Oyster mushroom hydrates the skin

If women eat 50 grams of oyster mushroom every day, their skin will be better hydrated. Supplementing with 20-25 milligrams of ergothioneine per day may have the same effect.

Study
Researchers from Japan's Hokuto Corporation gave 39 healthy women 21 tablets of dried oyster mushroom every day for 12 weeks. Each tablet weighed 240 milligrams.

Fresh oyster mushroom consists of 90 percent water. [IOP Conf. Series: Earth and Environmental Science 411 (2020) 012007.] If the researchers had used fresh oyster mushroom, they would have given the women about 50 grams of oyster mushroom every day.

A control group of 38 women received a placebo.

Results
Supplementation with dried oyster mushroom increased the amount of moisture in the skin of the test subjects. The skin therefore became less dry. As a result, wrinkles reduced and skin texture improved a little.

Mechanism
The researchers suspect that the amino acid ergothioneine causes at least some of the measured effects. During the experiment, the concentration of that amino acid in the blood of the subjects in the experimental group increased by a factor of 4.7.

The effect of supplementation was greater when the researchers only looked at subjects who had little ergothioneine in their blood before supplementation started. You can see this in the figure above.

The dried oyster mushroom tablets provided approximately 20-25 milligrams of ergothioneine daily. If ergothioneine is indeed 'the' active substance in oyster mushroom, then supplementation with the free amino acid probably has the same effect. Every online supplement store has products that contain 5-10 milligrams of ergothioneine per capsule.
