  • Morning and night

What it is

Gleamin's most concentrated face formula, from the brand that builds skincare for dark spots with melanin-rich skin in mind. A daily vitamin C serum built for people who want to see their tone look brighter and more even without juggling five different bottles.

What it does

Brightens tone, evens the look of dark spots and post-breakout marks, and smooths texture, with 15% vitamin C doing the heavy lifting. Bakuchiol adds a gentle retinol-alternative smoothing effect, while niacinamide and hyaluronic acid keep the formula balanced and comfortable.

Who it's for

Skin prone to dark spots, dullness, or rough-feeling skin. Anyone who wants one serum that does a lot; sensitive skin starts once a day or every other day.

How to use

How much: One to two pumps for face and neck.

1. After cleansing, dispense 1 to 2 pumps.
2. Smooth evenly over your face and neck.
3. Follow with moisturizer. In the morning, finish with a broad-spectrum sunscreen.
4. Use morning and night. If your skin is sensitive, start once a day or every other day.

Where it fits: After cleansing, before moisturizer. Pair with the Vitamin C Clay Mask for the brand's core brightening duo.

Inside the formula

15% vitamin C (3-O-ethyl ascorbic acid + sodium ascorbyl phosphate)

Two stable forms of vitamin C for a brighter, more even-looking tone and antioxidant support

4% niacinamide

Vitamin B3, a well-studied ingredient that helps uneven-looking tone look more balanced and supports the skin barrier

Bakuchiol

A plant-based alternative to retinol that helps skin look smoother and more refined

Turmeric

A kitchen classic loved for its glow-boosting reputation; it also gives the mask its sunny color

Hyaluronic acid

Holds moisture in skin so the serum does not dry you out

About the brand

Gleamin

The vitamin C mask that went viral

Gleamin was started by New Zealand founder Jordan Smyth, who struggled with rosacea and spent two years perfecting a mask inspired by homemade turmeric-and-vitamin-C rituals. The result was their Vitamin C Clay Mask, blending Kakadu plum, desert lime, and turmeric: vegan, cruelty-free, dermatologist tested, and comfortable to wear instead of tight and cracky. Now based in Los Angeles, the brand has earned the trust of over a million customers.

We stock Gleamin because their clay mask actually brightens without that tight, cracked-face feeling, and the reviews speak for themselves.

Skincare questions, answered

Where does this go in my routine?

Thinnest to thickest: cleanser, toner, serum, moisturizer, then SPF in the morning. This product's How to use section above tells you its exact step.

When will I see results?

Give it 4 to 6 weeks of consistent use — that's one full skin cycle. Hydration shows up in days; tone and texture take weeks. If your skin reacts badly (stinging, new breakouts that don't settle within a week), stop using it.

I have sensitive skin. Will this irritate me?

Patch test first: a dab behind your ear or along your jawline, wait 24 hours. Fragrance-free formulas are the safest bet for reactive skin — check the highlights on this page.
