Pigmentation Treatment
Pigmentation is a broad skincare condition, which generally refers to light or dark irregular patches on the skin – this can occur in smaller patches or larger patches due to excessive melanin production that disperses unevenly. Pigmentation is an umbrella term that covers hyperpigmentation, melasma and age spots.
有什么症状？
Many forms of hyperpigmentation are caused by an excess production of melanin. Melanin is produced by melanocytes at the lower layer of the epidermis. Melanin is a class of pigment responsible for producing colour in the body in places such as the eyes, skin, and hair. As the body ages, melanocyte distribution becomes less diffused and its regulation less controlled by the body. UV light stimulates melanocyte activity, and where concentrations of the cells are denser than surrounding areas, hyper – pigmentation forms.
Melasma is a common skin condition which causes dark, discoloured patches on your skin. It’s also called chloasma, or the “mask of pregnancy,” when it occurs in pregnant women. Melasma causes patches of discoloration. The patches are darker than your usual skin colour. It typically occurs on the face and is symmetrical, with matching marks on both sides of the face. Other areas of your body that are often exposed to sun can also develop melasma. Brownish coloured patches usually appear on the: cheeks, forehead, bridge of the nose and chin. It can also occur on the neck and forearms. The skin discoloration doesn’t do any physical harm, but you may feel self-conscious about the way it looks. A visual exam of the affected area is often enough to diagnose melasma. To rule out specific causes, your practitioner might also perform some tests for the diagnosis.
Age spots are usually slightly larger than freckles but smaller than other patches of pigmentation and occur more often in those with fairer skin types. They’re also called liver spots, senile lentigo, solar lentigines, or sunspots. Despite their name, they’re not caused by ageing, but through continual sun exposure and sun damage.
它会影响谁
Hyperpigmentation has prevalence among those with Asian, Mediterranean, Latin and African heritage and darker skin tones. It’s also often seen on those who have spent excessive time in the sun, and have had prolonged UV exposure. As this damage accumulates over time, the pigmentation usually darkens or becomes more noticeable with age.
原因
Hyperpigmentation may be caused by sun damage, inflammation, hormone, or other skin injuries, including those related to acne that induce excessive melanin production. People with darker Asian, Mediterranean or African skin tones are also more prone to hyper – pigmentation, especially if they have excess sun exposure. When the production of melanin is excessive, the pigment can spread unevenly, creating brown patches and splotches. It isn’t totally clear what causes melasma. Darker-skinned individuals are more at risk than those with fair skin. Estrogen and progesterone sensitivity are also associated with the condition. This means birth control pills, pregnancy, and hormone therapy can all trigger melasma. Stress and thyroid disease are also thought to be causes of melasma. Additionally, sun exposure can cause melasma because ultraviolet rays affect the cells
Age spots may affect people of all skin types, but they’re more common in adults with light skin. Unlike freckles, which are common in children and fade with no sun exposure, age spots don’t fade. Age spots are flat, oval areas of increased pigmentation and are usually tan to dark brown. They occur on skin that has had the most sun exposure over the years, such as the backs of hands, tops of feet, face, shoulders and upper back and range from freckle size to about 1/2 inch (13 millimeters). They can group together, making them more noticeable.
Diagnosis
One testing technique is a woods lamp examination. This is a special kind of light that’s held up to your skin. It allows your healthcare professional to check for bacterial and fungal infections and determine how many layers of skin the melasma affects.

Expert Tip
Your Practitioner will advise you on skincare products that can help lighten your pigmentation which will further enhance and boost your treatment. These may be prescription strength skin lightening agents such as Tretinoin or Hydroquinone. Preventative and protective measures can help to ensure your pigmentation does not get any worse. You should always use SPF 50 or higher daily, reapplying every few hours, even on a cloudy day.
治疗方案
Some forms of pigmentation like melasma can be particularly tricky to address and treat. Fortunately, with years of experience, our expert practitioners combine the latest advancements in skin-tone-improving treatments with the use of brightening active ingredients to create a unique pigmentation programme. Our approach to treatment aims to ensure that we’ll not only treat the condition but also provide you with proactive steps to prevent the pigmentation from returning.
We also offer Obagi and Cosmelan topical skincare systems to correct hyperpigmentation and even skin tone. The Cosmelan programme contains an at-home preparation kit, followed by an in-clinic skin peel, while the Obagi system contains a range of skincare products to improve your skin tone over time. It’s a prescription-only programme, and your practitioner will help you determine the best course of treatment to improve your pigmentation, melasma or dark spots. During your consultation, we may use our advanced skin scanner to assess the quality of your skin and its conditions to tailor your treatment programme accordingly.
Etherea IPL
Through creating micro-thermal injuries, the IPL treatment resurfaces and renews the skin to lighten darker areas. Not everyone is suitable for this laser treatment, and it can depend on your skin type.
治疗涉及什么？
您的咨询将决定您是否适合接受治疗。
The nurse will apply a numbing cream to minimise discomfort during treatment. We will configure the depth depending on the area and concern, and the device will make a few passes over your skin, delivering bursts of energy.After the IPLtreatment, you may notice square formations with tiny pinprick dots on the skin. The nurse will apply a topical serum to minimise these marks.
治疗需要多长时间？
IPL uses light energy to target a certain colour in your skin. When the skin is heated, your body gets rid of the unwanted cells, and that gets rid of the thing you’re being treated for. Unlike lasers, an IPL device sends out more than one wavelength of pulsating light.
需要多少次治疗？
Most patients require 4-8 sessions. One session every 4-6 weeks depending on the severity of the skin concern.
治疗需要多长时间？
Numbing cream is applied for 20 minutes, followed by the treatment, which takes approximately 30 minutes.
Laser Treatment
We use a Clear and Brilliant non ablative fractional laser to target melanin to effectively treat an array of pigmented lesions like sunspots and age spots. It’s not suitable for all skin types, so your practitioner will establish whether this is the best treatment for you.

