Hyaluronic Acid for Dry Skin
B Good Evidence At least one randomized trial supports this, with mostly consistent results.Multiple RCTs found oral hyaluronic acid (120-240 mg/day) significantly improved skin moisture and reduced transepidermal water loss (TEWL) over 4-8 weeks compared to placebo.
The Bottom Line
Multiple RCTs found oral hyaluronic acid (120-240 mg/day) significantly improved skin moisture and reduced transepidermal water loss (TEWL) over 4-8 weeks compared to placebo.
