A milky serum for skin that turns red, tight and itchy at the slightest thing
A-Derma Exomega Ultra-calming serum 30ml (1.01fl oz) is a 30 ml daily soothing serum for reactive skin, built to calm on contact and make the skin less quick to react over time. Its actives are Rhealba® Oat, Cutalgine and natural helichrysum, in a formula that is 99% of natural origin. The texture is a light, cool milk that sinks in fast with no greasy or sticky film, so it layers under whatever cream you already use. A-Derma built its whole range around Rhealba® oat, an extract you will not find in American sensitive-skin lines.
Targeted actives with proven results
The formula goes after skin hyper-reactivity with highly tolerated natural actives. Rhealba® Oat helps restore the skin's 3 key proteins, while Cutalgine soothes discomfort and reinforces the skin barrier, and helichrysum - an approach inspired by targeted therapies - helps reduce excessive reactions. The brand's testing reports an immediate ultra-calming effect, skin strengthened in 3 days and redness down 72%1, in a formula that is 99% naturally derived.
Optimal texture and tolerance
The fresh, milky texture absorbs quickly and leaves nothing greasy or tacky behind, which is what makes it a good base layer before the rest of your routine. It is formulated for very sensitive skin, with the ingredient list kept short to minimise the risk of a reaction. In daily use that means comfort first: it is a serum you can apply once or twice a day on skin that feels tight without adding weight to the routine. 1Usage test under dermatological control.
Who it suits
- Reactive skin with atopic tendencies, prone to redness and itching
- Once or twice a day, on clean skin, before your usual moisturiser
- Winter, hard water and central heating, when skin gets tight
- Anyone who wants a soothing step that is not another thick cream
Worth knowing before you buy: this is a serum, not an emollient - on very dry or atopic skin you still need a rich cream on top, so it is an addition to a routine rather than a replacement. The figures quoted come from a usage test under dermatological control, not a large clinical trial, and it should be kept away from the eye contour. It is skincare, not a treatment for a flare-up: see a doctor for that.
