For dullness and texture
Limited evidenceThe foundational study randomized 20 women to 6 hydradermabrasion sessions versus manual serum application and found improved skin quality clinically and histologically, including increased epidermal thickness and skin antioxidant levels, in the device group only. That is a single 20-person trial from 2008; it supports a real short-term smoothness and radiance effect, nothing more durable, and results fade without repeat visits.
Only small, short, or lower-quality studies exist. Treat marketing claims about this use with caution.
