Works amazingly but the scent is horrible like sweaty self tan
Color: Ultra Dark Bronze
I’m giving this 3 stars due to the scent. It’s horrible. Not so much right away but after about 20 min and even after showering. I’m pretty sure it has self tanner in it. It doesn’t say this! So that’s bad. However, I had no orange on me anywhere or my hands. The good, and if it weren’t for the scent? This stuff works so well! It’s so moisturizing without being too oily. It goes on good and evenly and doesn’t take much at all. My skin feels really good afterwards. It’s advertised as an intensifier and has no sunscreen which is what I wanted. But Omgosh the stink is real! Mixed with sweat it’s even worse.

Another B.tan product I loveeee
Color: Ultra Dark Bronze
Loveeee! I only have experience using in a UV bed but it works wonderfully. Not super oily and gross on the skin, no strong odor but “summer” scent is light and refreshing. I do think it does have instant bronzer in it or potentially gradual tanning affects (like jergens lotion) because I had run a few errands after and my palms had gotten a tad orangey, it was gone after I exfoliated in shower though! Looking forward to using over summer Love all b.tan products. The aerosol self tanner “tanned af” is the best for instant results!

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!
