Skin Density

'Skin density' refers to the thickness of the skin, and it differs from one area of the body to another. Unfortunately, our skin gets thinner with age, which is why older people can seem to have 'paper thin skin.'

The Structure of the Skin

The skin has three layers:

  • The epidermis, which forms the skin's physical and biological barrier. This helps to keep out irritants and allergens, while preventing the loss of moisture.
  • The dermis, which cushions and protects deeper structures, nourishes the epidermis, and is important in wound healing.
  • The hypodermis, which lies below the dermis. It mainly consists of fat, insulating the body, and also structurally supports the skin.

How Skin Density Varies Across the Body

The skin on our face is much thinner than the skin on the rest of the body. Even on the face itself, some areas have thinner skin than others, particularly the eyes and lips. There are no oil glands around the eyes of lips, which is why wrinkles tend to appear around the eyes first and why lips can so easily become dry cracked.

The skin is also very thin on the neck and chest area, which is why this area can be especially prone to wrinkles and loose skin.

The Factors That Affect Our Skin

Genetics and Aging

Thin skin can be hereditary, and our skin thins naturally as we age. After the age of 20 we lose about one per cent of collagen, the skin's scaffolding protein, every year. The more collagen we lose, the thinner our skin appears.

Pollutants and UV Light Damage

Pollutants, such as smoking, and UV light from the sun ortanning beds can break down collagen and elastin, the proteins that give our skin its plumpness, firmness and elasticity.

This is why our hands, which are often exposed to sunshine as well as moisture-stripping cleansers, can be prone to wrinkling, making the skin here look older than the skin on the rest of the body.

Menopause and Medications

Menopause, with its drop in hormone levels, can reduce moisture and collagen production in the skin, making it thinner and prone to sagging. There are also medications that can thin our skin by affecting fluid levels. Long-term steroid use in well-known to thin the skin, particularly if it's applied topically (directly on to the skin, e.g., in a cream or ointment).

Medical Conditions

Certain medical conditions can cause thin skin. For instance, Ehlers-Danlos Syndromes (EDS) affect the connective tissues of the body, and can result in thin, fragile and stretchy skin.

Can Microneedling Help Skin Density?

Preserving collagen in the skin, and stimulating it, can help to make the skin look plumper, firmer and younger.

Microneedling involves running fine needles (around 0.5mm –1mm long) over the face, creating tiny punctures on the skin's surface. The skin reacts by forming new collagen to heal these small wounds, and the needling process also stimulates elastin production, resulting in a new, smoother, skin layer.

Microneedling treatments are usually a month or six weeks apart, and several treatments are normally needed to see significant results.

Microneedling Aftercare

After a microneedling session, your skin may become inflamed or a little bruised, but this quickly fades, lasting a few days at most. Drinking plenty of water in the days leading up to the microneedling session can help to reduce bruising and inflammation. You should avoid direct sunlight and strenuous exercise for a short period afterwards to give the skin time to heal.

Want Younger, Firmer Skin?

Microneedling is a safe and effective way to boost the natural proteins in the skin, giving it a firmer texture and a younger look. However, it's not suitable for everyone.

You should avoid microneedling treatment:

  • On areas of keloid (raised or 'bubbly') scarring
  • If you are pregnant or immunosuppressed
  • If you suffer from eczema or psoriasis
  • If you take anticoagulants (blood-thinning medications)

If you have rosacea, seek professional advice first. The suitability of microneedling for your condition may depend on the type of rosacea you have and what triggers it.

If microneedling is suitable to you, then it's a great way to get younger, firmer skin. You can look forward to seeing a new, smoother and more resilient skin layer appearing within a few treatments.
