Overview
A Rodan + Fields serum listed for all skin types, built around alkyl benzoate, peptides and vitamin A, with an aloe scent. Attribute data for this listing is limited, covering only ingredient, skin type and scent details rather than a full spec sheet.

With 385 ratings at 4.4 and 60 units bought in the past month, it shows steady ongoing demand despite thin listing detail.
