WHO NEEDS THIS?
This serum is best suited to oily skin and acne caused by sebum-overproduction. It's also fungal-acne safe. Just note that it is super strong, so as with any serum with active ingredients, introduce it gradually into your skincare routine to build up your skin's tolerance. Start off with once or twice a week, increasing frequency if your skin permits.While a niacinamide and zinc combo can be super effective at vanquishing acne, it's not for everyone so patch test first!
HOW DO I USE IT?
After opening, replace cap with provided dropper. Apply two to three drops after cleansing and toning, avoiding the eye contour area. You can also just apply the serum on the T-zone or acne-prone areas.
Precautions:
Stop using the product immediately and consult a dermatologist when redness, swelling, or other skin irritations occur, and consult a physician. Avoid applying the product on open wounds or skin inflammation. Keep away from direct sunlight and out of reach of infants and children.
