Skin tone
I have found my face wash i’ve been doing skincare since I was 13. I’m now 25 and I can tell you. I finally found a face that I feel like has made a difference. I don’t have acne prone skin, but my pores and stuff. I’m very insecure about even though I’m probably just nitpicking, but I feel like this face wash has honestly helped so much with matting and making my face look flawless

Best cleanser for oily skin!!!!
I've been using Good Molecules products on my face for the past year and this brand truly does deliver quality for a good price. I purchased this cleanser about a month ago and started using it and fell in love with it. I accidentally left it at a friend's house this past weekend and immediately reordered when I got home. I've always dealt with oily skin issues. I use it in the morning and my face is significantly less oily the entire day. This is now a staple in my skincare routine! 😀

Helped Tighten My Skin & Minimize Pores
Color: Cyano Pink Spicule, Color: Cyano Pink Spicule
I’ve loved the Dr. Melaxin Cyano Pink Spicule Serum! The bottle is small, but it lasted me around 6 months since I only use one pump every other night. When I first started using it, I noticed a tingling sensation, but over time my skin adjusted and I barely notice it now. I’ve definitely seen my pores appear smaller and my skin feels tighter and smoother after using it.

Great for pore reduction
Color: Cyano Pink Spicule
This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.

More than expected
Color: Cyano Pink Spicule
Love, love and recommended to friends. Leaves my skin feeling and looking great. At 69 I don't expect miracles but can definitely see an improvement in texture, glow and line minimizing. I'm hooked and will never be without!
