The make-up quick fix
1. BLUE UNDERTONES are the pigment of oxygenated blood showing through thin skin. It gathers during sleep, which is why blue or purple circles can be more prominent in the morning. Cover them up with a yellow- or pink-toned colour corrector, such as Dior Fix It Colour in Yellow, £23.50, or Giorgio Armani Master Corrector in Rose, £26.
2. BROWN UNDERTONES are the result of decreased proteins and lipids, which are related to your genes, excessive sun exposure or behavioural factors. Cover them up with a peach-toned colour corrector, such as Urban Decay Naked Skin Colour Correcting Fluid in Peach (for fairer skin tones) or Deep Peach (for darker skin tones), £19 each.
