In the same way that most Tube maintenance is carried out at night, it’s while we’re asleep that skin does most of its essential repair and rejuvenation work, providing the perfect opportunity for you to give things a helping hand with a raft of night-time skincare products increasingly popular with men.

As well as being the best time to apply spot creams (most suggest you apply overnight rather than during the day), it’s also a good time to use a hydrating moisturiser, since trans-epidermal water loss (i.e. water lost from your skin via its epidermis) is greater at night.

What’s more, DNA and collagen synthesis occurs at night, cellular repair is heightened, and skin is more receptive to concentrated reparative skincare treatments. Which explains why many skin ‘repair’ products are designed for night-time rather than daytime use.

Getting some quality kip is crucial, too, of course (research by Duke-NUS Graduate Medical School in Singapore showed that six to eight hours a night is optimum) and if you don’t get enough, your skin, as the body’s largest organ, is sure to let everyone know.

The perfect, skin-saving bedtime routine needn’t be complicated or time-consuming either. Apart from washing away the daily grease and grime with a decent cleanser it can be as simple as slapping on a specially formulated night cream (keep it on your bedside cabinet so you don’t forget to apply it) or as complicated as applying hydrating masks, serums, eye creams and overnight exfoliants like Origins’ Night-A-Mins Oil-Free Resurfacing Cream.

Sadly, men have traditionally been resistant to the use of bedtime lotions and potions – possibly viewing them as unnecessary or an inconvenience – but if you’re a guy who cares about how his skin looks during the day you should definitely be looking after it at night too. Still not convinced? No worries – why don’t you just sleep on it?
