Overview
A gel serum built around hyaluronic acid and lactic acid, formulated for all skin types. Eight Saints packages it as a daily hydration step rather than a targeted treatment, with no fragrance or oil claims listed in the spec sheet.
Amazon's own spec sheet for this listing is sparse: item form, skin type and the two headline actives are essentially all that's published. That leaves texture, scent and packaging size undocumented, so buyers are working from the ingredient list more than a full spec.
- Gel item form
- Hyaluronic acid and lactic acid actives
- Marketed for all skin types
- 172 rated reviews on Amazon
Who it's for
Suits someone who wants a simple two-ingredient hydration approach, hyaluronic acid plus a mild AHA, without wading through a long ingredient deck. Not the pick for anyone who needs to confirm size, packaging or full ingredient list before buying, since none of that is listed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- Simple two-active formula
- Gel texture suits all skin types
- Rated 4.4 across 172 reviews
- Bottle size not listed
- Full ingredient list not published
Performance notes
Hyaluronic acid draws moisture into the skin's surface layer while lactic acid, a mild alpha hydroxy acid, provides gentle exfoliation. Paired in a gel base, that combination is a common formula for hydrating without the heavier feel of a cream.
