3 experts · Moderate agreementWhat the gurus are saying
This serum's 3% hyaluronic acid concentration is unusually high, making it thick in the bottle but smooth on skin. Both gurus appreciated the hydration and ceramides for the moisture barrier, though they weren't convinced they'd repurchase, particularly if they already use other hyaluronic acid products. The fragrance-free formula includes some stabilizing alcohol, which didn't bother those who tried it.
