Review a product Dear, Klairs on your skin profile.

«Simple but sufficient» - a strict formulatory charter.

Dear, Klairs was born in 2010 in Seoul by the Wishcompany. Its name is conceived as « a love letter to a girl struggling with her skin »- products are developed based on customer feedback, not industry trends. The brand has reformulated and adjusted its products by listening to users, even modifying its packaging according to feedback received.

01

Strict formulatory charter

All formulas systematically exclude : artificial colors, alcohol, parabens, artificial fragrances. All products are vegan, cruelty-free, made in Korea. Supple Preparation Toner has sold over a million bottles in more than 40 countries.

02

Slogan: «Basic but Ultimate - Gentle but Powerful».»

A precise formulatory philosophy: fewer, better-chosen ingredients at effective concentrations. A 3-storey boutique in Seoul with a tea ceremony waiting list of several weeks - a strong emotional positioning around listening to difficult skins.

Editorial reading

«Dear, Klairs is the K-beauty brand that most closely respects its positioning in the BeautyDecoded data. The «Simple but Sufficient» promise is directly reflected in the scores: 8 out of 12 products have positive or zero sensitive skin scores. But the real reviews reveal two clinically interesting paradoxes: Midnight Blue Sérum (algorithmic anti-aging 76.5 but 4 reviews converge on «no visible results»), and Vitamin C (4/5 in irritating daily use, «incredible» in intermittent use).»

The 6 Dear, Klairs ranges - skin target and key products.

Each range targets a specific skin profile. The Supple Preparation range is available in two versions: with and without fragrance - a clinically significant difference (+1.25 vs. -9.75 in sensitivity).

range Skin target BD key products
Midnight Blue Sensitive, stressed skin, redness, after-sun Calming Cream (9 reviews 5/5) + Youth Activating Drop (4 reviews 3.6/5)
Supple Preparation Universal moisturizing, pH balance, sensitive skin Fragrance-free Toner (4 avis 5/5) + Original Toner + All-over Lotion
Rich Moist Soothing Deep hydration, reactive and dehydrated skin Serum (2 reviews 5/5) + Ampule Mist (1 review 5/5)
Fundamental Light all-purpose care for combination to oily skin Water Gel Cream + Watery Oil Drop + Eye Gel
Freshly Juiced Vitamins C and E, radiance and anti-dark spot Vitamin C Drop (3 opinions 4/5)
Cleaning Double gentle cleansing for all skin types Gentle Black Cleansing Oil (1 review 4/5)

8 products out of 12 with sensitivity score zero or positive.

A direct consequence of the brand's formulatory charter. No BeautyDecoded reviews report any irritation on the Midnight Blue, Supple Preparation, Rich Moist and Fundamental ranges. The two exceptions (Vitamin C and Toner with fragrance) are linked to identifiable formulatory choices.

Supple Preparation Toner Fragrance-free +1,25 Reference for sensitive skin - fragrance / EO / alcohol-free

Vitamin C Freshly Juiced -7,75 Ascorbic acid pH 2.5-3 - intermittent use recommended
Supple Preparation Toner with fragrance -9,75 Fragrance present - contraindicated for hyper-reactive skin

The 12 products analyzed, at a glance.

Sorted by descending BeautyDecoded rating. The catalog is divided into two groups: «basic fragrance-free» products rated 5/5 (Fragrance-Free Toner, Rich Moist, Water Gel) and active anti-aging products rated 3.3-4/5 - perceived efficacy does not always follow formulatory architecture.

★★★★★«Perfect - used as after-sun for 3 weeks in the tropics! No irritation (sun 50+ several times a day of course).»
★★★★★«Magical - this cream soothes the skin, calms redness, moisturizes and penetrates well.»
★★★★★«Comfortable and soft - this cream is soft and comfortable but that's it, it has no particular effect on the skin. It just moisturizes. I only bought it once.»
★★★★★«Very good - the texture is perfect, I can apply make-up afterwards without any problem. Effective moisturizer.»

🔍
Why this paradox? Anti-ageing score 76.5 (high), but 4 opinions converge on the absence of any visible effect. Guaiazulene and centella are anti-inflammatory active ingredients but with a gradual and subtle action - not very noticeable in the short term. The Midnight Blue cream (same range, same active ingredients, richer format) scores 5/5 out of 9 reviews: the difference is the texture and immediate sensation, not the active ingredients.
«Serum Midnight Blue Youth Activating Drop presents the most documented paradox in the Dear, Klairs catalog: algorithmic anti-aging score 76.5 (high) but user rating 3.625/5 (lowest in the catalog) - 4 reviews converge on the lack of visible effect. «No visible results», «not essential». One review qualified with a slight firming effect at 1 month. Texture too liquid reported.»
User feedback
★★★½«I don't know what to think - I've been using these little blue drops for a long time but I've never seen a result, no wow effect or «ah yes anyway», nothing for the skin.»
★★★½«Good product - I like this product, it's good. I keep it in my fridge for a cold effect. But is it essential? I don't think so.»
★★★½«Not convincing - I didn't notice any change or improvement. It's a bit expensive for such a small quantity.»
★★★½«Gentle - soothing and quite moisturizing. My skin is soothed, a little firmer after 1 month of use. Small flaw: it's very liquid.»
Verdict - Paradoxe anti-âge (76.5 algorithm / 3.6/5 rating - 4 reviews). «No visible results». «Not essential». Slight firmness at 1 month (1 review). Too liquid reported.

