Kiehl’s Ultra Pure High-Potency Serums
American apothecary brand Kiehl’s has just launched one of the most exciting skincare collections of 2023 – a trio of ultra pure high-potency serums that are each formulated with 10 or less ingredients. I can’t tell you how difficult this is to achieve in chemistry. Active ingredients often don’t blend well with other actives in a formulation. The fewer the ingredients, the more difficult it is to blend. The fact that Kiehl’s scientists were able to achieve this feat in three different products is incredible.
Why is this important? The fewer the ingredients, the less chance there is for those with sensitive skin to react to a formula. In fact, the Canadian Dermatologist Association has recognized these serums for ‘low potential for irritation’. Each is fragrance free, colorant free, clean, vegan-friendly, hypoallergenic and tested on sensitive skin. Even more impressive is they are guaranteed potent and stable for two years or more.
Kiehl’s Ultra Pure High-Potency Serum 5% Niacinamide
The first serum, a 5% Niacinamide formula is ideal for anyone with oily skin. It addresses imperfections, redness, shine reductions and oil control.
Kiehl’s Ultra Pure High-Potency Serum 1.5% Hyaluronic Acid
If dry sky is your main concern, this hyaluronic acid serum is for you. It’s helps boost plumpness, bounce, suppleness and deep hydration. Gently massage into your skin after cleansing and allow to absorb for a minute or two before applying your moisturizer.
Kiehl’s Ultra Pure High-Potency Serum 9.8% Glycolic Acid
For those concerned with skin texture and radiance, the glycolic acid targets texture, pores, glow and exfoliation. This particular serum contains only seven ingredients.
With any serum, be sure to give it a full eight weeks to show optimum results.

April 19, 2023 at 12:06 amI love the fact that these Kiehl’s serums are fragrance and colorant free, made with very few ingredients yet guaranteed to be potent and stable for at least 2 years. I look forward to trying the glycolic acid serum.

April 6, 2023 at 8:10 pmI’ve been using Kiehl’s products for years now, and am loving them! I’m sensitive to fragrances, and happy to say that majority of the products I tried are fragrance-free. I Love their creams for sensitive skin, face masks and serums, and hand cream. Very excited to try new serums and to add them to my routine.

April 6, 2023 at 4:59 pmIt is nice to see the progress the beauty industry is making towards using fewer ingredients and more natural combinations. 2 out of 4 of us in my household have issues with scents (even light scents -alas no perfume for me) so having items that are scent free is a big plus. I do not have particularly sensitive skin but many people do so something which should work for those with sensitive skin is very very good. I don’t have oily or dry skin so perhaps the third serum: Kiehl’s Ultra Pure High-Potency Serum 9.8% Glycolic Acid would be the best choice for me.

March 2, 2023 at 10:38 amSerums are so important in my beauty care, not only for facial skincare but, neckline and décolletage. Haven’t used Niacinamide though, definitely looking it up now. Thanks!

June 2, 2023 at 8:31 amKiehl’s scientist and their research team are great. The serums seems really promising and gentle for skin. I’m happy that they make the active serums with no added color, fragrance or other unnecessary ingredients. In this way the skin will get the maximum benefit of that active.

February 24, 2023 at 6:47 pmWow! This is incredible news! I saw you showcase these on Cityline, and I was just so impressed! You’re so right about how hard that is to achieve in chemistry. This is just another reason I love Kiehl’s so much! They focus on the science, and that’s so important! It’s obviously paying off very well for them, too! Thanks so much for sharing these with us, Dave! Hope you have a wonderful weekend!! xoxoJJ
