Freshly Juiced Vitamin Charging Serum

Product Description

Dear, Klairs Freshly Juiced Vitamin Charging Serum is a lightweight, fast-absorbing brightening serum built around a Dual Brightening Complex of 10% 3-O-Ethyl Ascorbic Acid (a stable Vitamin C derivative) and Niacinamide. At a gentle pH of around 5.9, it targets dullness, uneven tone, dark spots, and early fine lines without the sting, oxidation, or flaking that pure Vitamin C can cause โ€” making it a friendly entry point for sensitive skin and Vitamin C beginners.

Dual Brightening Complex

10% 3-O-Ethyl Ascorbic Acid and Niacinamide work together to brighten tone, fade dark spots, and boost radiance.

๐Ÿงฌ

Gentle on Sensitive Skin

A higher pH (~5.9) than pure Vitamin C means little to no sting, flaking, or flushing for most users.

๐ŸŒฟ

5 Antioxidants In One

Vitamins C, E, B3 and B5 plus madecassoside (Centella) help defend against daily environmental stress.

โšก

Quick AM Routine

One pump absorbs in seconds and layers smoothly under sunscreen and makeup without pilling.

๐Ÿ›ก๏ธ Safety & Compatibility

โœ…
Pregnancy & Breastfeeding

Free of retinoids, salicylic acid, hydroquinone, and chemical sunscreens. Vitamin C derivative and niacinamide are generally considered pregnancy-friendly โ€” but always confirm with your doctor.

โš ๏ธ
Fungal Acne (Malassezia)

Contains linolenic acid (a fatty acid) and citrus fruit extracts, which can feed malassezia. Not recommended if you are actively managing fungal acne.

๐Ÿค
Vitamin C + Niacinamide

Both actives are already combined in one stable formula, so there is no need to worry about layering them separately.

๐Ÿ‹
Citrus Extracts

Lemon, mandarin, and grapefruit extracts add antioxidants but can irritate very reactive skin. A patch test is recommended first.

โ˜€๏ธ
Daytime Friendly

Antioxidants help support your sunscreen's defense. Always follow with a broad-spectrum SPF in the morning.

๐Ÿšซ
Alcohol-Free

No drying SD or denatured alcohol, so it is comfortable for dehydrated and barrier-compromised skin.

๐Ÿ”ฌ Ingredient Breakdown

๐ŸŠ 3-O-Ethyl Ascorbic Acid 10% Proven

A stable, water-and-oil-soluble Vitamin C derivative and the star active. It brightens, helps fade pigmentation, and acts as an antioxidant without the rapid oxidation of pure ascorbic acid.

  • Stability: Far more shelf-stable than pure L-ascorbic acid, so it stays effective longer.
  • Conversion: Manufacturer data indicates it converts to pure Vitamin C in the skin, with a high ascorbic acid content (~86%).
  • Evidence: In-vivo clinical data shows ethyl ascorbic acid can improve skin tone and brightness.
โš ๏ธ
A brief warm sensation may be felt on application as the Vitamin C absorbs โ€” this is normal and fades quickly.

๐ŸŒŸ Niacinamide Vitamin B3 Proven

A multi-tasking skincare superstar that partners with the Vitamin C derivative to even tone, refine texture, and strengthen the skin barrier.

  • Brightening: Helps fade dark spots and improve overall radiance.
  • Barrier: Boosts ceramide synthesis for a stronger barrier and better hydration.
  • Oil & pores: Clinically supported for reducing the look of pores and balancing oil.
โœ…
The old "you can't mix Vitamin C and niacinamide" myth has been debunked โ€” here they are formulated together intentionally.

๐Ÿ’ง Sodium Hyaluronate Hyaluronic Acid Proven

The salt form of hyaluronic acid and a key humectant that plumps and hydrates, balancing the brightening actives so the formula stays comfortable.

  • Hydration: Can hold many times its weight in water for a plumper look.
  • Brand testing: Klairs reports a 20%+ improvement in skin hydration after two weeks of use.

๐ŸŒฟ Madecassoside Centella Asiatica Promising

A purified active from Centella Asiatica (Gotu Kola) that soothes, calms, and supports the skin while the actives work.

  • Soothing: Well-established skin-calming and antioxidant activity.
  • Tone: Research suggests it may help inhibit UV-induced melanin, supporting an even tone.

๐Ÿงช Panthenol Pro-Vitamin B5 Proven

A humectant and skin-soother that moisturizes and helps reduce irritation from more active ingredients.

  • Moisture: Attracts and holds water, keeping skin soft and supple.
  • Comfort: Anti-inflammatory and barrier-supporting, ideal for sensitive skin.

๐Ÿ›ก๏ธ Tocopherol Vitamin E Proven

A fat-soluble antioxidant that works in synergy with Vitamin C to boost antioxidant and photoprotective benefits.

  • Synergy: Vitamin C and Vitamin E together provide stronger antioxidant defense than either alone.
  • Protection: Offers meaningful protection against UVB-related free-radical damage.

โ“ Frequently Asked Questions

It is generally considered pregnancy- and breastfeeding-friendly. It contains no retinoids, salicylic acid, hydroquinone, or chemical sunscreens, and its main actives โ€” a Vitamin C derivative and niacinamide โ€” are widely regarded as safe during pregnancy. As always, confirm with your own doctor or OB-GYN before adding any product during pregnancy.

No. The formula contains linolenic acid (a fatty acid) and citrus fruit extracts, which can potentially feed the malassezia yeast linked to fungal acne. If you are actively managing fungal acne, this serum is best avoided.

It already pairs a Vitamin C derivative with niacinamide, so there is no conflict between those. It layers well in the morning and works nicely alongside retinol used at night. If you also use strong AHAs or BHAs, alternate days or times to avoid over-exfoliation, since this gentle derivative is forgiving but layering many actives can still irritate.

It is formulated for all skin types and is especially well-suited to sensitive skin and Vitamin C beginners, thanks to its gentle pH and soothing actives. Oily and combination skin love the lightweight finish, while dry skin should layer a richer moisturizer on top.

Brand testing reports brighter, more revitalized skin in about 14 days, with a 20%+ improvement in hydration after two weeks. Dark spots and uneven tone typically soften over 4 to 8 weeks of consistent daily use, with firmness and smoothness improving over 8 to 12 weeks.

Use it after cleansing and toning, while skin is still slightly damp, and before your moisturizer. It is ideal in the morning for its antioxidant boost โ€” just remember to finish with a broad-spectrum sunscreen.

It rates low on the comedogenic scale (around 1 out of 5). The formula is water-based, oil-free, and non-sticky, so it is unlikely to clog pores for most people. Note, however, that low comedogenicity is not the same as fungal-acne safe โ€” see the malassezia question above.

The period after opening (PAO) is 6 months, so aim to use it within six months of first opening. Unopened, it carries roughly a 36-month shelf life from the manufacture date. Storing it cool and away from sunlight helps keep the Vitamin C effective.

โ˜…โ˜…โ˜…โ˜…โ˜†
4.5 out of 5

Verdict: Dear, Klairs Freshly Juiced Vitamin Charging Serum is a standout entry-level Vitamin C serum. Its stable 10% 3-O-Ethyl Ascorbic Acid and niacinamide brighten and even tone without the sting, oxidation, or flaking of pure Vitamin C, making it ideal for sensitive skin and Vitamin C beginners. The trade-offs are that it is not fungal-acne safe, the citrus extracts will not suit everyone, and the 30ml bottle feels small for the price. For gentle, reliable everyday brightening, it is an easy recommendation.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging ยซpromisesยป it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
