If you're a fan of Aesop products, you'll be glad to know that the brand is introducing a new skincare category, the concentrate, with its latest product the Lucent Facial Concentrate. The serum has an aqueous viscosity and a matte finish, that is great both for this weather and for people who don't like oil-based products. In the formulation: vitamin C, niacinamide (vitamin B3), sodium carrageenan as well as nourishing oils of rose otto, frankincense and sandalwood. We spoke to Dr Kate Forbes, general manager, products and R&D of Aesop to find out more.

What is special about this new product?
The Lucent Facial Concentrate is the newest addition to our Skin Care + range that gives additional vitamins and benefits to the skin. It can be used as part of a customer's daily routine or when they need something extra. We were trying to make a very lightweight product, particularly for this market. We wanted to incorporate hydration in this product as well as additional benefits of vitamins B and C. This has sodium carageenan — an algae extract — to lock in moisture into the skin and keep it there. It's lightweight, yet intensely hydrating.

How do you apply this product? Are there any other ways to use it?
Use it morning and night depending on your skin type. You can also use it as a layering serum in other climates — apply this first and apply your moisturiser or oil on top. It dries quickly and leaves a matte finish. In Aesop, we talk a lot about blending products to suit your skin's needs. It can be mixed with the Blue Chamomile Facial Hydrating Masque. If you blend this with other products like your hydrators, you'll be adding vitamin B and C into your them.

The product is called a 'lucent' concentrate. What is the effect we'll see on our skin from using this product?
You'll have skin that's in a healthy state. With sufficient vitamins, nutrients and moisturisation your skin will definitely have that natural glow to it.

How does Aesop decide to introduce new products?
We don't launch a lot of products. We think seriously about what we want to release. We only launch a product when it is an interesting one, and not to meet a calendar scehdule. It will typically take at least two years to develop a product. Aesop spends a lot of time in the ingredient research and the testing phases, to make sure each product is safe and effacacious. We certainly have conversations with our customers from around the world, and that does get fed back to us in the research labs. But it is more about identifying a need, rather than merely following a trend.

What are your top three must-haves from Aesop?
I love all the products obviously. For me the essentials are a cleanser, toner and moisturiser. I use the Fabulous Face Cleanser as my daily cleanser. Other personal favourites are the B Triple C Facial Balancing Gel and the Blue Chamomile Facial Hydrating Masque. I'll wear the Blue Chamomile Masque on an airplane — as it is invisible on the skin — just to lock in the moisture, as it's so dehydrating in the cabin. The B Triple C is a nighttime, indulgent treat for me when I feel my skin is a bit duller, as it really gives my skin a vitamin boost. And now, the Lucent Facial Concentrate is a new favourite.