Visit two paradoxes Dear, Klairs.

A unique structural feature of the catalog: two products with a notable dissonance between high algorithmic score and user rating below 4/5. Documents the limits of pure formulatory evaluation and introduces the notion of «perceived result» vs. «formulatory potential».

Product AA algorithm score Note avis Reason for dissonance
Midnight Blue Youth Activating Drop 76.5 (high) 3.6/5 (4 reviews) «No visible results» - soothing active ingredient with no perceived anti-aging results - texture too liquid
Fundamental Eye Awakening Gel 67.15 (good) 3.3/5 (3 reviews) «Nothing special» - caffeine in pockets: 1 positive review, 2 disappointments
🔍
Why these paradoxes? A well-formulated asset does not necessarily produce a result sufficiently noticeable in a short space of time to generate user satisfaction. Midnight Blue Sérum scores well because guaiazulene and centella are documented - but their action is gradual and subtle, not very visible in the short term. The Midnight Blue cream (same active ingredients, richer format) scores 5/5 out of 9 reviews: the difference is the texture and immediate sensation, not the active ingredients. An invaluable signal to guide your choice in the range.

Dear, Klairs vs alternatives Minimalist K-beauty.

Six marquess with similar positioning. Dear, Klairs stands out for its strong emotional positioning («love letter to a girl with difficult skin») and sensitive skin scores that are systematically higher than the K-beauty average.

Brand Average price Positioning vs Dear, Klairs
Dear, Klairs (Korea) 18-38 € Minimalist - sensitive skin - «Simple but sufficient» - Wishcompany
Skin1004 (Korea) 10-20 € Centella Madagascar - reactive sensitive skin - even more minimalist
ANUA (Korea) 12-22 € Houttuynia cordata - soothing - less structured on ranges

Everything you need really know.

Dear, is Klairs a good brand for sensitive skin?
Yes - Dear, Klairs is one of the best positioned marques K-beauty for sensitive skin in BeautyDecoded. 8 out of 12 products have positive or zero sensitive skin scores. The formulatory charter (no artificial fragrances, no alcohol, no colorants, no parabens) is systematically respected. Visit Supple Preparation Toner Fragrance-free and the Rich Moist Soothing Serum (sensitive skin +1.25) are the two references best suited to hyper-reactive profiles. The only exception is Vitamin C (sensitive skin -7.75) - intermittent use recommended.
What's the difference between Klairs Fragrance Free Toner and Klairs Fragrance Toner?
The difference is clinically significant in BeautyDecoded. The Supple Preparation Toner Fragrance-free (sensitive skin score +1,25) is reformulated without fragrance or essential oils - a superior version for sensitive and hyper-reactive skin. Visit Tonic with original fragrance (sensitive skin score -9,75) is unsuitable for sensitive skin. For all sensitive profiles: the fragrance-free version is formulatively superior and offers the same moisturizing active ingredients. The user rating confirms: 5/5 vs. 3.5/5.
Is Midnight Blue Calming Cream effective on rosacea?
This is the best-documented signal in the catalog. Of the 9 reviews for Midnight Blue Calming Cream, two explicitly document an effect on rosacea: «effective on my rosacea, it calms redness very well» and «suffering from rosacea - this cream is a nugget». The Fundamental Water Gel Cream (redness 76.5) also documents a positive rosacea opinion. The guaiazulen is a documented anti-inflammatory active ingredient. Important: one review notes that for winter, Midnight Blue cream is «not nourishing enough» on dry skin - consider a richer cream on top.
How to use Freshly Juiced Vitamin C to avoid irritation?
The 3 BeautyDecoded reviews converge on the answer: intermittent use optimal, daily use contraindicated. Protocol : 2-3 applications per week in courses of 4-6 weeks. One review documents «an incredible complexion» with this protocol, but skin irritation with prolonged daily use. Ascorbic acid (pure vitamin C) is acidic by nature (pH 2.5-3.5) - a source of irritation with frequent application. Do not combine with exfoliants (AHA/BHA) on the same night. Apply SPF 50+ the next morning.
Is Serum Midnight Blue Youth Activating Drop worth the price?
This is the most talked-about product in the catalog. Anti-aging algorithm score 76.5 (high) but user rating 3.625/5 on 4 reviews - 3 of which document «no visible results» and «not essential». One review qualifies with «slight firmness at 1 month». Guaiazulene and centella are effective soothing active ingredients, but their action is gradual and not very noticeable in the short term. For a visible anti-aging objective: the Vitamin C Freshly Juiced (anti-aging 83.3) or Fundamental Water Gel Cream (anti-aging 79.05). For daily soothing: Midnight Blue cream (5/5, 9 reviews) is better documented.
What is the BeautyDecoded application?
BeautyDecoded is an application that helps you choose cosmetics adapted to your skin type thanks to the’INCI analysis. The application analyzes formulations and generates compatibility scores for 80 skin types. 12 Dear, Klairs products are referenced with 36 reviews. The systematically positive sensitive-skin scores for the Klairs range confirm the consistency of their «fragrance-free / alcohol-free / dye-free» charter. It does not constitute a medical consultation.
