Did You Know?

Did You Know?

Did You Know?
Alpha hydroxy acids (AHAs) are a group of natural acids found in sugar, milk, fruit, and other sources that work by exfoliating dead skin cells on skin’s surface. Within our formula, AHAs can help smooth the look of fine lines and wrinkles and improve the appearance of skin texture and tone over time. Common AHAs found in skincare can include glycolic acid (found in sugar cane), citric acid (found in citrus fruits), lactic acid (found in milk), malic acid (found in apples), tartaric acid (found in grapes), and others.

Lactic Acid is a gentle alpha hydroxy acid (AHA) within our Ferulic Brew Antioxidant Facial Treatment that helps promote the skin’s natural exfoliation process while strengthening, hydrating and balancing skin. Lactic Acid is a unique AHA because of its affinity to skin and its strengthening, hydrating and pH balancing qualities. Within our formulas, Lactic Acid is plant-derived.

Rated 4 out of 5 by from First step after cleansing This Ferulic Brew is the first step after cleansing. It’s supposed to help your serums and moisturizers work better. I like their 5-5-5 directions: Shake the bottle 5 times. Pour 5 drops in your hand. Then press 5 times onto your skin. I’ve used this every night for about 3 weeks now. I found this to be moisturizing and calming on my skin, with no oily residue. It feels cool on my skin too. But, I haven’t seen any long term results yet.

Rated 5 out of 5 by from Awesome essence! I LOVE this essence. It's such a multitasker and so easy to use. I love that it has both lactic acid and squalane because the gentle exfoliation mixed with the hydration made my face feel so healthy and look so glossy. I will definitely be purchasing another bottle when I run out of the bottle graciously provided to me by Kiehl's and BzzAgent!

Rated 4 out of 5 by from Kiehl's Ferulic Brew Antioxidant Facial Treatment I did like Kiehl's Ferulic Brew Antioxidant Facial Treatment more than any serum I've tried before. I liked the herbal scent. I used this after washing my face every night. I didn't like the film it left on my skin. I used 5 drops and pressed it into my skin like the directions specified. I did notice an improvement in my skin. I received this product complimentary but all views are my own.

Rated 5 out of 5 by from Youthful skin without complication Kiehl's Ferulic Brew formula is brewed for over 120 hours, so you know it is the best quality! This potent product works to reduce fine lines, rejuvenate the skin's texture, and boost a healthy radiance. Even better is that it is fast acting and absorbs quickly. To use, I lightly saturate a makeup swab and apply evenly to my face and neck. They have a 5-5-5 method: Shake the bottle 5 times to properly mix, pour 5 generous drops into the palms of your hand or cotton ball, gently press 5 times onto your face and neck. Follow with moisturizer. You will notice more youthful looking skin after one use! This product can be used morning and night.

Rated 4 out of 5 by from Its ok I am not crazy about the smell but I do like that is a light weight feeling oil. I work around a ton of chemicals that dry out my skin and using this really help replenish the moisture of my skin.

Rated 4 out of 5 by from healthy looking skin To start with the bottle for this face treatment looks very nice and sleek. I always enjoy when my products come with great packaging . This product has a simple easy to use system of 5,5,5; with 5 shakes, 5 drops, and 5 presses into your skin. I love a routine like this and it is relaxing to follow. I do think 5 drops is almost to much for my skin but I like that the oil can go a long ways. They packed so many good ingredients in this bottle and my normal skin has really been soaking up and enjoying it. I feel after two weeks my skin looks more radiant, smoother, and overall healthy. The product itself does have a light scent but I do not feel that it is overpowering or awful. I overall have enjoyed including this product into my daily skincare routine.

Rated 5 out of 5 by from Great Gentle Exfoliant I've been using this product for a couple weeks now. I really like how light the product is on my face. It doesn't make me feel oily. I've been putting it on my face and neck, and my skin has been feeling more fresh. It also works great as an exfoliating mask. I tried mixing this essence with a cream and left it on my face for 10 minutes. When I scrubbed my face afterwards, I could see the dead skin wash away! I love this product!
