Treatment options for different pigmentation

How to choose the right laser treatment to solve skin pigmentation problems? Modern people lead very busy lives and feel tired if they do not get proper rest. Besides, weather changes, air pollution and lifestyle issues are all factors that aggravate skin aging, so there are countless people suffering from various skin conditions such as sagging skin, fine lines and wrinkles, pigmentation, melasma, etc.

Explanation of pigmentation

Hyperpigmentation is a skin condition caused by excessive melanin production in the body. Other factors such as continued exposure to UV rays, pollution, endocrine disorders, changes in hormone levels, inflammation and the use of certain medications can cause sporadic dark spots to form on face, neck and arms.

There are many types of hyperpigmentation, but melasma, sun spots and post-inflammatory hyperpigmentation are the most common skin pigmentation problems.

Beisdes looking unsightly, hyerpigmentation may also reflect some underlying, larger and more serious health problems. Therefore, whether from a beauty or health perspective, it is important to seek professional diagnosis and treatment.

Types of pigmentation


This is the most challenging skin pigmentation condition for patients and doctors. This is because this chronic skin disease has many unstable factors and is prone to recurrence. It is a progressive pigmented skin disease, and heredity, sun exposure, female hormones, birth control pills or pregnancy are common predisposing factors.

Melasma mainly appears as brown or brown-gray patches on different parts of the face, such as the forehead, cheeks, bridge of the nose, upper lip and chin. Of course, it cannot be ruled out that melasma will occur in other parts of the body, such as the neck and arms.

Sun spots

Also known as freckles or age spots, sun spots are dark patches of skin that form on the surface of the skin due to excessive exposure to ultraviolet radiation. Ultraviolet rays activate skin melanocytes, causing melanin to accumulate within keratinocytes or skin cells. Because this skin condition is common in middle-aged people over 40 years old, sun spots are also called “age spots.”

Post-inflammatory hyperpigmentation (PIH)

This type of hyperpigmentation occurs when inflammation caused by skin injury, such as acne, cuts or burns, irritates the skin, leading to the production of melanin, which in turn causes spots. This skin problem is more common in people with darker skin.

Analysis of laser equipment

With the development of laser technology and research, many types of lasers have been developed to treat different aspects of skin pigmentation problems. Some of the highly regarded laser instruments include:

Long pulse ND:YAG laser – This is a typical non-ablative laser that can stimulate collagen regeneration, tighten pores, and help restore the original elasticity and firmness of the skin.

Nanosecond Q-switched Nd:YAG laser – This is particularly effective for treating superficial and deeper patches of discolored skin. It emits two wavelengths in the form of nanosecond pulses to target specific pigment spots. The two wavelengths are a 532 nm wavelength beam for treating superficial skin damage and a 1064 nm wavelength beam for deeper skin damage.
