A drug used to treat wrinkles and acne is being linked to people looking younger in a study published online in the journal Science Translational Medicine.
The study, which was funded by the U.S. National Institutes of Health, involved 6,000 adults and included more than 5,000 women.
It found that people who took retinols at high doses in the first few weeks of pregnancy appeared to have a more youthful appearance compared with people who received the placebo.
Retinol products include Retinac and Retinex.
It’s a small study, and it’s hard to draw conclusions about whether retinoids could help prevent premature skin aging, said Jennifer T. Korn, an associate professor of dermatology at New York University School of Medicine.
But she noted that retinolemic agents are already being tested in people and in clinical trials.
In fact, the FDA has approved Retinapr for people who have wrinkles and/or dryness caused by allergies.
But it has not approved Retinalis, a retinoid used to help people who are diabetic or have other health problems.
Retinoids also have a wide range of uses.
They can treat acne, psoriasis and eczema, and are generally thought to improve blood flow in the skin.
They also help prevent the formation of scar tissue and can reduce redness.
Some people who take retinolic acid may not need a retinalner to achieve these results.
But some people are more sensitive to the drug, and its effects can also be damaging, said Elizabeth A. Gannon, a professor of medicine at the University of Colorado, Boulder, who has been studying retinosteroids.
A few studies have shown that retinyl palmitate, a type of retinoesterone, is also helpful for the skin, said Dr. Ayelet L. Siegel, a clinical professor of ophthalmology at Columbia University.
However, Siegel cautioned that there’s no research yet to show that retinoic acid or retinotecan improve wrinkles.
People who are retinoseptitcans intolerant, such as those with keratoconus or psorias sanguinis, should also avoid retinone-containing products, which are considered risky, she said.
Siegel said the data presented in the study showed that retinal acid has the potential to be an effective treatment for wrinkles and dryness, but that further research is needed to understand how it affects the other signs and symptoms that people experience.
