Nicola Coughlan's skincare routine features this popular serum

Nicola Coughlan swears by this affordable serum from The Ordinary to maintain her glowing skin.

The Bridgerton star is a fan of the popular brand, in particular The Ordinary's Hyaluronic Acid 2% + B5, which is priced at €9.90.

She revealed it during an exclusive video for Vogue, which saw her break down her skincare and beauty routine.

The actor opened up about her "really, really thirsty" skin and the lengths she goes to keep it hydrated and plump.

This includes The Ordinary's best-selling Hyaluronic Acid 2% + B5, which "delivers instant and long-lasting hydration".

There's two to choose from, the original formulation and one with ceramides, with Coughlan using the latter.

The second-generation formulation combines ingredients for enhanced hydration, barrier support, and smoother skin.

While the addition of ceramides provides barrier support while retaining multi-depth hydration benefits.

Fans of the brand also love the serum, with one five star review saying: "My skin went from tired, starting to wrinkle, uneven skin tone, dark spots and freckles to me not using makeup anymore. No more redness, spots, blemishes."

Another wrote: "This serum is really light weight and non sticky compared to the old one. It boosted the moisture and reduced the dehydration in my face."

They also complimented the added ceramides saying it "helped with the moisture barrier".

Somebody else said: "The consistency was perfect for my skin, not too thin and not too thick."

Coughlan's skincare regimen also features a soothing facial massage with the NuFACE toning device, priced from €276.95 and Tatcha's The Dewy Skin Cream for €79, which she praises for its makeup enhancing properties.

Finally there's the Fenty Skin Hydra Vizor Invisible Moisturizer SPF30 for €42 and a refreshing spritz of Evian Facial Spray priced at €8.72.
