18% Vitamin C Serum for Brighter, More Even-Looking Skin
Trendy Blends 18% Vitamin C Serum is made for skin that’s starting to look dull, uneven, or tired. It pairs 18% 3-O Ethyl Ascorbic Acid, a stable form of vitamin C, with niacinamide and hyaluronic acid, then adds aloe and cucumber to keep things calm and comfortable.
It’s fragrance-free, comes in a 1 oz airless pump, and is made for everyday use, including on mature and sensitive skin.
What This Vitamin C Serum Helps With
- Dull, tired-looking skin: Helps bring back a brighter, fresher-looking glow.
- Dark spots and uneven tone: Helps fade the look of dark spots and sun spots over time.
- Fine lines: Supports the look of firmer, smoother skin as part of a daily routine.
- Dryness: Hyaluronic acid and glycerin help skin look plumper and feel hydrated.
- Daily environmental stress: Vitamin C is an antioxidant that helps defend skin against free radicals from UV exposure and pollution.
What’s Inside Our 18% Vitamin C Serum
18% 3-O Ethyl Ascorbic Acid
Our vitamin C is 3-O Ethyl Ascorbic Acid, a stable form of vitamin C. Classic L-ascorbic acid is the most studied form, but it’s fragile and can turn brown soon after opening. 3-O Ethyl Ascorbic Acid is built to hold up much better, so your last pump works like your first.
Niacinamide (Vitamin B3)
Niacinamide helps even out the look of skin tone and supports the skin barrier. It’s a natural partner for vitamin C when dark spots and dullness are your main concerns.
Hyaluronic Acid and Glycerin
These two hydrators draw water into the skin’s surface, so skin looks plumper and smoother and the serum never feels drying.
Aloe and Cucumber
Aloe leaf juice and cucumber fruit extract give the formula a soothing, cooling feel, a thoughtful balance for a high-strength vitamin C you use every day.

Why We Use an Airless Pump
Vitamin C breaks down faster when it’s exposed to air and light. Our airless pump keeps air out of the bottle, so the serum stays fresher from the first pump to the last.
- Less air exposure: Air doesn’t flow back into the bottle after each use.
- Cleaner dispensing: No fingers or droppers dipping into the formula.
- The right amount every time: 1 to 2 pumps covers your face and neck.

How to Use Our Vitamin C Serum
- Cleanse: Start with a freshly cleansed face and pat dry.
- Apply: Press 1 to 2 pumps gently into your face and neck, focusing on areas with uneven tone. Let it absorb for about 30 to 60 seconds.
- Moisturize: Follow with your favorite moisturizer.
- Protect: In the morning, always finish with a broad-spectrum SPF 30 or higher.

Tracy C. –
best Serum by Far
This is a kind of all-in-one serum with all the good buzz ingredients in the skincare world right now (minus snail mucin). They don't list the percentages of the main ingredients so it is hard to know if is 5% or 10% niacinimide and what percent hyaluronic acid is in this though. Aside from that though, I was happy to see that they included aloe leaf juice in here since that is incredibly good for the skin. The ingredients list is recognizable and there are none of those hard to pronounce multi-syllabic ingredients that you have no idea what it is for and where it is sourced from.
