In the field of medical beauty, photorejuvenation has become a popular project with its advantages such as affordable price, comfortable treatment experience, wide range of indications and short recovery period. However, some people who seek beauty will experience scabs and peeling after treatment. Is this normal? Is intervention necessary?

TECHNICAL PRINCIPLE

Technical Principles and Mechanisms of Photorejuvenation

Photorejuvenation is a technology that uses intense pulsed light to treat the skin. When intense pulsed light of a specific wavelength irradiates the skin, pigment particles, hemoglobin and other components in the skin absorb light energy, thereby producing photothermal and photochemical effects. These effects can stimulate the proliferation and rearrangement of skin collagen, thereby achieving cosmetic effects such as improving skin pigmentation, reducing wrinkles, and shrinking pores.

Take the phototherapy miracle egg as an example. Its 9 sets of filters can intercept light of different wavelengths and accurately treat different skin tissue problems such as acne, vascular problems, pigment problems, dark skin, hair and skin tightening.

CAUSE OF FORMATION

Cause of scabbing and peeling after photorejuvenation

Generally speaking, slight scabbing and peeling after treatment is normal. The main reasons are as follows:

The photothermal stimulation produced by photorejuvenation not only acts on the target tissue, but also affects the overall metabolism of the skin, accelerating the proliferation and differentiation of skin cells. Basal layer cells divide faster to produce new keratinocytes. These new cells move upward, causing the aging and damaged keratinocytes to fall off faster, which manifests as peeling. In addition, the evaporation of skin moisture may increase after treatment. If the skin is not moisturized enough, the water content of the stratum corneum will decrease, which will aggravate the symptoms of peeling.

Excessive energy density or mismatched parameter settings may also cause scabs, peeling, acne and other problems.

For mild scabs and peeling, they will usually fall off naturally within 1 week. This is a normal process of skin repair and no special treatment is required. However, the following matters should be noted:

Mild scabs and peeling may be accompanied by itching. Do not scratch with your hands to avoid damaging the scabs and causing pigmentation.

If the scabs are accompanied by redness, swelling or pain, apply cold compress appropriately to relieve discomfort.

After the scab falls off, the new skin is delicate and vulnerable to ultraviolet damage. Strict sun protection measures should be taken and moisturizing and repair products should be used appropriately.

If the scab is thick, red, swollen, painful, or lasts for more than 2 weeks without recovery, you need to be alert to infection and excessive damage. You should go to the hospital for a face-to-face consultation in time. Depending on the specific situation, you may need to use topical creams or oral related drugs for treatment.

Each beauty seeker has different skin conditions and different responses to photorejuvenation. For example, people with thin stratum corneum or dark skin have a stronger ability to absorb photons, which may lead to excessive local energy; unconsciously dodging the treatment head during treatment or the treatment head not fitting closely to the skin will reduce the cooling effect and increase the probability of epidermal burns and scabs.

Energy is the key factor in the action of photons. Within a certain range, the greater the energy, the better the effect, but the greater the damage, so it is crucial to find a balance between the two. Before treatment, it is necessary to comprehensively consider factors such as skin type, lesion type, location, depth, color, etc., and select appropriate treatment parameters, which plays a vital role in the treatment results.
