice the natural scent of the ingredients.

CAN I LAYER IT WITH LIPSTICK? Yes! Wear it alone or layer over your favourite lip colour for a glossy boost. (INKEY's founder Colette pairs it with her favourite red.)

CAN I USE IT MORE THAN 3X DAILY? Yes - 3x daily for best results, but reapply as often as you like.

WHERE DOES IT FIT IN MY ROUTINE? Use it as the final step AM + PM, or apply anytime during the day.

IS IT CLEAR OR COLOURED? Clear. Adds a natural sheen that works alone or on top of lipstick.

CAN I USE IT IF I HAVE LIP FILLERS? Yes. Safe to use alongside lip fillers to hydrate, smooth and support lip volume. Always patch test first. If unsure, speak to your GP.

IS IT VEGAN? Yes - certified by The Vegan Society.

IS IT SAFE FOR PREGNANCY OR BREASTFEEDING? Yes

WHAT’S THE PH? No pH - waterless formula.
