Dr. Doris Day, a dermatologist at New York University, said the results of the study were not a real surprise.
Vitamin A derivatives, like retinyl palmitate are found in many over the counter drugs available in the U.S., many of which work similarly and are inexpensive.
"There are plenty of comparable products here. No one has to go to England," Day said.
Day said Neutrogena Healthy Skin Anti-Wrinkle Cream, which contains retinol and Olay Professional Pro-X Deep Wrinkle Treatment, which contains retinyl propionate would likely yield similar results in users.
The Neutrogena product sells for around $14 and the Olay cream for around $40 on drugstore.com.
"Vitamin A is one of most tried-and-true and studied ingredients. I recommend it everyone who can tolerate it," she said.
"The sun accelerates the skin's natural aging process. Vitamin A minimizes the damage. It helps skin cells turn over in more normal healthy way," she added.
Some cosmetics experts, however, are skeptical of the Manchester study because Boots funded the research.
"Studies are great and vital to understanding how skin works and what helps skin work better, but not all studies are created equal and study is not definitive of anything, and a study paid for by the company selling the product is ALWAYS circumspect. It's not that the study may not be valid, but the bias is present from the beginning and that must always be taken into consideration," wrote Paula Begoun, author of "Don't Go to the Cosmetics Counter Without Me," in an e-mail.
