NEW YORK — For years, cosmetic chemists have warned consumers that the skin whitening drugs they use to improve skin tone can make the skin appear darker.
Now, the FDA is recommending that they only use whitening creams, which do not contain any whitening agents.
And they should only use them on the face.
The FDA’s guidelines do not specify which skin type should receive whitening treatment, but they state that all people should be treated equally.
The agency also advises against using products containing a product called tretinoin, which is often marketed as an anti-aging product.
Whitening creamps have long been controversial because they are highly toxic.
In 2013, a lawsuit filed by the FDA against a cosmetic chemist and a cosmetics company was settled for $1.6 million.
In a statement, the company said it is “extremely disappointed” with the FDA’s decision.
“It’s important to note that we have been working with the agency to develop a regulatory framework that is more aligned with our customers’ needs,” the statement said.
“While we believe that all Americans should receive effective skin care and whitening treatments, we understand that some patients have a unique need that differs from the average consumer.”
Whitening treatments have been a popular way for dermatologists to boost skin’s youthful appearance.
They can be used to brighten dark patches, and to treat sensitive skin, according to the American Academy of Dermatology.
Whitening products have long provided an alternative to chemical-laden products that cause irritation, and they have been popular among celebrities.
They have been marketed as “skin brighteners” that help brighten skin and help to prevent the appearance of wrinkles.
But dermatologists have warned against using skin whiteners on sensitive skin because they can cause allergic reactions, especially to certain types of ingredients.
A few years ago, a group of doctors led by Dr. Joseph A. Reuter at the University of Pittsburgh wrote a report on the dangers of skin whitener use in which they suggested patients be cautious about using them on sensitive, acne-prone skin.
The report concluded that the risk of skin cancer is highest when skin whitners are used for the first time and that using skin lightening creaks can cause more severe skin reactions, such as breakouts.
Dr. Reuters recommendation to avoid using skin creams or sunscreens to lighten skin was backed up by research from the University at Buffalo.
The group concluded that skin lighteners should not be used for less than 2 weeks, because of their increased sensitivity to the sun.
They also said that they are not safe for use on patients who are allergic to chemicals, and should not have a high percentage of their total daily dose applied to the face or body.
A new report released Tuesday by the Cosmetic Dermatologist Group, an industry group, found that skin whiters are becoming more popular, and that many consumers are taking them as a last resort when they can’t tolerate conventional treatments.
The report said that the FDA guidelines do apply to the use of products containing the tretinosin and glycolic acid, which have been the focus of controversy.
But the report found that the industry had begun to shift away from using the products in the past two years.
