Cotton-tipped applicators are generally used to apply creams and balms to small areas. They are particularly useful for coloring eyebrows, removing excess product during facials, or touching up makeup and nail polish. They can also be used for applying glycolic acid treatments, as well as other esthetic procedures that require precision and easy application. Glycolic applicators are usually lint-free, non-absorbent, and double-ended. They also have extra-large heads compared to other cotton-tipped applicators.
