Frequently Asked Questions


How does a laser hair removal system work?

When the laser beam is projected at the skin and the hair follicle, heat is created when the laser meets a dark matter (the hair). This heat when concentrated at the hair follicle will damage it, causing the hair not to regrow.

Does it hurt when being lasered?

Unfortunately, even when it is frequently asked, there is no absolute answer to that question. Because the feeling changes depends on the lasers used, body areas treated, and sensitivity of patients. At sensitive skin areas like when removing hair from upper leg thigh it will hurt more than knee area and lower legs.

People who undertook laser treatments have mentioned feeling some kind of slight needle pinching, rubber band snapping, concentrated heat like when focusing sun light with magnifying glass pulses. Some feel a light burning feeling. Generally, it’s uncomfortable at times, but with some anesthetics not a pain that a person can’t handle.

What areas of the body can be treated?

Any area of the body can be treated, the most common areas are the arms, legs, face (eyebrows, mustache, sideburns) neck, back, chest, feet, armpits, and bikini area.

Can laser hair removal cause skin cancer?

No. It will be the sun who will bring you the skin cancer, (if you walk unprotected). It is highly recommended to avoid the sun rays after laser treatment after your skin had been bombarded by light and melanin cells might be damaged.

Are chemical peels painful?

In general, patients only feel a mild stinging sensation during light or medium chemical peels. After the procedure, qualified staff may prescribe a mild pain reliever to relieve any discomfort.

How long is the recovery period after a skin peel?

The recovery time after a chemical peel depends on the type of peel administered, because each type of peel affects the skin to a different degree.

  • Light chemical peels: No recovery time
  • Medium chemical peels: About two weeks after treatment
  • Deep chemical peels: Complete healing can take two months or longer.

How does the laser work on skin?

The lasers emit a beam of light that is absorbed by melanin (pigment) in the skin and blood in the vessel. This will either break down the melanin or collapse the blood vessel, getting rid of pigmented lesions (age spots, sun spots, seborrheic keratoses, freckles, dermatosis papulosis nigra) and vascular lesions ( facial spider veins, cherry angiomas, spider angiomas, broken capillaries, rosacea).

For acne, the laser targets porphyrin to cause the formation of free radicals which ultimately eliminate the acne’s bacteria.

What should patients expect?

Treatment may vary, depending upon patient characteristics and the area being treated. Eyewear is placed to protect the eyes. The skincare professional wears a polarizing headlamp that helps visualize the target area and the effect of the laser beam. A handpiece is used to direct the laser beam to the specific area. Some patients report a stinging sensation during the treatment.

There can be some redness which usually goes away in two to three hours and swelling, if any, may last one to two days.

Final treatment results should be evident within 10-14 days for vascular lesions and 10-21 days for pigmented lesions.

Results for acne vary.

Sunscreen must be worn after the treatment.

Is laser skin treatment suitable for severe acne?

Yes. Studies have shown that it can effectively reduce and eliminate severe acne.

Are there side effects from injectable fillers?

Side effects tend to be minimal with most injectable fillers. Bruising, swelling and redness may occur but typically fade within one to two days. Normal activities, including work, can usually be resumed right away.

Results are temporary for most injectable fillers and will require periodic repeat treatment in order to maintain the effect.

How long do injectable treatments take to administer?

Injectable fillers usually take no more than forty-five minutes to complete. Some injectables will require multiple treatments spaced several weeks apart. A local or topical anesthetic or numbing agent may be administered before the filler is injected with a small needle beneath the skin of the treatment area.

Are dermal fillers just for filling lines?

No. Dermal fillers can not only fill wrinkles and folds but it can also non-surgically lift the brows (brow lift), fill the hollows under the eyes, and augment the cheeks and chin.

It is also a popular treatment to boost the volume in the lips.
