I have long been a proponent of estrogen replacement in the menopause. The evidence for positive estrogen effects, especially on the brain, has been scientifically proven for many years.
The following is from Longevity Magazine:
"There currently are 53 supercentenarians – people age 110 years and over, alive today; and 51 of them are female. Ben Dulken, from Stanford University (California, USA), and colleagues explored the potential underlying reasons why no other demographic factor comes remotely close to sex in predicting the likelihood of achieving such an advanced age. With consideration for current knowledge about stem cell behavior and sex, the researchers submit that there are key differences in regenerative decline between men and women: particularly involving the sex hormones estrogen and testosterone in modifying lifespan. Previous studies report that estrogen has direct effects on stem cell populations in female mice, from increasing the number of blood stem cells to enhancing the regenerative capacity of brain stem cells. Further, other recent studies suggest that estrogen supplementation may increase the lifespan of male mice. Observing that: “Longevity differs between sexes, with females being longer-lived in most mammals, including humans. One hallmark of aging is the functional decline of stem cells,” the authors consider that: “a key question is whether the aging of stem cells differs between males and females and whether this has consequences for disease and lifespan.”
Estrogen replacement in the menopause shows 70% less deaths from all diseases compared to non-estrogen users. And if a bio-identical estrogen is used that contains both estradiol and estriol, studies now show a 20% less incidence of breast cancer.
Observing that estrogen supplementation may increase the lifespan of male mice, I started myself on estrogen - however, I had to stop because too many men were looking at my breasts.

First, the answer is yes, retinol can make wrinkles worse, especially when you first start using it. What is happening is a drying effect, and one can get epidermal sliding from separation from the dermis. But this is temporary, and will eventually end up tightening the skin around the eyelids, provided you are using a potent retinol preparation.
