Pestle & Mortar

Pestle & Mortar is an independent Irish skincare company based in Naas, County Kildare. It was founded in 2014 by Sonia and Padraic Deasy, a married couple who launched the brand from their home with a single product, the Pure Hyaluronic Serum [10]. The company remains founder-led and, according to the brand, is now stocked in more than twenty countries.

The brand takes a deliberately pared-down approach to skincare, pairing a small range of hydration-focused formulas with a "less is more" philosophy. It describes its products as combining the traditions of Indian natural healing with modern cosmetic science, and continues to trade actively.

Before Pestle & Mortar, Sonia and Padraic Deasy ran a portrait photography studio together. Through their work behind the camera, they observed that many clients struggled with dull, flaky skin without knowing how to address it — an observation the couple has said inspired them to move into skincare [8]. They launched the company in 2014 from their home in County Kildare, choosing to release just one product to begin with rather than a full range.

Sonia Deasy, who serves as chief executive, attributes the brand's formulating approach to her family background. She has described her formulas as "inspired by my six-generation heritage in Indian natural healing" [8]. The company was built without outside investment: in interviews the founders have described it as revenue-funded, which they say gave them full control over decisions and the independence to move quickly.

Pestle & Mortar positions itself around simplicity. "Less-is-more has always been my approach — effective ingredients, simple routines, beautiful results," Sonia Deasy has said of the brand's ethos [1]. Its stated mission is "to enhance and protect that natural beauty," and it markets itself under the tagline "Simple solutions for beautiful skin" [1].

The company frames its formulas as blending "the ancient wisdoms of Indian natural healing with cutting-edge science." In its own materials it emphasises kind-to-skin formulas and proven active ingredients over an extensive product catalogue, and it organises its range around specific skin concerns such as dehydration, ageing, hyperpigmentation and rosacea.

The brand was built on the Pure Hyaluronic Serum, which was its sole launch product and remains its signature item. The serum uses hyaluronic acid at several molecular weights; the company explains that smaller molecules penetrate more deeply to replenish moisture and support the skin barrier, while larger molecules form a breathable layer on the surface. Its supporting ingredients include panthenol (pro-vitamin B5), cucumber extract and aloe vera, and the brand states the hyaluronic acid it uses is Ecocert and Cosmos certified [3].

Beyond the serum, Pestle & Mortar sells cleansers, moisturisers, masks, toners and eye and lip care, alongside a "Derma" line covering face, body and hands. The catalogue has grown over time; the brand's collections page lists dozens of products and has recently promoted a "Pore Reset Pads" launch.

The company's sustainability messaging centres on the idea that customers "shouldn't have to choose between beautiful skin and a healthy planet." It states that its formulations are vegan and cruelty-free and that it bans more than 3,000 ingredients from its products [3]. The brand is approved by PETA and carries a "Guaranteed Irish" mark.

Pestle & Mortar says roughly 80% of its production takes place locally in Ireland, which it links to reducing its carbon footprint and supporting the local community [3]. On packaging, the company reports replacing plastic shipping materials with recycled paper and eliminating single-use boxes, while acknowledging that some sustainability changes involve trade-offs and framing its progress as incremental.

Having started from the Deasys' home, the business expanded its operations over its first years of trading. In 2019 it moved into new premises of about 929 square metres (10,000 square feet) and won the Local Enterprise Offices' National Enterprise Award that May [9]. By the mid-2020s the brand described itself as celebrating over a decade in business, stocked in more than twenty countries.

Distribution has spanned several international channels. Interviews have noted the brand's presence on the QVC shopping channel, in 45 Marks & Spencer locations in the United Kingdom, and at Harvey Nichols in Hong Kong [9]. More recently the company expanded into the Baltic region, with products reaching Estonian stores in late 2024 and further availability in Latvia and Lithuania.

The Pure Hyaluronic Serum drew early editorial attention. In 2015 the beauty publication Into The Gloss reviewed it under the headline "The Hyaluronic Acid Serum To End All Other Hyaluronic Acid Serums," with the reviewer calling it her "pared-down, all-in-one" [7]. The write-up helped establish the serum's reputation as the product the brand was built on.

In business terms, the company won the National Enterprise Award in 2019 [9], and its founder was a finalist in the EY Entrepreneur of the Year Awards. In 2025 the brand won two awards at Estonia's Anne & Stiil Ilulemmikud beauty awards [10].

Pestle & Mortar remains active and independently owned. Its most recent visible activity includes an August 2025 feature in the Irish Farmers Journal, the 2025 Estonian awards, and current product launches on its website [10]. The brand continues to operate from Naas under its founders.
