RADIANCE WITHOUT THE DRAMA.
A stabilised Vitamin C moisturiser that delivers serious glow without the sting. This silky face cream brightens and hydrates in one smart formula – proven to boost radiance* while keeping even sensitive skin happy. Our clever stabilised Vitamin C works with upcycled Bilberry extract to repair and protect, wrapped up in nourishing plant butters that sink in fast. High-performance actives that actually respect your skin. Novel concept, we know.
Here's the science bit: Traditional Vitamin C (Ascorbic Acid) is brilliant but temperamental. It needs a low pH to work, which irritates skin, and oxidises faster than you can say "orange face cream". Not ideal.
We use Ascorbyl Tetraisopalmitate – a natural, oil-soluble form that releases slowly and stays stable from first pump to last. Paired with omega-rich Bilberry extract (rescued from juice production), it calms inflammation while strengthening your skin barrier.
Add Hyaluronic Acid for bounce, prebiotic Inulin to balance your skin's microbiome, and zero-waste botanical oils for that perfect, never-greasy finish. This is what happens when sustainability meets skin science. Certified organic, dermatologist approved, irritation-free brightening for all.
Vitamin C
If you have a dull, uneven skin tone, this powerhouse is for you. Antioxidant Vitamin C - AKA Ascorbic Acid - is well known for its skin-brightening benefits. We source ours from corn, which is then stabilised in a high percentage that slowly releases on the skin for maximum results.
Hyaluronic Acid
A sugar the body naturally produces, Hyaluronic Acid can hold between 10 and 50 times its weight in water, storing it like a reservoir for the skin – giving a long-lasting, moisturising effect. Our all-natural form comes from maize.
Upcycled Bilberry Extract
Soothing wild Bilberry is rich in fatty acids which help to form ceramides, one of the building blocks of the skin barrier. CO2-extracted, it’s upcycled from seeds from agricultural, food and juice industries – because we’d never let the best of nature go to waste.
Zero-waste Botanicals
Organic Camellia Oil and Mango Seed Butter keep skin oh-so-soft. These raw materials are grown for their oils; any waste is carefully managed and used for animal feed or as a natural fertiliser – meaning no landfill.

"I use this moisturiser nearly every morning, it’s my favourite. I love the consistency. It’s light but very effective on my skin as it matures. It is glowy and doesn’t clog my skin. I use the Pai serum and drops too. Sometimes I just use it on its own after spraying and eye care if I feel my skin needs less products"
"My first time trying this moisturizer for my dry, sensitive skin with rosacea. It hydrates and brightens without irritation and I use it in the morning before makeup. Love the consistency. Would purchase again."
"I can genuinely say this is a fantastic moisturiser. It smells great and the results speak for themselves. I will never swap brands now."
"I've been using this moisturiser for the last 6 months. I love the smell and texture of it. It spreads easily on the skin and it does not leave a film on the skin, which I love. The light texture and smell make me want to put it on more than anything. I also feel like my skin feels more even and my little blemishes not so prevalent."
"Light texture. Bright skin effect. Natural ingredients without the nasty chemicals of most cosmetics. This is my go to moisturizer along with Vitamin C drops for extra brightness!"
"This is the best moisturiser I’ve ever used. My skin looks nourished and flawless. I’ve been using it for a couple of weeks already and can’t be more than happy. I am definitely going to repurchase it 🌸"
"I’ve been using Pai since the launch. I was 53 in August and felt like I needed a glow-up. I switched to C-2 Believe and added the Retinoid booster. So many people have commented on how great my skin looks. I’m so happy with the result."
