Dark Patches Following Light Treatments

A consent form for a light treatment should say what can be left behind on skin. This article sets one published sentence beside that clause, for a Ponte Vedra reader about to sign.

Safe for every skin tone, as a sales line

A clinic may say a treatment is "safe for every skin tone." The form is where that either holds up or does not. Read it for any line that mentions burns or marks.

What the AAD says

The AAD writes: "While lasers can be used on all skin types, darker skin is more prone to burns and dark marks after laser treatments." The sentence has two halves. The first allows laser use on all skin types. The second names burns and dark marks as a greater likelihood on darker skin.

A promise that quotes only the first half is leaving out the second. The sentence is about lasers, so ask whether the clinic's light device falls under the same warning.

Three things the clause should settle

• Who it covers. Does the form say which skin types the warning applies to?
• What it names. Does the form use the words "burns" or "dark marks," or a softer phrase?
• What it excludes. Does the form say what the clinic will not be responsible for?

A retrospective study of intense pulsed light for post-inflammatory erythema and hyperpigmentation names the treatment and the skin findings in its title, a habit a form can copy.

A reference on pigment after inflammation

For darker skin, a review of post-inflammatory hyperpigmentation in skin of color is another source to read beside a form. It lists treatment algorithms in its title.

Ask for the risk wording on paper

Ask the clinic to write down the risks that apply to your skin type, using the words "burns" and "dark marks" if they apply. Then ask what the clinic does if either happens.
