Klairs

Klairs was founded in Seoul in 2010 with a principle that seems almost counter-intuitive in the world of K-Beauty: less is more. "Simple but Enough / Basic but Ultimate / Mild but Powerful" is the brand's mantra, making simplicity its strength.

Founded as part of Wishcompany, Klairs is now present in over 80 countries and has built one of the most loyal communities in the global K-Beauty scene. The reason? Formulas that truly work even on sensitive skin, without potentially irritating ingredients such as artificial fragrances, denatured alcohol, parabens, and colorants.

Every product undergoes Primary Skin Irritation Testing on sensitive skin. This is not a minor detail: it is proof that Klairs formulates its products with those who have easily reactive skin in mind first and foremost.

Klairs starts with a belief: a skincare routine should soothe the skin, not stress it. That's why every formula is stripped down to the essentials, with ingredients that play a precise role and no decorative or trendy elements added for marketing.

The Primary Skin Irritation Testing is conducted before the launch of each product: it is applied to sensitive skin to verify that it does not cause reactions. It is an additional safety filter compared to standard tests, and it is why Klairs is often recommended by dermatologists to those with reactive skin.

  • 5% Pure Vitamin C (Freshly Juiced Vitamin C Serum): Pure L-Ascorbic Acid, naturally unstable but effective in small percentages. Water-based formula, designed for those who want to approach vitamin C without the typical irritation of high concentrations
  • Guaiazulene (Midnight Blue Calming Cream): derived from blue chamomile, with one of the most powerful soothing actions in cosmetic formulation. The intense blue color is natural, not a dye
  • Beta-Glucan: skin immunomodulator, strengthens the barrier and calms inflammatory reactions. Present in formulas for sensitive and reactive skin
  • Ceramides and Jojoba (Rich Moist Soothing Cream): to restore compromised skin barrier and deeply nourish dry skin
  • Phyto-Oligo Complex (patented): blend of Althaea Rosea extract and Aloe Vera for long-term hydration and soothing
  • Sensitive and reactive skin: Klairs is built around this need. Primary Skin Irritation Testing and the absence of common irritants make it ideal.
  • Dry and dehydrated skin: ceramides, beta-glucan and Phyto-Oligo for barrier and deep hydration.
  • Dull and uneven skin: 5% vitamin C for those who want a gradual and gentle approach.
  • Mild acne tendency: guaiazulene and light formulas to soothe without clogging.
  • Normal skin looking for a minimalist and reliable routine.

Klairs is the brand we recommend to those approaching K-Beauty for the first time with difficult skin, and to those who, after years of attempts, are finally looking for something that won't cause reactions.

Klairs' simplicity is not a lack of formulation; it is a choice. And this choice, supported by real tests on sensitive skin and double ethical certifications, is exactly the kind of rigor we look for in our selection.

  • Is Klairs Vitamin C Serum suitable for sensitive skin? The 5% L-Ascorbic Acid concentration is specifically designed for those who want the benefits of Vitamin C (radiance, even tone, antioxidant) without the typical irritation risks of high-concentration formulas. It is still a pure acid, so introduce it gradually, starting with every-other-day applications.
  • What does KARA cruelty-free mean? KARA (Korea Animal Rights Advocates) is the Korean cruelty-free certification body. It means that no product or ingredient is tested on animals, either by the brand or by its suppliers. It complements vegan certification, which guarantees the absence of animal-derived ingredients.
  • Does Klairs use perfumes? No. The entire Klairs line is formulated without added artificial perfumes. Some products may have a slight natural scent from botanical ingredients, but they do not contain synthetic fragrances or irritating essential oils.
  • What is Primary Skin Irritation Testing? It is a safety test conducted on volunteers with sensitive skin before the launch of each product. It verifies that the formula does not cause redness, itching, or skin reactions in the most reactive subjects. It is an additional safety filter beyond standard legal tests.
