Studies have confirmed that hormonal changes have a huge impact on skin health and beauty. In women approaching menopause, the decline in estrogen levels is the primary cause of skin issues.

As a result, using a mild estrogen like estriol for sagging skin is an extremely effective way to slow down aging, restore elasticity, and reduce wrinkles!

For example, one study looked into the effects of topical estriol and estradiol in women with skin aging signs. After 6 weeks of treatment, all women noticed a significant improvement in skin elasticity and firmness, as well as a huge decrease in wrinkle depth and pore size.

No systemic hormonal side effects were reported, meaning that skincare products with estrogens are both effective AND safe to use for skin support.

Many studies have looked into the effect of topical estrogen products on the aging skin. Here's a quick rundown of the most interesting findings:

• Adverse effects are rare. Moreover, when they actually happen, they're mild at most. For example, one study noted temporary breast tenderness in three participants. One participant experienced local redness in the area treated with the estrogen cream.
• No systemic side effects were reported in most studies.
• There is a possibility of systemic benefits. In one study, topical application of estrogens on the forearm resulted in noticeable improvements on the subject's cheeks.

Aside from those already mentioned, some studies reported a few extra side effects related to estriol usage specifically. These include mild breast pain and localized discomfort. One study even suggested that a decrease in breast milk production is possible.

Another study pointed out the potential of estriol in helping with menopause symptoms. For instance, there's evidence suggesting that estriol may help with vaginal dryness, hot flashes, and even reduce the risk or urinary tract infections (UTIs). Last but not least, estriol appears to be beneficial for bone density and strength.

The effects of estriol on cardiac risk factors has yet to be clearly established. Nonetheless, preliminary data has found that estriol doesn't seem to cause hypertension—and that's a good start already.

Although estriol seems to be safer to use than other estrogens like estradiol and estrone, using it in high doses may have a stimulatory effect on both endometrial and breast tissue.

Estrogens like estriol help in the production of collagen. Collagen is the protein that gives the skin its firmness and structure. With aging, collagen production goes down, leading to wrinkles and sagging.

Restoring hormonal balance can help the body produce more collagen. In fact, studies have found a strong correlation between estrogen deficiency and collagen loss during menopause.

Using estriol cream has many advantages, including:

• Estriol can be sourced naturally from plants
• Estriol does not need the counterbalancing effect of progesterone
• Estriol doesn't have an invasive effect. This means that topical applications of estriol remain and work on the skin, rather than entering the bloodstream and acting systemically.
• There's evidence that estriol may counteract the unwanted effects of using estradiol
