Cleansing effect refers to the ability of a product to remove impurities from the skin's surface. This includes excess oil (sebum), dirt and pollutants, makeup residues, dead skin cells, and microorganisms (like bacteria). Regular cleansing helps prevent acne and breakouts, blackheads and whiteheads, irritation from leftover makeup or sunscreen, premature aging from pollutant exposure.

A clean skin surface supports a healthy acid mantle — the slightly acidic film that acts as a barrier to bacteria and environmental stressors.

If your skin is dirty or layered with buildup, active ingredients in serums or moisturizers can't penetrate effectively. Cleansing ensures better absorption and maximized benefits from treatments.

Types of Cleansing Effects

Mild Cleansing: Gentle removal of dirt without stripping natural oils - ideal for sensitive or dry skin.
Deep Cleansing: More intense, often targets clogged pores and excess oil - suitable for oily or acne-prone skin.
Exfoliating Cleansing: Includes chemical (like AHAs/BHAs) or physical exfoliants to slough off dead skin cells.

Over-cleansing or using harsh cleansers can disrupt the skin barrier, leading to dryness, irritation, or increased oil production. For sensitive or dry skin, look for non-foaming, low-pH, or oil-based cleansers.
