There are many factors that can trigger your pigmentation. These can include a rubbing habit, chin plucking, and exposure to computer screens. Learning your triggers will help you manage your pigmentation. Pigmentation results from overproduction of an enzyme called tyrosinase. This enzyme converts the amino acid Tyrosine to oxidize and produce pigment. Pigmentation treatments are used to treat various skin conditions including acne scars, sun damage and age spots.

Millisecond pulse width lasers
Currently, there are several advantages to using Millisecond pulse width lasers for pigment treatment. These devices are capable of providing a more accurate treatment. They can target different parts of the skin and minimize photoreceptor damage. Furthermore, these lasers can be adjusted to provide a specific dosage.
In the first study, alexandrite lasers with a wavelength of 755 nm were evaluated for their ability to treat pigmentation lesions. This particular wavelength possesses a low risk of adverse events, which is ideal for treating pigmented lesions. In addition, the alexandrite laser can treat darker skin types, and its variable pulse width allowed for higher fluences.
However, this method has a few drawbacks. The lasers’ wavelengths must be chosen carefully, because melanin is absorbed much more efficiently than haemoglobin. For this reason, longer wavelengths require higher fluence to do the same damage. In addition, a patient’s skin’s melanin content should be analyzed to determine the right wavelength for the treatment.
Hydroquinone
Hydroquinone is a topical solution used for the treatment of hyperpigmentation in the skin. While this treatment is safe, there are some side effects associated with its use, such as allergic contact dermatitis. It should be used under the supervision of a medical professional and should not be used in larger doses than prescribed by your physician. Hydroquinone is also known to cause skin irritation, so it is important to follow the doctor’s instructions when using this product.
Hydroquinone can be used for hyperpigmentation and freckles, which are skin conditions caused by overexposure to sunlight. It works by preventing the growth of melanocytes and reducing their production. The result is a lighter skin tone. The results are visible in about 4 weeks or three months. However, it is important to follow the manufacturer’s instructions and avoid sun exposure during the treatment period. Melasma is a very common skin condition that affects many people. It usually appears as brown or red spots on the face.
Topical lightening agents
A number of different topical lightening agents are available, from creams to serums. While they do not remove pigmentation in all cases, they can help improve the appearance of skin and help patients avoid the need for laser treatment. Topical lighteners can also be used to prepare skin before laser treatment, which can reduce post-inflammatory hyperpigmentation. However, these agents should only be used on specific skin areas.
Topical lightening agents may involve different plant extracts, depending on the level of pigmentation. For instance, hydroquinone is an agent that is used in creams and lotions to treat hyperpigmentation. However, its bleaching effect is reversible in sunlight and requires regular application. These agents can also be found in emulsions, gels, and lotions. These agents work by inhibiting the enzymatic conversion of tyrosine to DOPA, which reduces the pigment in the skin. They also reduce the melanocytes’ ability to transfer melanin.
Solar lentigos
There are a number of treatments for solar lentigos. These treatments can include chemical peels, laser therapy, and intense pulsed light. However, some treatments are not suitable for people with darker skin. The first step in solar lentigos treatment is a dermatologist’s diagnosis. A dermatologist can determine whether the lesions are caused by solar radiation or a melanoma by looking at their appearance.
The lesions in solar lentigos have melanosome complexes, which are found in the basal keratinocytes of the epidermis. They are composed of poly-melanosomes with mammoth-shaped envelops that are located above the nucleus of the cell. They are also associated with elevated expression of growth factors, which influence melanocyte genetic expression in photo-traumatic cutaneous zones. In addition, solar lentigos have a lack of pigmentation genes, as well as genes associated with inflammatory response, Wnt family genes, and metalloproteases.
