Test Patch: What to Look For

  • Test patches are carried out to determine the skin’s reaction and starting treatment parameters. We want to make sure that we are treating you safely and effectively.
  • Small areas of skin in the area are to be treated are tested and if no adverse reaction occurs after one week, then treatment can begin.
  • What we ask of you is to make a note of any redness or swelling and how long it takes the redness or swelling to reduce following the test patch, also whether the skin blisters or feels excessively hot and for how long.
  • Pre Treatment and Post Treatment advice needs to be followed

  • Photo-sensitising conditions (such as lupus, porphyria)
  • If you have a history of diseases stimulated by heat, such as recurrent Herpes Simplex in the treatment area, a prophylactic regime needs to be followed – prescribed Acyclovir must be taken for one week - before, on the day and after the treatment

Pre Treatment Instructions

Please:

  • Stop using prescribed retinoids (tretinoin) or other prescription grade actives such as Benzoyl Peroxide 2 weeks prior to treatment.
  • Avoid retinol, exfoliating acids and any other active skincare 5-7 days before your treatment, depending on strength
  • Avoid waxing the area 7 days prior to treatment.

Post Treatment Instructions

  • To minimise skin heating and to reduce the likelihood of skin reactions, the treatment area may be cooled before, during and after the procedure. If the area still feels hot at home, you can apply a cold flannel or cool pack. Do not allow ice packs or ice into direct contact with the skin.
  • Following treatment, the area may appear red and raised and you may experience a tingling sensation. This is completely normal and should settle over the next few days.
  • Occasionally you may experience swelling or bruising and this can last anything from 1-2 days up to 1-2 weeks. If you experience swelling, it is usually worse one to two days following treatment. If it follows a treatment to a facial area, sleeping with your head raised on pillows will minimise its appearance. Ice packs will also help to reduce the swelling. If your skin is particularly sensitive and prone to histamine reactions, you may also wish to consider taking an antihistamine medication.
  • Following vascular treatments, a bruise may appear at the treated area. This may last up to 15 days and as the bruise fades there may be brown discolouration of the skin. This usually fades in 1-3 months. When larger vessels are treated, they may take on a darker colour. Again, this may take up to four weeks to resolve as the body re-absorbs the damaged vessels.
  • Make-up can be applied after 12 hours if the skin is not sore
  • Care should be taken to avoid trauma to the treated area for 4 to 5 days
  • Avoid strenuous activities, sauna and steam, excessively hot baths, massaging etc for 24-48 hours.
  • Wash and bathe as normal but take cool showers rather than hot baths. The skin should be patted dry and not rubbed. Use a soothing serum or Aloe Vera gel to reduce irritation and keep the area moisturised and the skin protected. If there is any discomfort, treat the area as you would sunburn.
  • Use a sunscreen (SPF 30+) and protect the area from sunlight as much as possible between treatments and for at least one month after treatment ends. Failure to do this can lead to sunburn and hyper-pigmentation of the treated area. (Most cases of changes in pigmentation occur when the treated area has been exposed to sunlight or in people with darker skin types).
  • If blistering occurs, contact the clinic immediately for further advice. Keep the area clean and dry and allow it to heal naturally. Do not use any lotions or creams on open skin as this may increase the risk of infection. DO NOT pick grazes or blisters – as this may increase the chance of a scar occurring. Once the skin has healed, a high protection sunscreen should be used daily for 12 months to prevent pigmentation changes to the skin.
