IPL & Laser Hair Removal Contraindications

IPL and Laser Hair Removal treatments are often perceived by the public to be routine beauty treatments. However, they are not.

Serious burns can occur if the client withholds information or if the therapist is inexperienced.

For that reason, it is vital that you read this list of known contraindications to better prepare you to receive or to perform a laser or IPL hair removal treatment.

Depilatory creams & sprays

Depilatory creams and sprays dissolve keratin. These chemicals are non-discriminatory and kill the keratin in skin as well as hair.

Minimal use of depilatory creams is enough to damage the skin, and therefore their use is a definite contraindication to treatment for fear of the risk of scarring. Clients who have used these products must wait six weeks from use before receiving a Pulsed Light or Laser treatment.

Suntan or fake tan

This is not to be confused with natural skin pigmentation, eg Mediterranean or Asian skins. Tans, whether caused by the sun, spray tans, or tanning moisturisers, place the melanin in the skin in an unnatural 'excited' state.

Since pulsed light and laser target melanin, this places the skin at risk of becoming an accidental target. This can lead to burns or pigment marks, and generally, ineffective treatments.

Secondly, excited skin is temporary. This means that the next time the client comes for treatment, their skin may be a different shade. This creates the need for experimenting with different filters from one treatment to the next, which basically requires the therapist to make a best guess at which filters to use each time.

Continuity is extremely important to compare the results from one treatment to the next, and tanning ruins this. When can a client tan? Fake tanning is fine after treatments, assuming that any residual heat has subsided. Clients should not use spray tans or tanning moisturisers for two weeks prior to next treatment, and any remnants should be completely exfoliated.

Clients must not get real suntans or use solariums for the entire duration of their course of treatments and for one month after their final treatment.

Dark skin

Where a client has a naturally darker complexion, eg they are of Mediterranean, Asian, Arab, or Indian complexion, they usually fall into a skin-type category of 4 or 5.

Unlike tanning, and assuming that the hair removal equipment is of even beauty-grade standard, natural pigmentation in the 4 to 5 scale should not be a contraindication to treatment.

Where a client who falls into this category has a tan in addition to their natural pigment, then they must lose their tan first so their skin returns to its normal state.

As a general rule of thumb, a category 4 client should receive a treatment using an 80% filter with no more than 50 Joules energy. A category 4 client will find a 100% filter at maximum 40 Joules most beneficial.

At any point during the course of treatments, if results appear to slow, DO NOT increase energy or decrease filters - Instead, use multiple shots of the area at the lower setting.

This will ensure that extra heat goes to the hair bulb without compromising the integrity of the skin. The same applies to treating genital skin on Caucasian clients, ie the labia, scrotum, perineum, and anal areas, which are invariably darker than surrounding skin on white-skinned people.

If a client is a skin type 5 or above, a small patch test must be carried out on an inconspicuous part of the body, then left for two weeks. If lightening or darkening of the skin is apparent, that person is not suitable for treatment

Recent waxing or plucking

Light-based hair removal requires a hair root to target. During waxing, plucking, or sugaring, the hair root is pulled out of the shaft.

If a client has recently used one of these hair removal methods on the area to be treated, they need to wait a minimum of two weeks for the hair root to regrow.

Contagious skin diseases or disorders

Some skin diseases are not easily detectable, and a therapist can only rely on client honesty. If a client discloses that they have a skin disease, and it is one that the therapist does not consider a contraindication to treatment, the following precautions must be taken:

Herpes 1 & 2

The concerns for Herpes is the same as other contagious skin diseases, however due to the heat caused during a treatment, it is your Duty of Care to inform the client that the treatment may cause an outbreak.

Visible skin trauma

If someone presents with visible skin trauma, the area is to be avoided.

Lesions, sores, and open wounds

If someone presents with lesions, sores or open wounds, the area is to be avoided.

