So I bought a couple of these on a flash sale and my goodness I’m so happy I did I feel like my face needed whatever is in these. I use them nightly with my serums. They never have irritated my face and my skin drinks them. I will definitely continue to buy these for sure. So happy with these

Not only did it take too long to arrive, almost 2 weeks, they then send the wrong product. This is not what I ordered and I have no interest in using it.

I love to use these drops after I do a micro needle they’re not designed for that, but with their design for us to reduce redness and irritation, which happens typically when you do this and these work #tiktokshopcreatorpicks #tiktokshopholidayhaul #sensativeskin #microneedlingtherapy #rednessreliefserum

Hormonal acne around my chin has always been my biggest struggle — especially the post-acne marks that linger. I’ve been trying the renewed Dear Klairs Serum in the new 50ml size, and I love how lightweight and calming it feels in my morning routine. It absorbs quickly, layers easily, and leaves my skin looking smoother and more balanced right away. I’m especially focusing it on my breakout-prone areas and looking forward to seeing what consistent use does over time. @dear, Klairs  #acnetreatment #Kbeauty #Klairs #KlairsEGFserum #koreanskincare

Waking up with smoother skin is my favorite skincare hack. These youth activating peptide drops use EGF, copper peptides, and blueberry extract to help calm skin and improve texture from old acne scars. Night routine must-have.
