In what situations can it be done? How good is the effect? What should I pay attention to?”
The “laser” that everyone refers to is actually a general term, and the correct name is “photoelectric technology”.
intense pulsed light
First of all, let’s introduce intense pulsed light, also called “photo rejuvenation”. It is not a laser in the true sense, but it is also used to treat skin problems through light.
Scope of application and treatment:
Intense pulsed light therapy is generally started once a month for 3 consecutive times.
If you want to achieve the best results, it is recommended to do it 3 to 5 times in a row and then every 3 months or half a year to consolidate it.
1.Enlarged pores will improve after 3-4 times;
2.Acne will improve after 2-3 times;
3.Redness 3-4 times, the local area can be basically removed, and the whole face needs more times;
4.Freckles are effective after 2-3 treatments, and they can be basically eliminated after 3 treatments;
5.Age spots 5-6 times can only lighten, but cannot be cured;
6.Pigmentation after trauma and burn 2-3 times.
The following is the effect diagram:

How it works:
Intense pulsed light is a kind of strong light emitted in a pulsed manner, with a wavelength of 400~1200nm, and the wavelength ranges from blue light, green light, yellow light to red light and near-infrared light. Different wavelengths of light correspond to different target tissues, such as melanin, hemoglobin, oxygen, etc.
Various wavelengths have corresponding filters
How various functions are implemented:
1.Remove red blood: Selective photothermal is absorbed by hemoglobin in capillaries, laser energy is converted into heat, causing target blood vessels to coagulate, multi-pulse damage to blood vessel walls, thereby inhibiting scarring, also for telangiectasia, rosacea, etc. has an effect.
2.Freckle removal: selectively act on melanin, and use the principles of “photothermal”, “photolysis”, “photoblasting” to rupture and decompose pigment clusters and pigment cells, so as to achieve the effect of removing pigment, such as: pigment after burn Calmness, stains, etc.
3.Skin rejuvenation and pore shrinkage: It acts on skin tissue to produce photothermal effect and photochemistry, rearranges collagen fibers and elastic fibers, and restores elasticity. It can eliminate or reduce wrinkles, reduce pores, and increase the thickness and elasticity of the skin’s dermis.
4.Acne, allergies: The light-adjusting effect of photons can kill the propionic acid bacteria that cause acne, accelerate the subsidence of inflammation, and can also shrink the sebaceous glands to destroy the anaerobic environment required for bacterial reproduction, thereby reducing the occurrence of acne. Such as: mild to moderate inflammatory acne, sensitive skin, photoaging.
Post-operative precautions:
1.Immediate reaction after operation: redness, burning sensation, darkening of pigment, etc. are all normal reactions, and local cold compress and facial mask can be applied;
2.Strict sun protection: avoid direct sunlight, use an umbrella, wear a mask, sunglasses, and apply sunscreen (SPF30-50) when going out;
3.Moisturizing and moisturizing: the ingredients are simple, avoid the use of functional cosmetics such as whitening and freckle removal for 3-5 days;
Contraindications:
Let’s take a look at when IPL therapy is not suitable.
1.History of sun exposure 3-4 weeks before treatment;
2.Skin diseases in the treatment area, such as: vitiligo, psoriasis, herpes simplex, photosensitivity, etc.
There is also a more common question, whether melasma can be treated with intense pulsed light?
It should be said that the use of intense pulsed light in the treatment of melasma is not very effective. It is recommended to use picosecond or oral tranexamic acid, which is more effective.
