The Serum
What it does
A daily brightening and firming serum formulated for skin shaved four to seven times a week. Targets the marks that linger on the jaw and neck after a shave. pH 6.5, so no sting on a fresh shave.

How to use
Morning, after cleansing, on dry skin. Three to four drops over the face, jaw and neck. Follow with moisturiser and SPF. Not for use in the same routine as a copper peptide product.
Texture and scent
Clear, water-light, absorbs in under a minute. Fragrance free. No colourant.
Allergen
Contains hydrolysed lupine protein, a legume. Not suitable for anyone with a lupin or peanut allergy.
SiriusDefence™
A peptide complex built around Matrixyl Synthe’6 with hydrolysed lupine protein. Supports the look of firmness on skin stressed by the daily shave.
SiriusBarrier™
A barrier complex formulated for the daily stress of razor, weather and city. The reason the serum feels calm on a freshly shaved jaw.
Close to skin’s own
Most strong vitamin C serums use L-ascorbic acid, which needs a pH near 3 to work. On skin shaved four to seven times a week that is a formula that stings and a barrier already under strain.
The Serum uses sodium ascorbyl phosphate. Stable in the bottle, effective at pH 6.5, it does not oxidise orange. It was chosen because of how men actually use it.
