hyaluronic acid serum

Pestle & Mortar Cosmetics is a popular brand in the UK and Ireland. They recently launched their Pure Hyaluronic Serum in the United States. I was lucky enough to meet with the founder of the innovative company, Sonia Deasy, to learn all about it and try it for myself.

Sonia Deasy is a mother of five who has always had a passion for beauty and wellness. While managing her husband’s portrait studio in Ireland she noticed how dry, dull and patchy people’s skin looked up close. This sparked her interest in creating a skincare formula that could act as a natural “filter” to decrease the appearance of fine lines and deliver long-lasting hydration.

Sonia’s sister holds a degree in biochemistry and a master’s in science so she asked her to develop a formula made up of ingredients that would produce immediate, camera-ready results. Once the first prototype was created Sonia gave it to some of the world’s leading photographers, friends and family to try. The feedback she received was unanimous — everyone loved it. From there, Pestle & Mortar and Pure Hyaluronic Serum were born.


I’ve tried a few different hyaluronic acid serums and they can often be sticky and take upwards of 10 minutes to fully absorb into my skin. After applying just one drop, I could tell that Pestle & Mortar’s Pure Hyaluronic Serum was different. The lightweight, fragrance-free formula fully absorbed into my skin almost immediately, giving my face radiant, silky finish free of dullness and fine lines.

Hyaluronic acid is a carbohydrate that occurs naturally throughout the human body. When we are young our skin contains large amounts of it but as we get older our ability to produce it decreases. Hyaluronic acid is a powerful moisturizer that’s commonly used in skincare for its anti-aging benefits. It reduces wrinkles by plumping skin and boosting hydration. It also works to prevent moisture loss and lock in moisture by reinforcing the skin’s barrier function.

Pestle & Mortar’s Hyaluronic Acid Serum is suitable for all skin types. All it takes is two drops in the morning and at night and you’ll have visible results within three days. It also makes a great primer, giving makeup a flawless finish that lasts all day. I’d even recommend adding a drop to your foundation to give your skin an a gorgeous glow and an even bigger boost of radiance.

Pure Hyaluronic Acid Serum sells for $69.99. It’s available at Pestle & Mortar and shipping is free anywhere in the United States.
