I’m going for photorejuvenation tomorrow! Are you going or not!” “Huh? I heard that photorejuvenation can damage the skin, or do not want to” “You have heard it all from hearsay, photorejuvenation does not damage the skin, I’d better explain it to you in detail” What is photorejuvenation photorejuvenation is called Intense Pulsed Light ( IPL), directly translated is Intense Pulsed Light, is a non-exfoliative physical therapy, many people will confuse Intense Pulsed Light and laser, but the two are very different. Laser is monochromatic, that is, each laser has only one wavelength; but intense pulsed light can simultaneously emit a variety of wavelengths of light, which is a broad-spectrum light wave, can cover a variety of target chromophores, such as melanin, oxidized hemoglobin, water and so on, more than one absorption peak. Pulsed light/intense light/OPT/DPL/color light are different names for photons. Technical principle Selective photothermal action principle. The longer wavelengths of light in the output of intense pulsed light can penetrate into the deeper tissues of the skin to produce photothermal effect and photochemical effect, so that the collagen fibers and elastic fibers of the skin are rearranged and regenerated to restore the elasticity, so as to achieve the therapeutic effect of eliminating or alleviating wrinkles. Photorejuvenation seven effects 1, remove or lighten a variety of pigmentation and age spots 2, remove facial redness (capillary dilatation) and rosacea 3, smoothing fine wrinkles 4, shrinking large pores, thickening the collagen layer of the skin, and enhance the elasticity of the skin 5, effectively lighten the face of yellowish gas and dark circles under the eyes 6, significant improvement in the roughness of the facial skin condition 7, eliminating or lightening of acne scars Misunderstanding of photorejuvenation 1, photon Skin rejuvenation will make the skin thin In fact, it is not, intense pulsed light (photorejuvenation) can activate the fibroblasts in the skin, increase the synthesis of collagen fibers and elastic fibers, hyaluronic acid (hyaluronic acid). After these newborn collagen and elastin are rearranged, the skin becomes more elastic, shiny and tight, wrinkles are reduced and pores are detailed. Therefore, laser cosmetic surgery will not only not make the skin thinner, but also increase the thickness of the skin, and make it tighter and more elastic, and transform to rejuvenation. 2, photorejuvenation will make the skin sensitive The fact is far from it. Photorejuvenation although in the short term (7 days after surgery) will accelerate the evaporation of water because of the role of photothermal, to promote the exfoliation of the stratum corneum, and sometimes the formation of small micro-scabs. However, all the “damage” is under control and will recover after 7 days. The newly healed skin is structurally sound (including the stratum corneum, which is replaced even without treatment) and functionally healthy, so photorejuvenation does not sensitize the skin. Intense pulsed light repairs inflamed skin, reduces the release of inflammatory mediators, removes excess redness, and enhances skin metabolism. So instead of making the skin more sensitive, Intense Pulsed Light can treat the underlying conditions that cause skin sensitivity – seborrheic dermatitis, hormone-dependent dermatitis, acne and rosacea.
