Azelaic Acid 12% Serum

Seems to aggrevate my rosacea, may be great for others

As every skincare concern and every person, this is an individual experience and may work perfectly for others. For me personally I seem to wake up with a more red skin than I had the day before. Started using once a week and waited at least 20 mins to apply my moisturiser afterwards all steps hours before bedtime. Hope it works better for others

Love it

Really does what it says and has helps any acne marks I had

Effective
