Natural astringents tighten the skin and help control surface oil. Lemon juice is commonly used for this purpose in DIY facial preparations because it contains citric acid, which acts as a mild astringent and can help reduce surface oil and tighten pores when diluted properly. It’s often included in masks with honey or yogurt to balance brightness with oil control. But lemon juice can irritate sensitive or dry skin and increases photosensitivity, so it must be diluted with water or another gentle ingredient, used sparingly, and followed by sun protection. Milk, oil, and glycerin don’t provide this tightening action: milk can be soothing with mild exfoliation from lactic acid but isn’t an astringent; oil is nourishing and may clog pores if heavy; glycerin is a humectant that draws moisture, not an astringent.