皮肤脱皮
Ranging in varying strengths and chemicals, a skin peel can minimise the appearance of dark patches by sloughing off dead skin cells and resurfacing the skin. Cosmelan is a particularly effective pigmentation programme that we offer.
治疗涉及什么？
治疗从咨询开始，您的医生将评估您的皮肤以破译您的皮肤状况和最佳治疗方案。
Certain peels like Cosmelan or Dermamelan may require skin preparation with the use of at-home products in the lead up to your appointment. Your practitioner will prescribe a list of recommended products that will be suitable for you or provide you with the appropriate preparation kit.
如果我们用 Cosmelan 果皮为您治疗，我们将要求您在初次治疗前使用脱色准备套装，让您的皮肤为果皮做准备。
在您的治疗期间，您的医生将通过在敏感区域周围涂抹隔离霜来双重清洁和准备皮肤，并去除所有皮脂以帮助酸渗透。
在此之后，我们将应用选择的果皮并在中和或去除果皮之前将其放置几分钟。中和剂会阻止酸在皮肤上起作用，而去除湿巾会使酸在皮肤上保持活性，从而在治疗后继续改善肤色。

Dermapen & PRP
At Harley Street Injectables we often combine both Dermapen and PRP together to treat pigmentation due to their healing properties and ability to improve a multitude of pigmentation issues in all skin types by improving overall skin tone and texture. Dermapen uses a small hand-held device with varying needle depths ranging from 0.5mm and 3mm that create a minor trauma to the dermal layers. The process breaks down stubborn pigmentation and triggers the formation of new collagen, making it suitable for many types of acne scarring. Additionally, platelet-rich plasma therapy improves the appearance of pigmentation by re-training the patient’s platelet-rich fibrin matrix. When your Practitioner re-injects the platelet-rich plasma, back into the skin, it encourages wound healing and promotes the growth of new collagen.
治疗涉及什么？
The Dermapen treatment usually begins with the application of a topical numbing cream. Using a hand-held pen-like device, the Practitioner will then make several passes over the entire face.
治疗效果如何？
The collagen inducing Dermapen creates virtually invisible micro-injuries in the skin that ignite the body’s healing and regenerative processes. This influx of collagen, elastin and release of growth factors results in an overall improvement in the skin’s smoothness, suppleness, and strength.
Additionally, the micro-channels allow for optimal absorption of active ingredients to enhance their results and increase their efficacy.
有没有停机时间？
Immediately after the treatment, you may notice tiny pinpricks of blood. The Practitioner will usually pat the face down after which point; the skin will no longer draw blood.
Your skin may be red for up to 24 hours and will gradually resolve throughout the following week. It may also feel a little rough, warm and dry for the first couple of days after your treatment and may begin to flake.
需要多少次治疗？
We recommend 6 treatment sessions. Every four weeks.
Cyropen
Cryopen is an ideal solution for the removal of skin lesions and imperfections such as; Skin Tags, Milia, Cherry Angiomas, Age Spots, Warts and Verrucas in a fast, painless fashion. Flawless skin can be chieved in seconds with minimal invasion and without the need for injections. Cosmetic procedures such as skin tags, millia and cherry angiomas are no longer treatable as a standard NHS procedure, however the need for it is still necessary. Cryopen is a quick and easy solution to these common skin conditions without the need for anaesthesia or injections. Cryopen is virtually pain free and without the need for injections, it’s even suitable for children. Anyone who suffers with skin imperfections can be considered as a candidate for this procedure, however it is good practice to always discuss with a trained professional prior to the treatment.
What happens during the procedure?
Performed with a tiny applicator, it is held to the skin imperfection and then liquid nitrogen is sprayed onto the unhealthy tissue. Dependant on the size of the tissue, it can take between 1-30 seconds. The skin is then allowed to thaw, and return to its natural colour. The process can be repeated on the same area, depending on the severity.
有没有什么副作用？
This procedure is non-invasive and considered low risk. The risk of side effects are very rare but a few that could be noticed are:
Temporary pigmentary changes in the treatment site.
Temporary loss of sensation
Blister in the treatment area
How long does it take to heal?
The procedure isn’t painful and the process of healing following is no different. It usually takes 1-6 weeks depending on the size of the treatment area. Lesions usually assume a darker colour as the skin regenerates underneath it will slough or flake away.
