Salma Hayek is known for her radiant skin so it wasn't surprising when the Latin beauty introduced her own line of skincare products. The caffeine on the ingredients list, however, raised a few eyebrows.
Do they work?
"Caffeine dehydrates fat cells and therefore can make the skin feel smoother," explains Dr. Len Lopez, a nutrition and fitness expert and author of To Burn or Not to Burn: Fat is the Question. "[Caffeine] also claims to tighten skin while applied and reduces dark circles." Preliminary research also shows that caffeine may help protect against cellular damage caused by sun exposure. The only issue, Dr. Lopez says, is that we don't know how much caffeine can actually be absorbed through the skin. More research is necessary before coming to any hard conclusions.
Are they safe?
"It can't hurt," Dr Brar says, so she gives the okay to try it.
Final verdict: Try it.
