Dark hair - Darker colors of hair may
absorb more light, causing increased
warmth and decreased penetration of red
light. This effect is not likely to be large.
Melasma / Hyperpigmentation - Our own
product study showed improvement from
red and NIR light on hyperpigmentation,
particularly when paired with a high
antioxidant serum. However, in rare
instances users can experience the
opposite effect. We suggest starting
slowly and using red light only if this is a
concern.
A detailed discussion of this can be found
in our article: Red Light Therapy &
Hyperpigmentation.
Anyone with a contraindication to red
light therapy (or any health condition at
all) should consult with their physician
before using red light therapy.
