326 owner reviews, fewer than most models here
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
['Eight Saints positions this serum around three actives that appear regularly in dermatology-informed skincare discussions. Hyaluronic acid is a humectant widely used to support the appearance of plump, hydrated skin. Lactic acid is a gentle alpha hydroxy acid that may help with the look of uneven texture and dull tone. Vitamin C, as an antioxidant, is often used to target the appearance of dark spots and support a brighter-looking complexion.', 'The gel form means a lighter, fast-absorbing texture compared to creams or oil-based serums. That usually works well under moisturizer or sunscreen and suits people who dislike heavy or greasy layers. No skin type is specified in the available data, but gel serums are generally compatible with a wide range of skin types, including oilier ones.', 'At $39 and with 326 reviews averaging 4.3 stars, this sits at a solid spot in the mid-range market. The review count is large enough to suggest a consistent buying audience rather than a fluke pattern, and the 4.3 average reflects generally positive but not universal satisfaction.']

Performance notes
Hyaluronic acid draws moisture to the surface and may help the skin look fuller and more hydrated. Lactic acid works at the surface level to support a smoother texture and more even tone over time. Vitamin C in a serum context is most recognized for targeting the appearance of uneven pigmentation and supporting a brighter look. The gel base keeps the formula lightweight, which helps these actives absorb rather than sit on the surface.
What buyers say
326 ratings averaging 4.3 stars reflects a solid consensus among buyers, with the majority reporting positive outcomes. A 4.3 average at this volume typically means a minority of users experienced issues, whether with results, scent, or texture. No monthly purchase volume data is available.

Frequently asked questions
Can I use this serum if I have sensitive skin?
The formula contains lactic acid and vitamin C, both of which can cause temporary redness or stinging in reactive skin types. The listing does not specify sensitive-skin compatibility. If you have reactive skin, start with a small patch test and consider spacing out use to every other day until your skin adjusts.
Does combining vitamin C and lactic acid in one serum cause problems?
Both ingredients work at a lower pH, so they are technically compatible in the same formula. The practical concern is that using multiple actives together increases the chance of irritation for some people, especially if the skin is new to acids. If you experience redness or tightness, try using the serum less frequently and build up gradually.
Is $39 reasonable for a serum with these ingredients?
For a three-active gel serum with hyaluronic acid, lactic acid, and vitamin C, $39 sits in the lower-to-mid range of the market. Many comparable multi-active serums from specialty brands run $50 and above, so the price is competitive. Whether the specific concentrations justify the cost is something the ingredient list and your own skin response will determine over time.
