What causes skin to age?
Reduced collagen – there is a drop in collagen production each year from around the age of 25, causing skin to become thinner and more fragile as we get older.
Elastin production also plays a part in keeping skin taut and that also decreases with age.
Sebaceous glands produce less sebum over time, leading to dryness, itchiness, and a slightly textured appearance.
Excessive sun exposure – UVA and UVB radiation is a key factor. UVA radiation affects the deeper layer of skin, breaking down collagen and elastin fibres. UVB affects the outer layer of the skin and can damage the DNA structure.
Pollution contributes to the ageing process as free radicals in the atmosphere can react with the skin’s surface.
Poor diet with large amounts of fatty foods lacking in key nutrients can leave the skin looking dull and dry.
Smoking can cause deeper wrinkles on the face due to the damaging impact of tobacco smoke on collagen and elastin fibres.
Supporting healthy skin ageing
While we can’t prevent ageing, there are some lifestyle habits that can support a healthy complexion:
Good sun habits – Choose a daily moisturiser with a high SPF (30+) to wear all year round.
Exercise regularly - cardio activity can increase blood flow and help to nourish skin cells.
A good night’s sleep –the skin’s blood flow increases while we sleep, allowing your skin to repair from the day’s damage. Sleep also helps to promote collagen production.
Maintain a healthy diet - Antioxidant-rich foods such as fruit and vegetables can help reduce the negative impact of free radicals on our skin.
Vitamin C – Consider using products with vitamin C as some evidence suggests it may help to reduce skin dryness and the appearance of wrinkles.
Use a retinoid – Retinol is found in many skincare products. It’s known for regenerating blood vessels within the skin and increasing the production of collagen. It has become increasingly popular in recent years for helping to reduce the appearance of fine lines and wrinkles. Always follow the guidance on the product when using retinol products as it is key to ease it gently into your skincare routine if you are using it for the first time.
Good all-around skincare routine – Use the most appropriate products for your skin type in your daily routine to keep your skin cleansed and well-hydrated.
