Vithas Xanit International Hospital counts upon the Department of Ophthalmology, which as a benchmark in the region offers ophthalmological solutions based on the knowledge and experience of a great team of professionals, led by Dr Cilveti, along with advanced technology.

Our portfolio of services includes almost all diagnostic procedures and treatments available today, from clinical consultations to the therapeutic treatments required in each individual case.

Today, in our blog, we will learn a little bit more about one of the leading technologies available in our department, the femtosecond laser. A novel refractive surgery technique that allows us to correct pathologies related to vision, such as myopia, hyperopia, astigmatism or presbyopia affecting more than 50% of the population who otherwise are forced to wear glasses.

What is a femtosecond laser?

The femtosecond laser allows, among other interventions, to correct presbyopia (tired eyesight), as well as to correct refractive defects such as myopia, astigmatism or hyperopia.

How is it used?

The femtosecond laser penetrates transparent tissues and acts at a certain depth. At this depth, which can vary, the laser breaks some molecules of the tissue, thereby making cuts and sectioning the tissues.

In ophthalmology, the main uses of laser are to make cuts in the cornea at a certain depth and shape, like in refractive surgery, or also to completely section the cornea or treat the lens directly, like in cataract surgery.

What benefits does it have?

Precision and efficiency are the main advantages of laser techniques used here at Vithas Xanit International Hospital. Laser techniques allow treatment with minimised risk of infection, with minimal pain and without hospitalisation.

The femtosecond laser eliminates the risks of cuts made in the cornea with mechanical procedures used in other anatomical sites using a knife.

 

Frequently Asked Questions about Laser Hair Removal (Part III)

There are a lot of questions when it comes to laser hair removal, either due to lack of information or because of some particularities that each case entails. To shed some light on the subject, our specialists have collected the most frequently asked questions:

  1. Is there any guarantee that the treatment will be successful?

Once the specialist studies the type of hair and decides on an adequate laser, that will be the most effective and durable treatment available. It must be clear, however, that this is an almost definitive, but not entirely, epilating method. With laser hair treatment, most hair is removed, although in certain areas it results in a much lower density and some hair may remain. Besides, over time, it may be necessary to repeat the treatment, which depends on each case.

  1. Is it true that winter is the best time for laser hair removal? – Why?

It’s not really a matter of season as such but of sun exposure. Photo-epilation can be performed throughout the year, as long as sun exposure is avoided before and after treatment. Laser treatment can not be performed on recently tanned skin due to increased risk of burns. On the other hand, nowadays there are types of laser such as Diode or Neodymium Yag which are prepared to epilate any skin type, and not mostly brunettes as up to know, but even the black skin, with maximum safety and guarantee, although it is always advisable not to sunbathe 2-4 weeks before the treatment.

  1. How can hair colour influence treatment?

Hair colour and thickness are the most important factors for the effectiveness of laser hair removal. The laser targets the pigment (melanin) that exists in the hair and which, under normal conditions, is in higher concentration than in the surrounding tissues, so it is very important to assess the melanin charge of the patient’s hair correctly. The higher the concentration of melanin is (brown melanin), the greater is the ability to heat the follicular structures. Black or dark brown hair has a high pigment concentration and therefore absorbs energy better and is destroyed more easily than light hair. Fine hair with black or brown colour may be laser epilated, although it may require a greater number of sessions due to its lower melanin content. If we are dealing with a very blond or white hair, it cannot be laser-treated because it lacks melanin.

  1. How do you treat areas with tattoos or skin moles?

Regarding laser hair removal on tattooed skin, the short answer is that it cannot be done. To understand why, you must first understand how the treatment works: the laser does not target the real hair, but the pigment in the hair. Therefore, if the skin is tattooed, then the laser will also attack the pigment of the tattoo.

The laser will not only ruin the tattoo, but also cause a considerable amount of pain. When the pigment hits against the tattoo, it can cause severe burns or blisters.

If it is a very small tattoo (letters, symbols, etc) or polka dots, it is possible to paint them with a white pencil in such a way that it does not absorb the light and therefore the skin is not damaged.

  1. There is a widespread belief that getting facial hair epilated brings long-term face spots. What is the truth?

Laser hair treatment, in expert hands, is a safe method for hair removal without damaging the skin, although there are always risks associated, such as burns and temporary hyperpigmentation of the skin (spots), However, these are minimized as long as there is a supervision of a specialist in aesthetics, who determines all the parameters that a laser requires to work safely, based on the characteristics of the patient’s skin.

