DHK Defence Serum
DHK Defence is the serum MARGIN, a British Columbia skincare brand, built to sit between cleanser and moisturizer as a daily layer. The brand focuses it on the skin barrier and on everyday city and weather exposure. It is a considered, science-led formula for someone who already has a routine and wants one more step that earns its place.
A breakthrough defence against environmental stressors and barrier damage that accelerate skin aging. DHK Defence repairs, protects and reinforces the skin barrier.
With daily use, skin appears brighter, firmer and more youthful.
Every product here is shipped directly by the brand that makes it, so shipping rates and delivery times are set by each brand. If your order includes products from more than one brand, it may arrive in more than one parcel.
Returns and exchanges are handled by the brand too, under its own policy. Questions about an order? Get in touch and we will point you to the right place.
