The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other anti-aging skincare: serums, night creams, facial peels, wrinkle patches and anti-aging devices we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
['This Eight Saints serum focuses on two well-established skincare ingredients. Hyaluronic acid is a humectant that binds water to the skin and may help support the appearance of fullness and hydration. Lactic acid is a gentler alpha hydroxy acid compared to glycolic, which makes it a common choice for people new to chemical exfoliation or those whose skin does not tolerate stronger acids well.', 'The gel form and all-skin-types listing make this a broadly accessible option. It positions itself at the more affordable end of the Eight Saints lineup at $32, sitting $2 below one sibling SKU and $7 below another. For someone who wants a dual-active serum without many layers to the routine, the ingredient pairing keeps things simple.', 'With 172 reviews and a 4.4-star average, buyer reception is positive. That review volume is enough to suggest the rating reflects a real pattern rather than a handful of early opinions. The absence of any listed benefits or targeted concerns in the product data means the positioning is broad, which matches its all-skin-types claim.']

Performance notes
Hyaluronic acid functions as a humectant that may help the skin look plumper and feel more comfortable. Lactic acid as a gentle AHA may support a smoother-looking surface and a more even tone over time with consistent use. The combination is a reasonable two-step approach to the look of texture and hydration from a single product, without the potential complexity that vitamin C or retinoids can introduce.

Frequently asked questions
Is lactic acid safe for sensitive skin?
Lactic acid is one of the milder alpha hydroxy acids and is often recommended as a starting point for people who find glycolic acid too strong. That said, sensitivity varies by individual, concentration, and how often a product is used. If you have reactive skin, patch-testing and starting with less frequent applications is a sensible approach.
What does hyaluronic acid actually do in a serum?
Hyaluronic acid is a humectant, which means it draws moisture toward the skin from the environment and deeper skin layers. In a serum, it may support the appearance of plumper, more hydrated skin and reduce the look of fine lines that come from dehydration rather than structural aging. It works best when the skin is slightly damp and a moisturizer is applied on top to seal the hydration in.
How does this serum compare to the Eight Saints option with vitamin C?
This version includes hyaluronic acid and lactic acid without vitamin C, keeping the formula simpler and potentially less irritating for some users. The Eight Saints serum with vitamin C adds a brightening antioxidant to the mix but costs $7 more. If your main goals are hydration and texture improvement, this SKU covers those. If you also want to target the appearance of dark spots or dullness, the vitamin C version may be a better fit.