  1. What if I am under-age and want to undergo laser hair treatment?

The treatment is recommended for those over the age of 18 since there is greater hormonal stability, which allows better results in the long term. However, the procedure may be performed on under-age patients providing that they have the consent of their parents and are aware that they may need more sessions to achieve the desired result as the hair does not appear at the same time in all young people. Indeed, there is a range between the ages of 10 and 15 during which the hair is showing. Also, at the same age, one girl can be completely hairless, and another can have it fully developed. The treatment is not possible on all desired areas and in all people who would like to undergo the laser hair removal. The armpits and some areas of the legs usually have a good result if the hair has the right thickness; however, in other areas, it is not advisable to start early. However, with proper protocol and experience, laser hair removal in girls and adolescents is possible, the result is good and avoids the drawbacks of waxing and razor-shaving. Moreover, once they have started with the right laser treatment, there is no need to epilate using other methods and can stay 2-3 months without having to epilate because there is no hair.

And to finish this list of questions, we attach a statistical data that causes great curiosity.

  1. What are the areas that are mostly treated by men? What about women?

Men often request laser treatment on the back, shoulders, chest, abdomen and cheekbones. Areas with more pronounced hair density are always more uncomfortable. However, other areas such as the legs, neck, arms, buttocks or hands are also increasingly more requested.

As for women, at present, the most treated areas are the armpits, the groin and the legs. Be informed about these pieces of advice before your laser hair removal and the most sensitive areas to be treated.

 

Laser hair removal tips: What to do before and after treatment (Part II)

Are you thinking about having a laser hair removal treatment? We are aware that there are many doubts and uncertainties in this regard, so today we have asked Dr Monica Garcia Soto, from Vithas Xanit Aesthetic Dermatology Department, what pieces of practical advice we should bear in mind before and after laser hair removal.

 

Tips from our specialists, before and after laser hair removal treatment

BEFORE laser hair removal, you should avoid getting tanned or exposed to UV rays at least one month before treatment. This is due to the fact that the laser uses melanin from the hair as a conductor, and if the skin has melanin activated, there is a risk of burns. However, this is not necessary if using Diode Laser Depilatory System.

Also, you should not pluck your hair with tweezers or get it waxed, or use any other epilating method that pulls off the hair from the root. We have to make sure that for the first session you have not been epilated or shaved at all for at least 4 days before the session. Subsequently, you can shave your hair, but only with a razor, avoiding any other method that eliminates the hair directly from the root.

You must attend laser sessions with completely clean skin, without creams, self-tanning, deodorants, perfumes or makeup.

It is important to let us know if you are pregnant, if you are taking any medications, especially anti-contraceptive pills, hormonal treatments, acne treatment or any other. There are many drugs with photosensitive effects, so before starting a laser hair removal session it is necessary to indicate what medication you are on if any.

Any cream containing retinol or glycolic acid should also be discontinued at least 5 days before each laser session.

No hair bleaching should be done at least 4 or 5 days before each session.

It is also important to report whether you have or have had cold sores in the days prior to treatment.

It is necessary to moisturise the skin regularly.

 

AFTER laser hair removal treatment you should use restorative creams if there is any irritation on the skin, and you should be moisturising your skin for 3 or 4 days in any case. Avoid the use of alcohol-containing deodorants if the armpits have been treated. Avoid sun exposure at least 7 days after undergoing laser hair removal. It is recommended to use total-block sunscreens when sunbathing again. Hair should fall out within days of treatment and can be shaved with a razor only, never with wax or hair epilators.

It is advisable to avoid wearing too tight clothing over the treated areas, at least for about 3 days after treatment. It is also not advisable to apply heat to the treated area, have excessively hot showers, saunas, hot tubs and the like for 3 or 4 days after treatment.

After facial hair removal, you should avoid applying make-up on the area for a couple of days.

The waxed area should not be scratched or overtouched. Washing should be done with neutral soap and warm water, without rubbing too much to avoid irritations. Finally, you have to maintain constant and regular hydration of the treated area. This habit helps with irritation and discomfort that may appear, as well as to prepare the skin for the following sessions.
