Acne scars with pigmentation

Common acne scars are divided into two types: red acne scars (erythema after inflammation) and dark brown acne scars (pigmentation after inflammation).

In the initial stages of scar formation, they appear red due to the dilation of capillaries, also known as inflammatory acne scars. During the process of acne development, facial capillaries are repeatedly stimulated by bacteria and compressed by hypertrophic sebaceous glands. To allow blood to pass quickly and facilitate the rapid arrival of "rescue" cells at the damaged site, the capillaries gradually dilate. However, after the acne disappears, the capillaries do not immediately shrink, and blood flow slows down, causing red blood cells, platelets, and other components to easily accumulate locally, eventually forming red acne scars.

If proper sun protection measures are not taken, further damage to the skin can stimulate melanocytes to produce excessive melanin deposition in the epidermis or dermis, causing red acne scars to transform into dark pigmentation. This is an inflammatory response, where skin barrier damage due to external factors leads to acute and chronic inflammation, increasing the likelihood of pigmentation. The severity of pigmentation is not primarily determined by the degree of inflammation, but rather depends on individual factors.

The locations where dark brown acne scars can form typically undergo a process of "first turning red, then turning black." Initially, it is an inflammatory reaction, directly leading to blood vessel dilation and redness. However, when this chronic inflammation persists for some time, it stimulates melanocytes to produce melanin, resulting in pigmentation after inflammation, presenting as brown or black pigmentation.

1.Lumenis IPL M22

Introduction: The Stellar M22 is the latest upgraded version of the Stellar IPL photorejuvenation system released by Lumenis in 2020. It features IPL (Optimal Pulse Technology) and non-ablative fractional laser functionalities, with four handpieces offering over 600 different treatment mode combinations, effectively addressing more than 30 skin concerns.

OPT™ IPL is currently one of the most advanced and popular non-invasive photorejuvenation treatments. It utilizes the effects of intense pulsed light (IPL) generated by the M22 device to stimulate the skin, inducing molecular structural changes in the collagen and elastin fibers of the dermis, restoring their original elasticity, thereby achieving the treatment effects of wrinkle reduction and pore shrinking.

The greatest strength of the STELLAR M22 lies in its ability to adjust the intensity of light (wavelength) according to the skin using filters. A single treatment can provide dual irradiation to the face, with filters transmitting energy to the dermis to act on latent pigments deep in the skin. Subsequently, filters reacting to epidermal pigments are used, effectively improving pigmentation, freckles, and brightening the skin tone.

Suitable for:

• Individuals with common pigmentation issues such as freckles, sunspots, and age spots.

• Individuals with signs of skin photoaging.

• Those with vascular pigmentation issues.

• Individuals with mild pigmentation issues and skin accompanied by erythema or redness awaiting repair.

• Individuals seeking pigmentation correction as well as skin rejuvenation and whitening.

Microneedling involves the use of nano-level needles to create numerous tiny channels at different layers of the skin. These channels allow for the delivery of cell growth factors, active ingredients, and multiple nutrients to penetrate and be absorbed by skin cells at various depths, with an absorption efficiency close to 100%. It is 4000 times more effective than regular skincare.

Microneedling can rapidly activate cells and simultaneously promote the proliferation of collagen and elastin precursor cells. This helps to smooth out depressed scars, fade pigmentation, deeply hydrate the skin, reduce wrinkles, and ultimately improve skin texture, restoring it to a healthy state and achieving flawless porcelain-like skin.
