Sodium Hyaluronate is generally a lower-concern and potentially helpful hydration ingredient for seborrheic dermatitis. It attracts water and conditions the skin, which may support comfort when dryness is present, but it does not treat the underlying condition.

A hydrating serum can still sting if it contains fragrance, strong actives or an unsuitable preservative system. The checked sources provide no yeast-specific finding that changes the rating. Keep using the product only while the complete formula remains comfortable.
