레드 라이트 테라피 (RLT) can be helpful in treating Post-inflammatory Hyperpigmentation (PIH).Hyperpigmentation usually occurs after inflammation or trauma to the skin has healed, usually because the melanocytes in the skin are producing too much melanin.
Red Light Therapy penetrates the deeper layers of the skin with its specific wavelength of light (usually 630-650 나노미터) to stimulate the repair process of skin cells, improve blood circulation and increase collagen production.It also reduces skin inflammation and promotes skin healing. These effects help to reduce the appearance of hyperpigmentation, especially the discoloration associated with post-inflammatory hyperpigmentation.
Post-inflammatory Hyperpigmentation (PIH) is a localized accumulation of excessive melanin in the skin following the healing of an inflammatory skin condition or injury, which can lead to darkening of the skin or the formation of discoloration. It usually occurs after the skin has experienced some type of inflammation, such as acne, eczema, wound healing, sunburn, or other skin irritation.
What is post-inflammatory hyperpigmentation
Causes of post-inflammatory hyperpigmentation formation:
1. Inflammatory response: When inflammation occurs in the skin, skin cells (especially melanocytes) are activated to produce more melanin. The presence of inflammation stimulates the melanocytes to produce excessive amounts of melanin.
2. Skin Injury: Any type of skin injury, including acne, burns or cuts, can lead to localized excessive melanin deposition. This is because during the healing process, the skin undergoes repair and reconstruction, and additional melanin may be produced during this process.
3. UV Exposure: UV exposure can exacerbate hyperpigmentation, especially in areas of skin that are already damaged, and UV rays can stimulate melanin production, making hyperpigmentation more pronounced.
Characteristics:
Pigmentation or Uneven Skin Tone: Commonly presents as dark or brown spots on the skin, usually darker than the surrounding skin color.
Irregular Distribution: Pigmentation usually forms near areas of original inflammation and may appear on the face, chest, back, shoulders or extremities.
Is hyperpigmentation a scar?
Dark spots caused by post-inflammatory hyperpigmentation are often confused with scars; 하지만, these dark spots are very different from scars. When the dermis, or deeper layers of the skin, are damaged, the collagen matrix in the skin irregularly repairs itself, leaving lasting marks on the body. Scars are also usually raised (hypertrophic) or depressed (dystrophic), whereas dark spots caused by post-inflammatory hyperpigmentation are flat on the skin. In addition, many scars appear lighter than skin color, but this is not common.
While hyperpigmentation fades on its own after inflammation, although this can take some time, scars are more permanent. In hyperpigmented areas, the dermis of the skin is not actually damaged and the excess melanin is part of the healing process. Think of the skin’s response to UV (sunlight): melanin is produced to darken the skin and protect it from UV damage, as darker shades absorb less light. In the case of post-inflammatory hyperpigmentation, excess melanin prevents further UV damage.
Treatment of post-inflammatory hyperpigmentation
While post-inflammatory hyperpigmentation is part of the skin’s healing process, stubborn dark spots can be annoying or unwelcome. 하지만, there are many products that can help fade dark spots. A common topical treatment for dark spots is the use of retinol, an ingredient in many creams and serums, which increases collagen production and cell renewal. Many people who use retinol products experience redness and peeling of the skin, which is a sign of irritation from the product and a reason why some people abandon retinol treatments. These products are also quite expensive and can take up to 90 days to begin to show results.
How Red Light Therapy Improves Hyperpigmentation
Red light therapy treats a wide range of skin problems including acne, wrinkles, scars and sun damage. This therapy uses concentrated wavelengths of red light to stimulate cellular energy production, which creates a series of reactions to accelerate the natural healing process. Increased circulation helps deliver inflammatory mediators to damaged tissue for rapid anti-inflammation. In addition, red light therapy increases the production of collagen, the main component of our skin’s cellular matrix that helps maintain structure and elasticity.
We all have different skin, so it is important for skin treatments to be versatile and customized. Red light therapy can be customized for each individual, using a mix of different wavelengths, wattages (힘), and the use of continuous or pulsed light. In addition, light beds (such as the MERICAN Red light Therapy Bed m4n) can treat the entire body at once. This means you can address multiple areas of skin imperfections at once.
빨간불 치료 is a non-invasive treatment that does not cause the irritation and peeling that many people experience with retinoid products. In addition, many people begin to see results within the first few weeks of treatment.
