The most important thing is that you have to be able to get the most out of your skin. The following we look at the whitening principle of photorejuvenation.

The principle of photorejuvenation

Biostimulation

The skin absorbs different wavelengths of 7-color light and uses strong pulsed light to act directly on the skin. As the skin absorbs the strong pulsed light, a photochemical reaction occurs internally, especially the molecular structure of the collagen and elastic fibers in the dermis changes, restoring its elasticity and toughness, thus increasing the elasticity of the skin. In addition, using the photothermal effect of intense light waves, it can provide sufficient energy for blood vessels, enhance the function of blood vessels and improve blood circulation, thus eliminating wrinkles, shrinking hair vessels and making the skin tighter.

Photothermolysis of light

Skin lesions are characterized by pigmentation and capillary dilation caused by damage to the stratum corneum, so the lesioned skin shows more pigments than normal skin.

Indications for Photorejuvenation

Since the main working principle of photorejuvenation is biostimulation and pyrolysis, its scope of application is limited to the repair of skin pigments and epidermal capillary dilation. The main items of photorejuvenation are: small needle facelift, red blood, red acne marks, freckles, spot recuperation, acne, moles, facial burns, skin hair removal, fine wrinkle elimination, etc.

Post-operative care of photorejuvenation

1. Photorejuvenation is a minimally invasive surgical treatment, which is less harmful to human skin and does not require additional care under normal circumstances, it should be noted that many skin care products cannot be used casually and facial massage care cannot be done to avoid the appearance of red blood. 2. After photorejuvenation, you need to pay extra attention to sun protection to avoid re-deposition of pigments.

Who is not suitable for photorejuvenation

1. photosensitive people and patients with photosensitive drug applications: such people are sensitive to light and are prone to skin damage after treatment. 2. Pregnant women:Because there are varying degrees of pain associated with the treatment, potential effects on fetal development cannot be completely ruled out in theory. Systemic use of retinoic acid (at least 2 months after cessation of use before treatment). Such patients may have a potential temporary impairment of skin repair function. In most cases, photorejuvenation does not solve the melasma treatment problem, but sometimes makes the situation worse. 4. People with darker skin tone and prone to pigmentation should not use this method, it is easy to repeat or aggravate the pigmentation.
