WHEN DO I USE THIS IN MY ROUTINE? Step 2 - right after cleansing. Use AM and PM before treatments or moisturiser. For extra glow, pair with Omega Water Cream. Always follow with SPF in the morning.

IS THIS SUITABLE FOR EVERYDAY USE? Yes, gentle enough for daily AM and PM use. Suitable for all skin types, even sensitive skin.

CAN I USE THIS GLOW SERUM WITH RETINOL AND VITAMIN C?Yes. Absolutely! This exosome serum works beautifully with retinol, vitamin C, and all actives (AHAs/ BHAs). Layer after cleansing, before other treatments.

CAN I WEAR MAKEUP OVER IT? Absolutely. Just wait 30–60 seconds after applying to let it absorb.

DO I NEED HYALURONIC ACID TOO? Not really. This already hydrates like a pro! But if you want both: use Hyaluronic Acid Serum in the AM and Exosome Serum in the PM - or layer if you love the hydration hit.

WHAT ARE EXOSOMES? Tiny messengers that tell your skin to do better. More collagen, less redness, faster repair. Think glow-up at a cellular level. Learn more about Exosomes in Skincare here.

WHAT MAKES INKEY’S EXOSOMES DIFFERENT? They’re plant-derived and clinically proven to: reduce the visible sign of skin strees by 55%*** & increase skin renewal activity by 63% in just 8 hours***. Smart skincare that works harder, deeper, faster.

DO EXOSOME SERUMS ACTUALLY WORK? Yes - when the exosomes are the right type, concentration, and source. Our plant-derived Cica Exosomes are backed by in-vitro testing showing measurable cellular changes in 8 hours, and a 4-week clinical study in which 100% of participants saw more glowing skin. The 6-in-1 formula means you're also getting Hyaluronic Acid, Kollaren™, Ectoin, Q10, and Prickly Pear working alongside the exosomes - so it's not just the exosomes doing the heavy lifting.

WHAT MAKES PLANT-DERIVED EXOSOMES DIFFERENT FROM OTHER EXOSOME SERUMS? Most exosome serums on the market use exosomes derived from bacterial fermentation or animal sources. INKEY's exosomes are plant-derived - specifically from Cica (Centella Asiatica), one of the most clinically studied soothing botanicals in skincare. This gives them a biocompatible, gentle profile with targeted skin-stress reduction benefits. In vitro testing shows a 55% reduction in pro-inflammatory markers and 63% improvement in skin renewal in just 8 hours — results that stand up to scientific scrutiny, not just marketing.

HOW MUCH EXOSOME IS IN THIS SERUM? 1% - and we tell you that upfront. Some exosome serums market themselves using exosome counts (in the billions) rather than concentrations - a metric that sounds impressive but doesn't tell you how much is actually in the formula. We disclose 1% Cica Exosomes because transparency is fundamental to how we formulate.

WHERE DO THE EXOSOMES COME FROM? Plant-based. Sourced from Cica Extract.

WHAT DOES AN EXOSOME SERUM DO FOR YOUR SKIN? Exosomes are nano-sized messengers that communicate with your skin cells - triggering collagen production, reducing inflammation, and accelerating repair and renewal. Think of them as biological signals that tell your skin to perform better. Our plant-derived Cica Exosomes specifically signal a 300% increase in collagen-related gene expression, 55% reduction in inflammatory markers, and 63% increase in skin repair activity - all measured in controlled testing.

IS THIS THE BEST HYDRATING SERUM FOR GLOWING SKIN? Clinically proven - 100% of users saw more glowing skin in our 4-week study*. This brightening hydrating serum delivers both instant glow and long-term skin improvement.

ARE EXOSOMES SAFE? Yes - non-invasive, biocompatible, and gentle on skin. Still patch test to be sure.

IS IT STILL EFFECTIVE WITHOUT MICRONEEDLING? Yes. No needles needed. Our Exosomes are tiny enough to penetrate skin solo.

IS THIS A GOOD ALTERNATIVE TO EXPENSIVE EXOSOME SERUMS? Yes. Premium exosome serums can retail for £70–£100+. At £20 / 30ml, INKEY's Exosome Hydro-Glow Complex delivers clinically proven results - 100% glowing skin in 14 days - with full ingredient transparency at a fraction of the price. For those who want to go further, pairing it with our PDRN Serum (£18) gives you a complete cellular renewal and PDRN stack for £38 total.

CAN I USE THIS WITH MY PDRN SERUM? Absolutely. For maximum skin renewal, layer INKEY's PDRN Serum first (as it's water-based and thinner), followed by the Exosome Hydro-Glow Complex. Together they cover cellular renewal, skin repair, barrier support, and glow — a clinic-level combination at an accessible price.

CAN I USE IT ON SENSITIVE SKIN? Yes. Clinically tested and safe for all skin types, even sensitive.

DOES IT CONTAIN SPF? No. Layer with SPF in the AM - we recommend our Dewy SPF 30.

IS IT NON-COMEDOGENIC? Yes.

IS IT VEGAN? Yes. Certified by The Vegan Society.

IS IT PREGNANCY OR BREASTFEEDING SAFE? Yes

TAKING PRESCRIPTION MEDS? Check with your doctor first - especially if using Roaccutane.

WHAT’S THE PH LEVEL? 6.0–6.5

WHEN WILL I SEE RESULTS? You’ll notice glow after one use. Full results kick in after 14 days: firmer, plumper, more radiant skin with less redness and better bounce.
