I had some eyelash extensions removed too soon which was very painful and left my natural lashes very short and sparse. I used dermalmd eyelash growth serum every night and they grew back to normal in 2 weeks, then longer than ever before after another 2 weeks. You do have to keep using it to maintain the really long eyelashes but it is amazing stuff.
Approximately 6 months in the past I commenced having a really tough time with hormonal acne. Some of the shea moisture products helped calm it a bit but it inevitably came back every time. After about weeks of usage of acne serum of dermalmd in the morning and at night my breakouts are gone. Absolutely cleared up. It leaves your face moisturized and glowy while keeping you safe from annoying breakouts.
