What causes loose neck skin?

Loose neck skin can be attributed to several age-related and lifestyle factors:

• As skin matures, collagen and elastin production gradually declines. Since these two proteins are what give skin its firmness, volume, and elasticity, this natural depletion causes sagging skin under the chin.

• Genetics play a role in the elasticity and structural integrity of skin.

• Prolonged UV damage can accelerate visible signs of ageing and break down collagen and elastin in the skin.

• Frequent weight fluctuations can cause skin to lose some of its natural stretch and bounce – especially around the thinner skin of the neck.

• Poor lifestyle habits such as smoking, excessive alcohol consumption, lack of nutrition, and even poor posture can all contribute to sagging around the neck.

How can you tighten neck skin?

Alongside preventative, healthy lifestyle habits, you can tackle loose neck skin using active ingredients that support hydration and collagen production.

Read on for our five expert tips to tighten neck skin.

1. Introduce collagen-boosting skincare

Collagen can’t be applied topically (which is why people have it injected), so you’ll need to apply skincare ingredients that stimulate collagen synthesis in the body.

Below are three of the most powerful, collagen-boosting ingredients.

· Retinol: This vitamin A derivative encourages collagen production and skin cell turnover. This helps smooth the appearance of fine lines and wrinkles, while improving skin elasticity.

· Peptides: Short-chain amino acids that act as messengers, signalling the skin to repair itself and produce collagen.

· Vitamin C: Alongside its collagen-stimulating benefits, vitamin C also neutralises free radicals that cause oxidative stress – a process that can accelerate visible ageing concerns like loose neck skin.

2. Hydrate and plump the skin

The appearance of wrinkles and sagging skin becomes more noticeable when the skin is dehydrated. So, alongside your collagen-stimulating skincare, it’s important to keep the skin plump and hydrated.

Humectants, such as hyaluronic acid and glycerin, extract water from external sources and bind it to the skin surface, which helps boost your skin’s overall moisture retention.

Harnessing glycerin and four forms of hyaluronic acid, the Hyalu B5 Suractivated Hyaluronic Acid Serum targets visible fine lines, wrinkles, and loss of firmness and volume. Be sure to disperse this serum all the way down to the décolletage to help with neck firming.

3. Don't neglect your SPF

Neck tightening is as much about prevention as a targeted skincare approach.

UV damage is one of the major contributing factors to visible ageing concerns – including loose neck skin – but ensuring your skin is well-protected against UVA and UVB rays can help prevent sagging skin under your chin. 

Our Anthelios broad-spectrum sunscreens are all created for sensitive skin, but you can choose a sunscreen for your skin type to ensure optimal comfort on the face and neck. 

4. Use a gua sha on the neck and décolletage

Facial sculpting tools – like a gua sha – can be helpful for sagging skin under the chin. Traditionally made from crystal, a gua sha is used to improve circulation, perform lymphatic drainage, and tone the appearance of loose skin around the neck.

To ensure the tool glides effortlessly across skin without stretching or tugging, a gua sha is most effective on freshly moisturised skin. For this, we recommend the Hyalu B5 Suractivated Cream for the face and neck – an advanced anti-wrinkle cream that combines four forms of hyaluronic acid to help plump and firm skin.

5. Practise healthy lifestyle habits

Alongside SPF and a supportive skincare practice, you can help prevent loose neck skin with the following lifestyle tips:

• Avoid smoking and vaping – both habits can impact your skin’s natural elasticity.

• Be conscious of your posture and ‘text neck’ – these repetitive straining motions can contribute to neck wrinkles.

• Reduce alcohol consumption – as a diuretic, alcohol can dehydrate the skin and make wrinkles appear more pronounced.

• Maintain a stable weight – rapid weight fluctuations can stretch out the skin and cause changes in skin elasticity.

In addition to tightening neck skin, skincare can also assist with other age-related textural concerns. Next, find out how to manage marionette lines with a targeted skincare approach.
