@jjstiktokreviews: Retinal + Collagen = Retinalogen for Glass Skin! This gentle retinol serum from @P.CALM is suitable for everyday use. You can use this serum in generous amounts because it contains a minimum yet effective amount of retinal, for microdosing your skin. It is scent-free, alcohol-free and the rich texture is great for using as a sleep ampoule mask. I like to massage it in for instant glass skin and smooth and radiant results in the morning. Make sure to use sunscreen during the day, as this could make your skin photosensitive. Available for purchase on Amazon and YesStyle (use my rewards code JJREVIEWS24 for an extra 2-5% off). *Gifted #PCALM #Glassskin #Retinol #Collagen #Retinolagen #Kskincare #Kbeauty #Acneskincare #Amazonfinds #kbeauty #koreanskincare
