UV exposure in particular is harmful to the skin, breaking down collagen and elastin, which keep skin supple and firm. UV rays can be encountered not just when directly in the sun, but also on tanning beds, speeding up the natural ageing process.

Smoking, thanks to the effects it has on the supply of oxygenated blood to the upper layers of skin, accelerates skin’s ageing process, and lack of vitamin A in your diet can affect cell turnover, leading to less healthy skin that is more prone to damage as it is dehydrated.

Changes in weight can alter the appearance of your skin; as you gain weight your skin stretches, and during fast weight loss, it isn’t given the time to adjust and shrink, leaving it saggy or loose, especially in areas that are delicate like the neck and décolletage.
