@newworld_reviewer: ⭐️⭐️⭐️⭐️⭐️ @Klairs Global Official @dear, Klairs Dear Klairs EGF Serum: Blue Youth Activating Drop Look at the rating on Olive Young. DearKlairs EGF Serum: Blue Youth Activating Drop is actually what Koreans use. It is Korean and Olive Young No. 1 EGF Serum. One bottle sold every 4 seconds. This serum is solution for acne prone skin. It is cooling and soothing and reduces redness. It is not moisturizing and gets absorbed quickly. I am on my second bottle. #acnetreatment #Kbeauty #Klairs #KlairsEGFserum #koreanskincare