Post-Surgical Scarring

Pulsed Light or Laser treatments of any kind will have a softening effect on scarring, however scars must be fully healed and closed. If any moisture or trauma is present, do not perform a treatment over the area.

Keloid or hypertrophic scarring

Clients who are genuinely prone to keloid or hypertrophic scarring must be thoroughly informed that there is a risk of skin trauma resultant from Pulsed Light or Laser, and that it is their decision if they go ahead with the treatment. Thorough notes should be kept on the details of the discussion between therapist and client.

Moles, freckles, skin marks

Pulsed Light and laser do not operate in the UV part of the light spectrum, and there is no evidence to suggest that such treatments can cause skin cancer or change the properties of a skin mark to make it cancerous.

It is not a therapist's place to diagnose any of the above skin conditions. It is however, a therapist's Duty of Care to tell the client if they notice a condition that may be suspicious.

It is a therapist's Duty of Care to inform the client that any marks in the treated area may fade, and thus make it more difficult for a GP to diagnose. When clients go to their GP for skin checkups, they should state that they have undergone a light-based treatment so that the doctor looks a little harder.

Sunburn

Skin showing signs of redness from sun or solarium exposure must not be treated with any form of hair removal until the skin calms down again. Usually this will take a week or two at the minimum, and up to several months where the skin has tanned significantly.

If the client has a residual tan, this will affect their skin typing, and must be taken into account before performing a Pulsed Light or Laser treatment.

Epilepsy or seizures caused by flashing light

Epilepsy and other types of seizures caused by flashing light are a contraindication for Pulsed Light or Laser, unless the client's GP provides a letter of authorisation.

When treating a client with epilepsy or seizures induced by flashing light, they must wear fully opaque 'swimming goggle' eye protection to block out 100% of light, preferably with a cotton pad or tissue beneath each lens to ensure client comfort and for added protection.

Pregnancy and breastfeeding

While there is no medical evidence to suggest that a Pulsed Light or Laser treatment can harm an unborn child, there is abundant evidence that the massive fluctuations in hormone levels during pregnancy and breastfeeding make any attempts to remove hair fruitless.

For ethical and client safety reasons, a therapist should not perform a light-based treatment until breastfeeding has ended and hormone levels have begun to settle again.

Polycystic Ovarian Syndrome (PCOS)

Refer to the separate article:

Hormone supplementing medications

This applies to anyone, male or female or trans, who takes hormone supplements or is on hormone replacement therapy. Examples:

Hirsutism

Hirsutism occurs in women who present with male hair growth patterns. There are two types of hirsutism: genetic and hormonal, and they are easy to differentiate.

A simple question - Does your mum, grandmother, or any or your aunts have facial hair? If yes, then the hirsutism is genetic.

If there is no family history of hirsutism, then the condition is most likely hormonal. Genetic Hirsutism is not a contraindication, but it should be treated as male hair. Hormonal Hirsutism will generally have an underlying cause that may be remedied with medical intervention.

If Hirsutism is present, therapists have a Duty of Care to inform clients that results will in all probability take longer.

Tattoos and permanent makeup

Do not go over any areas where there are tattoos, permanent makeup, or scalp micropigmentation. The light is attracted to tattoo ink. Hitting ink with IPL or laser will cause a severe burn and also ruin the tattoo.

Photo-sensitising creams, supplements, or medication

Black garments

Light attracts to darkness. Particularly in the case of nylon or polyester underwear and bras, pulsed light can melt the fabric onto the skin if accidental contact occurs. If working near these areas, have the client remove the garment and cover themselves with a towel instead.

Pain or excessive heat during treatment

While a small amount of mild discomfort is desirable during a pulsed light treatment, pain is a definite contraindication. Pain presents in various ways, including excessive sweating and body language, and it is the therapist's duty to observe how a client reacts during treatment and to constantly check that they are comfortable.

If pain is evident, whether the client says so or not, the setting must be reduced to a comfortable level, or else risk burning the skin.
