Floral water does not cure prickly heat. Flower water is a summer hygiene product, which is a perfumed product made with flower oil as the main fragrance, together with alcohol. Flower water is not a medicine and has no role in treating diseases, so the statement that flower water can cure prickly heat is not true. Prickly heat, also known as sweat rash and corn rash, is considered to be related to long-term exposure to high temperatures and problems with sweating of the skin, such as not being able to evaporate or discharge in a timely manner and gathering in the sweat ducts. It leads to the appearance of pinpoint-sized pimples and papules on the skin with itching. Treatments for prickly heat mainly include topical medications and oral medications, for example, topical glycerite lotion can relieve itching and eliminate redness and swelling of the skin. Topical tretinoin cream can control skin inflammation and reduce itching. If itching is obvious, antihistamines can be given systemically, such as loratadine and chlorpheniramine, which can relieve inflammation and treat skin damage. There are more brands of floral water on the market, and the ingredients inside are complex and varied, so if your skin is sensitive, or you are allergic to the substances inside the floral water, it may cause an allergic reaction. Not only can it not treat the disease, but it may also aggravate the patient’s symptoms. Serious skin reactions, such as pimples, pustules, recurrent attacks or gradual aggravation, it is recommended to go to the dermatology department of a regular hospital, under the guidance of specialists, to avoid blind self-medication, so as not to cause adverse consequences.
