The
response to treatment and healing process after laser treatments varies
with several factors including skin color and location.
If you experience some itching after
treatment, moisturize treatment area. If itchiness is severe, try
"over-the-counter" antihistamine (i.e. Benadryl). Redness and swelling
may last 1-3 days.
If blistering occurs, keep area clean and
apply antibiotic ointment until healed, usually 5-7 days
Visible stubble may occur in 2-3 weeks due to
hair being expelled or shed from disabled follicles
Specific instruction for 2 days post
treatment:
Gently apply pure aloe vera gel, or other bland
moisturizing cream to treated area until redness subsides
When showering and washing, gently pat dry and
do not rub.
Cold pack may be used to reduce any swelling or
tenderness for first 24 hrs. Tylenol (not Aspirin) can be taken for
pain or discomfort if required.
Avoid using any harsh or irritating topicals
in treatment area
Avoid internal and external heat sources, as
this may stimulate melanocytes, leading to hyper-pigmentation. (i.e. Hot
baths, sauna, extreme exercise, hot oven, etc.)
Precautions:
Avoid friction from clothing, rubbing,
scratching, and do not pick or remove scabs or crusts if they occur.
Where applicable, avoid make-up on the treated area if skin is broken.
If there are no scabs or blisters, make-up may be used but remove
gently.
Some blistering may occur in treatment area.
Crusts and scabs may develop but infection is rare after laser
treatment. Just keep wound clean and apply antibiotic ointment.
Avoid sun exposure for approximately 1 month
and use sun-block, to limit risk of hyper-pigmentation.
Reminder:
A "regrowth or stubble" may appear in1-3 weeks.
This not new hair but represents the old hair being expelled from the
follicle. This hair falls away from the skin with easy friction (i.e.
washcloth of soft puff in the shower)
After the first three treatments, which are
done 4-6 weeks apart depending on treatment area, subsequent treatments
are done, if and when regrowth apppears. The effects of further
treatments are cumulative, with an average of 4-6 treatments for body
areas, and 4-8 treatments for facial area.
Hair growth is also affected by factors such as
: age, ethnic background, sex, body size, hormones, and medical
conditions.
A small percentage of patients may be
non-responders and will experience significant regrowth even after
several treatments.
What to expect
after Laser Hair Removal Treatment
Avoid bathing or washing with very hot water.
Use tepid water
You may feel like you have a mild to moderate
sunburn. Minor crusting or minor peeling of the surface layers of the
skin is not unusual. Over the counter Hydrocortisone Cream and Aloe Vera
Gel may help with redness or inflammation of your skin.
Keep ther area clean. Wash gently.
Avoid direct sun exposure after your treatment.
If you do go in the sun, protect the treated area with sunscreen of 30
SPF or higher.
Do not shave the treated area for at least 4
days after treatment. Do not wax, pluck or use depilatories for the
hair that grows back. After laser treatment, hair may continue to grow
out as if it were never even treated. Typically this will occur for
about 2 weeks and then these hairs will simply begin to fall out.
Avoid any irritating medications or chemicals,
particularly on the face. Examples of these are Retin-A, Benzoyl
peroxide, glycolic acid or astringents.
Possible Side
Effects.
Hyper-pigmentation - dark spots in area of
treatment can occur as early as 3-4 days after treatment. Avoidance of
the sun, use of sunscreen, and bleaching cream if needed, Avoid
activities, which increase internal heat, i.e. Hot tubs, aerobics for
24-48 hrs post treatment. Darker skin types are at higher risk. May
take 2 weeks to 6 months to resolve.
Hypo-pigmentation - lightening of skin can
occur, especially in darker skin types. No treatment available. Usually
resolves within 6-12 months Sun Avoidance is critical.
Pinkness and tenderness (sunburn-like feeling)
occurs in most people for a short period of time (lasting several
hours to 2 days)
Textural changes - crusty, scabby roughness to
skin can occur within 3-4 days. Usually returns to normal with 10-14
days.
Purpura - reddish-brown tine "bruise like"
marking is rare but can occur. Resolves without treatment in about 2
weeks.
Scarring has not been seen to date but all
lasers have the potential to scar if not used with care or when used on
patients with contraindicating medical conditions (i.e. Accutane user).
It is prudent for full disclosure of medical history during
consultation, and any changes to medical history before each treatment.
Tattoos, freckles and dark moles may change
colors, this may be permanent. Rule out malignancy in all unusual
looking moles and nevi.
Treated hair can be slow to expel. It will take
longer to purge hair in certain areas and shaving immediately post
treatment may lend to ingrown hair.
Precautions and
Contraindications:
History of keloid scarring
Impaired healing - diabetes, dermatoses,
chemotherapy or radiation therapy
Photosensitizing medications
History of pigmentation problems - melasma,
vitiligo, post-inflammatory hyper-pigmentation
History of herpes simples periorally. Ajny
stimulation may cause eruption of cold sores.
Questionable moles or pigmented lesions
Tanned skin - natural sun, tanning bed, or
tanning lotion (treat at lower fluency)
Accutane use within 12 months of treatment -
predisposes risk to developing keloid scar from skin injury
Pretreatment Measures
Avoid active tanning (includes tanning beds)
for 3 days before and after treatment
Use a sunscreen on exposed areas, 15-30 SPF
(preferably with ingredients including titanium dioxide or zinc dioxide)
Avoid waxing, bleaching, depilatories, or
electrolysis for at least 4 weeks prior to treatment
Hyper-pigmented area can be treated with
Hydroqinone 4% for a few weeks before and after laser treatment to
inhibit melanin production as result of photo-stimulation. Continue to
shave for up to 2 days prior to treatment. Hair should only be 1-2 mm
length at time of treatment . For large treatment areas or areas
with high density , coarse hair , less stubble or surface hair is
ideal. (i.e. Men's back or women's bikini area)
If documentation photo are taken, they should
be compared to a baseline of photos of pre-treatment hair at full
growth, usually during time of consultation
Anti-viral prescription can be obtained from
doctor if there is a strong history of cold sore outbreak. Can usually
prevent an eruption if medication started at first sign of tingling on
lip. Can also be taken as prophylaxis when treating bikini area on
patient with history of herpes
Do treat when there is active herpes in
treatment area.
