It is one of the downsides of the technological age...the premature wrinkling around the neck suffered by those who constantly look down at their smartphones and tablets.
But beauty experts have come up with the answer to combat the sagging skin and creases of so-called 'Tech Neck' – a £65 cream.
YSL Beaute has created two products that use a special molecule to combat the loss of elasticity in the skin around the body's Y-Zone – the lower face, throat and decolletage.
It claims its Forever Youth Liberator Y.Shape cream impregnates the skin with millions of micro-droplets, creating a cushion that smooths and plumps the skin. Tech Neck wrinkles are most often found in those aged 18 to 39 who have an average of three digital devices and peer at their screens up to 150 times a day, say experts.
公司称他们的年轻妍活修复系列Y型霜（Forever Youth Liberator Y.Shape cream）向皮肤输送了数以百万计的微小液滴，形成可以使皮肤光滑丰满的保护层。
But this speeds up the loss of elasticity that would normally occur at middle age, while a constant downward gaze adds further lines and creases around the chin and neck.
Meanwhile, the company's Y.shape 'concentrate' product apparently restores the skin's elasticity to lift the area, re-plump the skin and boost lost volume.
YSL claims one single application of the £65 product increases skin elasticity by nearly a third and skin firmness by 13 per cent.
Dr Christopher Rowland Payne, consultant dermatologist at The London Clinic, said 'The problem of wrinkles and sagging of the jowls and neck used to begin in late middle age.
伦敦诊所的皮肤科顾问医生克里斯多夫·罗兰·佩恩（Christopher Rowland Payne）博士表示，“面颊和颈部皮肤松弛和出现皱纹的现象通常在中老年时期出现。”
'But in the last ten years, because of 'Tech Neck', it has become a problem for a generation of younger women.
'Neck skin is exposed to sun every day because of low necklines, especially in women, but people are less inclined to think of protecting their necks than their faces.
'If they do, they often apply insufficient cream on their necks to avoid getting it on their clothes.'
