Tecnu Rash Relief Spray can be used on a sunburn.

Yes. However, please use caution. Spray onto your fingers first, then apply to your face (be sure to avoid eyes & mouth). Thoroughly rinse your hands after.

Tecnu Rash Relief Spray has never been color/damage-tested on hair, so we can't say with certainty that it won't damage the hair. The bigger cause for concern is that it may run down into the eyes. We recommend testing an inconspicuous piece of hair first. Use care to avoid getting product in or around your eyes.

None of our medications are specifically indicated for use on shingles. Consult your doctor for proper treatment.

Tecnu Rash Relief Spray contains essential oils and alcohol, both of which may sting/burn sensitive areas such as the genitals.

Tecnu Rash Relief Spray has not been tested for use on animals, please consult your veterinarian.

It is always a good idea to wash the affected area, whenever practical, before using Tecnu Rash Relief Spray to keep the area clean. It is also best to leave the affected area uncovered so that it can breathe; if you must apply a bandage, be sure that it is loose.
