Short answer: the Klairs Freshly Juiced Vitamin Drop is a gentle, low-percentage vitamin C serum (5% vitamin C, listed as ascorbic acid) for dull-looking skin and uneven-looking tone, made as a beginner-friendly way to start vitamin C. One thing to know up front: it is not fragrance-free. It contains citrus extracts and essential oils, including orange oil and lavender oil, plus limonene. Here are the questions people ask most before trying it.
What It Is, in Plain Terms
The Freshly Juiced Vitamin Drop is Klairs' gentle vitamin C serum. Instead of starting at a high strength, it uses 5% vitamin C so people who are new to vitamin C, or who find stronger formulas too much, can build a glow-focused step into their routine. Alongside ascorbic acid, the ingredient list includes sodium ascorbyl phosphate, centella asiatica extract, sodium hyaluronate and a range of botanical extracts, including citrus junos and grapefruit extracts. It is a cosmetic brightening serum that helps the look of dullness and uneven tone over time, not an exfoliating product or a medical dark-spot product.
Who It Suits
- Vitamin C beginners who want a lower-strength place to start.
- Dull or tired-looking skin that wants a brighter-looking, more radiant finish.
- Uneven-looking tone in a simple, consistent routine with daily sunscreen.
- Normal, combination and oily skin that likes a lightweight dropper serum.
- Not a fit if you avoid fragrance or essential oils: this formula contains orange oil, lavender oil and limonene.
How to Use It
After cleansing and toner, apply a few drops and gently spread and pat them over your face, then follow with moisturizer. If your skin is new to vitamin C, start with 1 to 2 drops, or mix them into your moisturizer, a few times a week and build up slowly; the product page suggests 3 to 4 drops once your skin is comfortable. It can be used morning or night, up to twice a day. In the morning, always finish with sunscreen.
Klairs Freshly Juiced Vitamin Drop FAQ
What is the Klairs Freshly Juiced Vitamin Drop?
It is a gentle 5% vitamin C serum designed for beginner-friendly and sensitive-skin brightening routines. Ascorbic acid is the main vitamin C on the ingredient list, supported by sodium ascorbyl phosphate, centella asiatica extract, sodium hyaluronate and botanical extracts. It is used to help skin look brighter, more radiant and more even-looking with consistent use. It comes in a 35 mL dropper bottle and is meant to sit after toner and before moisturizer.
Does the Freshly Juiced Vitamin Drop contain fragrance or essential oils?
Yes, and it is not fragrance-free. The formula contains citrus extracts and essential oils, including orange oil and lavender oil, as well as limonene, so it has a light citrus scent. If you avoid fragrance or essential oils, choose a different product; our guide to which Klairs products have no added fragrance lists the options that do not contain them.
Is it gentle enough for sensitive skin or vitamin C beginners?
It is positioned as a gentle, lower-percentage vitamin C for beginners and sensitive-skin routines, which is why many people use it as their first vitamin C serum. Because it contains essential oils and vitamin C, start slowly if your skin is reactive: patch test, use 1 to 2 drops, and increase only if your skin stays comfortable. We explain why a lower strength can make sense in is low-percentage vitamin C worth it for sensitive skin.
Has it been tested on skin?
Yes. The formula was tested by P&K Skin Research Center for primary irritation, primary irritation on sensitive skin, cumulative irritation and sensitization, and non-comedogenicity, and its antioxidant activity was tested with a DPPH assay. These are tolerance and lab tests rather than results showing how your skin will look, and individual skin varies, so patch testing is still the best way to see how your own skin responds.
Why does it feel warm when I apply it?
Some people notice a brief warm feeling when they apply vitamin C. Start with 1 to 2 drops, or mix them into your moisturizer, and increase slowly as your skin gets used to it. A mild, short-lived warmth can be normal, but if it stings or burns, rinse it off and stop using it.
My serum turned yellow or darker. Is it still okay to use?
Vitamin C reacts with air, light and heat, so the color can deepen over time; a gradual change to yellow is expected with this kind of formula. For the best vitamin C effect, use it within 6 months of opening (the period after opening is 12 months). If it has turned a deep orange, replace it. Our guide has my vitamin C serum oxidized? explains what color, smell and packaging can tell you.
How should I store it?
Keep the cap tightly closed after every use and store the bottle somewhere cool and dark, away from direct sunlight, steamy bathrooms and heat. Exposure to air, light and warmth is what makes vitamin C change color faster. Buying a size you will finish within a few months and using it daily also helps you use it at its freshest.
Should I use it in the morning or at night?
Either works, and it can be used up to twice a day. Apply it after cleansing and toner, before moisturizer. Many people like it at night, but if you use it in the morning, always finish with sunscreen; daily sun protection matters for the look of uneven tone more than any single serum.
Can I use it with retinol, AHA or BHA?
We do not recommend layering it in the same routine with exfoliating or strong active products such as retinol, AHA, BHA or high-concentration vitamin C, because the combination may irritate your skin. If you use those, try the Vitamin Drop in the morning and your other active at night, or alternate nights, and keep the rest of your routine simple and moisturizing.
What can I pair it with?
It pairs naturally with the Freshly Juiced Vitamin E Mask as a glow-and-moisture routine, and with a simple moisturizer. You can also use it with the EGF Blue Youth Activating Drop: apply the EGF Blue drop first, then the Vitamin Drop. For extra-sensitive skin, mixing a few drops of the Vitamin Drop into a serum or moisturizer is an easy way to ease in.
Will it feel oily, and how long before I notice a difference?
It has a light, slightly oil-like slip that absorbs; oily skin types often prefer it at night or with fewer drops. Brightening-focused routines usually take several weeks of consistent use, together with daily sunscreen, before skin looks more radiant and even. Expect gradual, cosmetic changes rather than overnight results.
What size is it, and how much does it cost?
The Freshly Juiced Vitamin Drop comes in a 35 mL dropper bottle, listed at $16.10 on klairs.com at the time of writing. It is a vegan formula, Dear, Klairs is a cruelty-free brand, and it is made in Korea. Check current pricing and details on the product page.
