XX friend told me that his skin became thin and sensitive after laser/photorejuvenation, so I didn’t dare to do it.
[Expert Review]
Not only will laser cosmetic treatment not make the skin thinner, but it will increase the thickness of the skin and make it tighter, more elastic, and transform towards youthfulness. After laser or photon treatment, the temporary damage to the skin barrier function is reversible, and because our skin has a strong ability to repair itself, your skin barrier can be repaired soon with the right care. Don’t give up the opportunity to make yourself more beautiful because you are afraid of the temporary “fragility”, this is to pick up the sesame seeds and lose the watermelon.
1.The principle of laser or photon beauty.
Pigmentation and vascular skin disease treatment principle is: selective photothermal principle, can “target treatment pigment”, and no damage or slight damage to the normal skin, so the skin will not thin; there are some diseases need to use exfoliative laser treatment, the epidermis has a certain degree of peeling, after treatment will have scab formation off, but Soon the skin can also regain its normal structure. The skin is divided into 3 layers: epidermis, dermis and subcutaneous tissue. The epidermis is composed of 4-5 cellular layers and is constantly renewing itself even without any treatment, with a cycle of about 1 month.
The dermis consists mainly of collagen fibers, reticular fibers and elastin fibers. Our skin has a very strong recovery function and self-renewal ability. With proper care after laser surgery, the recovery of skin structure and function is not a problem.
2. Temporary damage to the skin barrier function can be repaired.
Due to its thermal effect, pressure effect and photochemical effect, the stratum corneum, sebaceous membrane and the “brick wall structure” of the skin will be slightly damaged during the treatment process. The human skin has a strong self-healing ability, and the skin barrier can be restored soon by choosing the appropriate medical skin care products for effective skin care (moisturizing, anti-inflammatory, repairing, sun protection) according to the dermatologist’s advice within 3 to 6 months after the treatment. The time required for recovery is related to multiple factors: laser equipment, treatment physician, patient’s personal condition, physical condition and living habits, post-operative care, etc.
3, laser stimulates collagen production, but can make the skin thicker.
The actual “original protein” to the skin how important, the so-called is well-known. In fact, after 25 years old our skin with the growth of age, collagen and elastin loss, skin will gradually become thinner. You can obviously feel the skin of the elderly is very thin.
The laser not only lightens pigmentation, removes small dilated blood vessels, repairs photodamaged skin and improves the appearance of the skin through selective photothermal action. At the same time, it activates skin fibroblasts, increases collagen expression, produces molecular structure changes in dermal collagen fibers and elastic fibers, increases their number, rearranges them, restores skin elasticity and increases dermal thickness while also achieving the effect of reducing wrinkles and pores. This is why the laser has the role of skin rejuvenation.
4, then why would they say that they will become thinner after doing it?
First of all, you have to ask her whether she did it in a beauty salon or a regular hospital. The beauty parlors are looking for maximum profit, they prefer you to have frequent treatments, ignoring the fact that it takes time for the skin to recover itself, so laser treatments should have a certain interval.
Secondly, whether the laser done is exfoliating or non-exfoliating. The representative of exfoliating laser is CO2 fractional laser, which will scab off after treatment. This type of treatment is more traumatic to the skin, and the skin takes longer to repair than non-exfoliating laser. Therefore the interval time is slightly longer than phototherapy.
In addition, post-operative care is also important.
An example is given below.
Controlling acne conditions as early as possible is naturally the best way to prevent scar formation, but once a true scar is formed, there is no treatment that is too effective. Atrophic scarring, a type of scarring that is difficult to treat, manifests itself as an assortment of depressed acne pits. These scars are difficult to fade on their own, and basically the only way to improve their appearance is to undergo laser treatment, of which the best treatment is fractional laser. The best treatment is the fractional laser. It takes about once every 3 months, and several treatments are needed, usually 3-5 times to get some degree of improvement.
The principle of laser treatment for pigmentation is selective photothermal action, which can “target the pigment” with little or no damage to normal skin. CO2 laser treatment is based on the principle of focal photothermal action. As we can see in the picture below, the laser penetrates the epidermis and part of the dermis with a certain density and evenly, forming very small “pores”, which evenly initiate the skin repair process, remodeling and rebuilding the epidermis and dermis, and the effect lasts up to 3 months after the procedure. This suggests that it is not necessary to treat too frequently to improve the efficacy of the treatment, and to give the skin a longer “vacation” to restore its normal structure and function.
Immediately after the ablative fractional laser treatment, uniformly arranged dots on the skin can be observed, which are produced by vaporization. The picture below shows the rapid recovery of the skin after fractional laser treatment.
How should I care for my skin after surgery?
Immediate treatment: After vaporized fractional laser treatment, the skin will have varying degrees of burning, pain, erythema, edema, and exudation, which require immediate cold compresses, usually for 20-30 minutes. A temperature of about 4 degrees is more appropriate. Cold compresses are good for promoting the release of excess heat and alleviating some discomfort. After the cold compress, some medical face film and cold spray can be applied.
2 weeks after surgery: Special care is needed within 2 weeks after surgery. It is recommended that if there is a break in the epidermis, do not touch the water for the first 3 days to prevent infection. After 3 days, try to wash gently with water only, do not rub hard and use cleansers such as facial wash and soap. Let the scab fall off naturally, prematurely tearing off the scab can easily lead to pigmentation spots. At this time, the wound can be topically applied with growth factors and some anti-infection drugs. Some masks with restorative functions are also available.
Within 3 months to 6 months after surgery: Since laser surgery injures the skin barrier to a certain extent, it is very necessary to use suitable medical skin care products for effective skin care (moisturizing, emollient, anti-inflammatory, restorative and sun protection) within 3 months to 6 months after treatment to promote skin regeneration and repair.
The importance of sun protection: Since post-laser surgery is prone to hyperpigmentation, it is important to protect the skin from the sun. Specific sun protection measures are explained in detail in this book.
From our treatment experience and related information, it is likely that less than 10% of people will experience temporary skin sensitivity after fractional laser treatment. If skin irritation occurs, please inform your doctor, who will give you the correct instructions and all recover quickly.
【Opinion】
Laser treatment can stimulate the formation of new collagen fibers in the dermis, and the skin will become thicker, so there is no need to worry about the saying that the skin will become thinner.
