Barrier Support Serum


With 5% niacinamide, ceramide complex & hyaluronic acid

If your goal is healthy skin then you need to keep your skin barrier in check. The skin barrier is the first line of defence against environmental assaults and unwanted substances so it’s vital to keep it fully functioning and maintain its resilience. A compromised barrier can result in dry, dull, irritated skin and the potential for sensitivity as unwanted substances are more easily able to penetrate the skin.

This clear, hydrating serum is designed to support, protect and replenish the skin barrier, allowing it to maintain its optimal hydration balance and keep skin healthy. Silicone, oil and alcohol free, with a weightless gel texture, this layers perfectly under a moisturiser.

How to use:

Dispense less than half a pump of serum into the palm of your hand and apply to damp clean skin. Immediately follow with a moisturiser (+ oil if needed) to seal in moisture. Can be used morning & night, and under the eye area. In the daytime, complete your routine with a broad-spectrum sunscreen to protect your skin.

TIP: If you haven’t used niacinamide before, introduce gradually (once every other day) and build up slowly to once or twice daily use. As with all products, patch test first and discontinue use if irritation occurs.

You may notice the serum turns a little white as you apply it – this is perfectly normal (it immediately disappears) and is just the serum emulsifying with the natural oils on your skin surface.

Store in a cool, dry place out of direct sunlight. For external use only. Keep out of reach of children. Shelf life unopened is 30 months. Once opened use within 12 months.
