Review: high quality serum - Wonderful serum for moisture and glow . Very high quality product, odorless, adds a lot of moisture, suitable for winter and summer, not heavy. Absorbs quickly and does not remain oily. I have dry and sensitive skin. I incorporate the product as part of a skincare routine, after using the same company's toner and as a final step before using a moisturizer. Highly recommend.
Review: Klairs is the best skincare! - It is super comfortable and moisturizing. I have only started using Klairs for just the past week and already my skin is looking so much younger and I feel so refreshed. I have really bad rosacea but since I started using Klairs the redness is fading fast and my skin is feeling really soft and comfortable, not irritated anymore. Also fixing a lot of my visible sun damage.

### ⭐⭐⭐⭐⭐ high quality serum
*by A***R on May 7, 2025*

Wonderful serum for moisture and glow . Very high quality product, odorless, adds a lot of moisture, suitable for winter and summer, not heavy. Absorbs quickly and does not remain oily. I have dry and sensitive skin. I incorporate the product as part of a skincare routine, after using the same company's toner and as a final step before using a moisturizer. Highly recommend.

### ⭐⭐⭐⭐⭐ Klairs is the best skincare!
*by A***R on August 17, 2020*

It is super comfortable and moisturizing. I have only started using Klairs for just the past week and already my skin is looking so much younger and I feel so refreshed. I have really bad rosacea but since I started using Klairs the redness is fading fast and my skin is feeling really soft and comfortable, not irritated anymore. Also fixing a lot of my visible sun damage.

### ⭐⭐⭐⭐⭐ Allergy-prone & combination-skin holy grail!
*by D***. on August 3, 2021*

Very lightweight, no fragrance & gives a glass-skin look (without being overly greasy)! I have acne-prone, combination skin that is often dehydrated, in addition to numerous allergies. I mostly layer this product over moisturizer (applied over my serums/wet skin) as my last step prior to sunscreen. It gives a beautiful, dewy look while preventing transepidermal water loss, and has not caused any breakouts or irritation for me. :)
