Fine lines and Wrinkles
Ageing skin droops and develops wrinkles, lines and furrows. The severity of these changes in an individual depends on the genetic tendency, skin type and exposure to environmental factors. Wrinkles occur when the skin loses suppleness and tightness as it ages. It is seen more commonly in areas of skin which are stretched regularly such as around the eyes (crow’s feet), forehead and mouth. By renewing the production of collagen the skin becomes plumped out, thicker and retains its elasticity.
Acne scarring
A significant proportion of acne sufferers will have some form of scarring to show for it. Medical studies suggest that between 30% and 95% of patients with acne develop some form of scarring.
Importantly, seeking early treatment for acne helps to reduce the risk and severity of acne scarring. Microneedling mechanically breakdowns existing scarring and stimulates the production of collagen and elastin, vital components of healthy skin. This has the effect of smoothing out the skin due to the reduction of the size and depth of acne scars. Clients usually have an immediate glow to the skin, but the visible changes develop over a course of several days and weeks. Results can continue to improve for up to 6 months after the treatment as collagen production continues. Not all acne scars are well suited to treated by microneedling. In particular, microneedling is not well suited to treat keloid scars as there is mixed evidence of its effectiveness. Keloid scars are formed when scar tissue forms on the skin in excess, because of excess collagen production. Individuals with keloids scars should consider alternative treatments such as the use of steroids.
Stretch marks
Stretch marks are caused by prolonged skin distension due to pregnancy and weight gain. It can also be caused by prolonged use of oral and topical corticosteroids which hinder the formation of collagen and elastin fibres. There is no effective treatment to correct stretch marks as the epidermis in stretch marks is weakened and the support structure beneath it is compromised. Microneedling will improve the density of the epidermis by stimulating the epidermal growth factor but it is important not to overpromise results.
Rosacea
Rosacea is most commonly seen after age 30, and may initially resemble a simple sunburn or a mysterious redness. Early treatment is key. Rosacea cannot be cured but it can be controlled. Microneedling can help control rosacea by stimulating the epidermal growth factor which increases the density of the epidermis. This lessens the appearance of vessels beneath the skin and the overall redness. It strengths collagen in both vessel walls and connective tissue that supports the vessels. It also increases the availability of cell nutrients and antioxidants.
Hair loss
Hair loss can be caused due to a variety of factors such as genetics, iron deficiency, infections (bacterial, fungal and parasitic) and hypothyroidism. Microneedling can help correct hair loss by increasing the availability of cell nutrients and stimulating blood flow in the scalp. It releases vascular endothelial growth factor which promotes hair growth and increases hair follicle size. Microneedling is primarily used in combination with topical products such as Minoxidil.
Pigmentation
Pigmentation occurs in two different forms — passive and inflammatory. Inflammatory pigmentation occurs as a result of the activation of our skin’s natural defence mechanisms. Melanin moves up to defend against trauma caused by factors such as sun exposure, poor products or injury. Passive pigmentation results from an internal imbalance which stimulates the melanin stimulating hormone.
These imbalances can be caused bby pregnancy, hormonal imbalances, the contraceptive pill and various medications. Microneedling can correct pigmentation by increasing the availability of skin lightening actives. It also normalizes the cell signalling function which when overstimulated, causes overproduction of pigment.
