Whether you want anti-ageing, acne-fighting or hydrating skincare, you’ll find the perfect serum from our collection. Read our expert recommendations from a range of popular Irish and global brands.

Hyaluronic acid

The most popular hydrating factor occurs naturally in the skin and is responsible for maintaining plumpness and hydration. We lose natural hyaluronic acid with age, which can lead to dehydrated skin, fine lines and wrinkles. Topping up your levels of HA with a daily hydrating serum is a smart move, especially for more mature skin. Larger hyaluronic acid molecules also create a water-tight barrier effect which helps to maintain all-day hydration and protect against environmental stressors.

Our top picks for hyaluronic acid serums

1. Skingredients Skin Veg Pre-Seum

This lightweight serum contains hydrolysed hyaluronic acid, pro-collagen peptides and botanical extracts to soothe and nourish the skin from the first use. Low molecular weight hyaluronic acid penetrates deeply into the epidermis where it can revitalise tired skin.

Retinol

You may know that retinol is the go-to ingredient in anti-ageing skincare, but it has a wide range of benefits for all skin types.

Other Antioxidants

Antioxidant serums have become essential in any skincare routine, praised for their ability to protect and rejuvenate the skin.
