When acne friends see acne friends, their faces are glossy.
Acne is a skin problem that troubles many people.
Some friends have tried many methods, but they have not achieved particularly significant results.
Nowadays, medical beauty is becoming more and more popular. We can often see medical beauty terms such as red and blue light, photon rejuvenation and so on on the Internet, which makes some people seem to see a glimmer of light.
What is the therapeutic effect of these physical methods? Which treatment is more suitable for your condition? Today we will talk about it.
First, which situations can physical therapy be selected?
Acne, also known as acne, is a chronic inflammatory disease that occurs in hair follicles and sebaceous glands.
External drugs are conventional methods to treat acne, such as applying tretinoin cream to prevent the formation of tiny acne, using benzoyl peroxide and external antibiotic cream to prevent infection, etc.
However, these topical drugs are only suitable for mild to moderate acne, and may have certain irritation to the skin, and the drug effect may also weaken after being used for a period of time.
Further treatment includes oral antibiotics, isotretinoin and contraceptives. It usually takes a long period of time and is easy to relapse after withdrawal.
Physiotherapy can be considered when the following situations occur:
-
The curative effect of trying various oral and external treatments is getting worse and worse.
-
External drugs are too irritating and the skin cannot tolerate them, and they are worried about the side effects of taking the drugs or obvious adverse reactions after taking them.
-
The degree of acne is relatively severe, and pockmarks and pits are left after healing.
Common physical therapies for acne are usually related to light, so people who are sensitive to light, are taking photosensitive drugs or suffer from light-sensitive diseases such as systemic lupus erythematosus are not suitable for use.
II. Red and Blue Light and Photodynamic Therapy
Red and blue light therapy is a commonly used physical method to assist in the treatment of acne.
Propionibacterium acnes, one of the important factors in the formation of acne, produces a substance called porphyrin, which can absorb light with wavelengths of 400-700 nm. Red light has a wavelength of about 630 nm and blue light is about 410 nm, both in this band.
After the skin is irradiated with these two light sources respectively or in combination, porphyrin will absorb the light sources and produce singlet oxygen and free radicals, thus rapidly killing Propionibacterium acnes.
[Photodynamic therapy] can make the sterilization effect better: first apply photosensitizer (such as aminolevulinic acid) to the skin with acne, and then illuminate light (usually red light or blue light), which can further enhance the effect of light and inactivate more Propionibacterium acne.
Photodynamic therapy is especially suitable for moderate to severe acne, i.e. A large number of red papules, pustules, and multiple nodules and cysts on the face.
Slight pain, redness, exudation, scabbing, dryness, desquamation and pigmentation may occur after treatment. Some people may even suffer from acne aggravation after the first treatment.
The price of a single treatment ranges from 1,000 yuan to 3,000 yuan.
Three, photon rejuvenation
Intense pulse light therapy, which is what we often hear about photon rejuvenation.
The wavelength of intense pulsed light is 500 ~ 1 200 nm. Using different wavelength filters, the instrument can emit intense pulsed light with different wavelengths.
Strong light of different wavelengths can act on melanin, water, hemoglobin and other places of skin respectively to achieve the purposes of diminishing inflammation and controlling acne, fading acne marks, regulating oil secretion, preventing recurrence and the like.
After treatment, temporary flushing or slight burning sensation of skin will occur, and very few people may cause scabbing and pigmentation.
After treatment, attention should be paid to preventing sunscreen. You can apply sunscreen and use sunglasses, masks, hats, sunshades, etc. to shield it.
At present, the single treatment price of photon rejuvenation ranges from 1,000 yuan to 3,000 yuan.
4. Lattice Laser
When the acne problem is controlled, collagen and other tissues will be damaged due to serious inflammatory reaction, which will form some acne pits and require dot matrix laser treatment.
Through the matrix arrangement mode, the laser beam is divided into thousands of tiny beams to recreate uniform and tiny thermal damage on the skin. The thermal action stimulates the reconstruction of dermal collagen and grinds the uneven epidermis layer at the same time, thus gradually restoring the uneven pits to flatness.
After treatment, facial skin will become red and swollen and slightly painful, lasting for 2-3 days. After that, scabs gradually begin to form, and skin dryness, desquamation and mild pruritus may occur within 1 week.
The single treatment price of dot matrix laser ranges from 2,000 yuan to 5,000 yuan.
Acne is a skin disease, which is easy to repeat and lasts for a long time. It is suggested to find a professional dermatologist for standardized treatment, which can basically be well controlled.
It is not recommended to use the so-called acne removal products at will, or to carry out needle cleaning in irregular institutions, smear folk remedies with unknown ingredients, etc., which will delay the best treatment time, lead to scar generation, and may also make skin sensitive and fragile.
