Salicylic acid is one of the primary ingredients in acne medication and other skin-care products. It breaks down sebum and other debris that clogs skin pores and helps to prevent future clogs by slowing down the shedding of skin cells. You can create your own salicylic acid beta hydroxy acid (BHA) serum instead of buying the high-end counterpart from a beauty products retailer.
Place six to nine drops of hazelnut oil in one plastic bottle. Let it rest for a few minutes, and then put six to nine drops of grape-seed oil into the plastic bottle. Shake the bottle to mix the two carrier oils.
Put 3 tbsp. of salicylic acid powder in the plastic bottle with the carrier oils. Shake the bottle to mix the two carrier oils with the powder.
Refrigerate the serum to keep the oils and salicylic acid powder at their most potent strength. Because the product includes no preservative, do not expose it to sunlight or hot temperatures.
