Intense Pulsed Light is a type of treatment similar to laser, which can be used to remove spots on the skin, fight wrinkles and expression lines and remove unwanted hair throughout the body, especially on the face, chest, abdomen, arms, armpits , groins and legs.
Treatments with Intense Pulsed Light are safe and several scientific studies have shown that even months after treatment sessions there is no increase in the defense cells CD4 and CD8 that are related to the presence of diseases and cancerous tumors.
Some of the Pulsed Light indications are:
1. Prolonged hair removal
Intense pulsed light (IPL) can be used to remove unwanted hair from the entire body, but it should not be applied in some regions such as around the nipples and around the anus because the skin color in these regions is very variable and can spots or burns on the skin may occur. However, it can be applied to the face, armpits, belly, back, groin, arms and legs.
Hair can be removed completely, but better results are seen in people who have light skin and very dark hair. This is because the darker the hair, the greater the amount of melanin it has and how the laser is attracted to the melanin, when the hair is very dark, the incidence of light goes directly to it, weakening the follicle, thus eliminating the greater part of the body hair. About 10 sessions are recommended, with an interval of 1 month between them, which is the time necessary for the hair to be in the anagen phase, which is when the IPL has the most effect.
Unlike the permanent hair removal that is done with the laser, the Intense Pulsed Light cannot completely remove the hair, and therefore it cannot be considered a permanent hair removal, but it can also eliminate a good part of the hair, and those that are born after the end of treatment are thinner and clearer, becoming very discreet and easier to remove with tweezers, for example.
2. Elimination of wrinkles and expression lines
Expression lines can be completely removed and wrinkles can be reduced with the use of the Pulsed Intense Light device, because this treatment promotes an increase in the amount of collagen fibers and better organization of the elastin fibers that support the skin, and which normally has its production decreased, with age, from the age of 30.
The increase in these cells is progressive, so after each treatment session, the cells continue to be produced naturally by the body for about 3 months, so the results are not immediate, but are maintained for long periods. So, a good strategy is to do 5 sessions each year to completely eliminate wrinkles and fine lines. The interval between sessions should be 1 month.
You should use sunscreen above SPF 30 strictly for 7-10 days before and after treatment with LIP.
3. Combating rosacea and telangiectasis
The reddish skin and the presence of small blood vessels, under the skin that mainly affects the nose and cheeks, may indicate a skin problem called rosacea, and these small vessels in the nose indicate Telangiectasia, and both can be resolved with a treatment. with Intense Pulsed Light, because the light and energy emitted by the device promote a better reorganization of cells and distribution of small blood vessels.
3-4 sessions are necessary, with an interval of 1 month between them, and a 50% reduction is usually observed already in the second treatment session. There are no adverse effects of this treatment, the skin is only pink in the treated area in the first hours, but there are no scars or spots on the spot.
4. Acne treatment
The treatment with Intense Pulsed Light also eliminates acne when the equipment’s green or red lights are used. While green light eliminates the bacteria that is related to acne, which is Propionibacterium acnes , red light fights inflammation, which is important for the complete destruction of this bacterium. 3-6 treatment sessions are required and many people report that there is an 80% improvement after the third session.
However, pulsed light cannot be used when the person is taking medications such as Roacutan (isotretinoin), corticosteroids, acetylsalicylic acid, non-hormonal anti-inflammatory drugs, photosensitizers or when the skin is tanned. Learn about other treatment options .
5. Elimination of stretch marks
Intense Pulsed Light is also a good treatment for recent stretch marks that are reddish because it stimulates fibroblasts to produce collagen fibers and reorganize them in the stroma. With this technique, a reduction in the amount of stretch marks is observed and also a decrease in its width and length. However, better results are obtained when, after the session, complementary means are used, such as acids such as tretinoin or glycolic acid, for example.

6. Removing dark circles
Intense Pulsed Light also has excellent results in the elimination of dark circles, achieving excellent results when the dark circles are caused by vascular congestion, whereas in dark circles of hereditary origin the results may not have great significance. At least 3 sessions with an interval of 1 month are necessary to achieve the results.
After the session, it is normal for the treated skin to be a little red in the first hours, and may remain for up to 3 days, and there may be formation of small scabs that should not be removed with the nails.
7. Removal of skin blemishes
This technique is also indicated to remove dark spots on the skin, even in case of melasma, but it can also be indicated in case of solar lentigo and melanocytic nevus. Treatment with pulsed light brightens the skin, increases the amount of collagen and elastin fibers by 50%, leaving the skin firmer and less flabby, in addition to also increasing the presence of small vessels in the skin, which improve local blood oxygenation, giving a uniform tone and a more youthful and beautiful skin.
Treatment sessions should take place about 3-4 weeks apart and during treatment, daily use of SPF sunscreen above 30, on the face, and avoid direct sun exposure is recommended. After the first sessions, dark spots may appear in the treated area, which are called transient post-inflammatory hyperpigmentation, but when taking daily skin care and using soothing lotion after treatment, they tend to disappear. Using bleaching lotion for 1 month before starting treatment can decrease the risk of blemishes after treatment.
In addition to these 7 most common indications, IPL is also indicated in several other situations, such as, for example, the removal of burn scars, decreased keloid size and thickness, lupus pernio, lichen planus, psoriasis and hair removal in the sacroiliac region due to the pilonidal cyst, among others. Treatment with Intense Pulsed Light must be carried out with a trained professional such as a dermatologist or physiotherapist specialized in functional dermato because it has many details that can compromise the results of the treatment.
