Citrus-scented serum absorbs instantly, evens skin tone – moisturizer recommended post-use.

Fast-absorbing vitamin C serum brightens dull skin effectively. Fragrant formula requires moisturizer after application for optimal hydration.

This review is from Amazon.com for product:

Eight Saints Vitamin C Serum For Face, Anti Aging Facial Serum, Hyaluronic Acid, Vitamin E, Organic Aloe Vera and Jojoba Oil, Hydrating & Brightening Serum for Dark Spots, Fine Lines and Wrinkles, 1oz

I love the smell of this serum. It literally soaks into my skin so when I’m done applying it there is nothing left over.

Overall, it has helped brighten and even my complexion.

I just recommend a moisturizer after use.

Vitamin Basics & Tips

Vitamin C serums like this one leverage L-ascorbic acid, a potent antioxidant that neutralizes free radicals caused by UV exposure and pollution. Its ability to inhibit melanin production explains the reported "brightening" effect, as it reduces dark spots and promotes an even skin tone. The serum’s rapid absorption suggests a water-based formulation, which avoids the greasy residue common in oil-based products.

Pairing vitamin C with moisturizer is scientifically sound: antioxidants work best when followed by hydrating agents to reinforce the skin barrier. For daytime use, vitamin C enhances sunscreen efficacy by combating residual oxidative stress. Note that stability matters – opaque packaging and airtight pumps (implied by the reviewer’s "nothing left over" remark) prevent oxidation, ensuring potency.

While not mentioned in the review, combining vitamin C with ferulic acid or vitamin E can amplify its benefits. Users with sensitive skin should gradually introduce such serums to avoid irritation, though the absence of residue suggests this formula is non-comedogenic.
