If you thought your hands show your age, take a look at your neck.

That old ‘gobble gobble’ excess of skin is one of the hardest to fix, as it's an area we exercise the least.

Turkey neck is caused by flaccid muscles, loose skin and fat. The neck is not the easiest of areas to treat but if you follow our tips, you’ll turn your neck from turkey back to spring chicken in no time.

1. Stretch it

Stretching your neck on a day-to-day basis can train the skin to be taut rather than loose. Try to sit up straight when on a computer or laptop, holding your head up high.

Sleeping can help tighten it too if you try to sleep with your neck long – ditch two pillows and stick with one to reduce the angle between the face and the neck.

2. Flex your muscles

You can exercise your neck with these two facial yoga moves.

Firstly, smile in six stages. Make sure you engage your neck, keeping the mouth closed.

Secondly, sit back on a chair with your back straight and slowly lean your head back until you’re staring at the ceiling. Pout your lips as though you are kissing the ceiling and hold the pose for a few seconds. Repeat 10 times. 

3. Roll with it

Facial rollers (like the Jade Facial Roller or Sarah Chapman Skinesis The Facialift) are a quick and efficient way to tone up your face and neck. Like a mini paint roller, they are designed to aid lymph drainage and blood flow, eliminating puffiness, kick-starting facial muscles and plumping out wrinkles. Roll ‘up’ your neck once a day for best results.

4. Tighten and tone

Duleesha, facialist and Aesthetic specialist at Hiro Miyoshi Hair & Beauty salon in Mayfair, suggests: "The best treatment in preventing sagging skin on the neck would be a course of Radio Frequency skin tightening facials.

"I would recommend this treatment once a week  for 6-8 weeks, and a maintenance every 6 weeks. RF skin tightening is used for firming and removing the appearance of sagging skin around face, neck and body.

"This works by applying a gentle heat in the deep, collagen rich layers of your skin. The heat helps tighten existing collagen and stimulate the formation of new collagen over time, which reduces sagging, renews contours, and improves the smoothness and texture of the skin's surface."

5. Apply aptly

Your neck contains fewer oil glands than the face, so the skin can get dry and wrinkle easily. Just as you apply serum and moisturiser to your face, you should give your neck the same love.

Take your cleanse-and-tone routine to your neck and finish with a sweep of a cream using upwards motions to boost circulation.

Lulu's Time Bomb Troubleshooter Neck & Jaw Cream does what it says on the tin - it deeply hydrates a dry, mature neck; if it’s a rich, luxurious cream you prefer, Clarins' Extra Firming Neck Cream is just that and more.
