COSRX Aha 7 Whitehead Power Liquid
The COSRX Aha 7 Whitehead Power Liquid is a cult-favorite chemical exfoliant designed to target stubborn whiteheads and uneven skin texture. Formulated by the renowned K-beauty brand COSRX, this liquid treatment utilizes 7% Glycolic Acid (AHA) and Pyrus Malus (Apple) Fruit Water to gently melt away dead skin cells and clear trapped debris from within the pores. Unlike harsh physical scrubs, this power liquid provides a chemical approach to resurfacing the skin, making it highly effective for those dealing with congestion and dullness. In addition to its exfoliating properties, the inclusion of Niacinamide helps to brighten the complexion and refine the appearance of pores, while Sodium Hyaluronate ensures the skin remains hydrated during the process. The texture is a lightweight, watery liquid that absorbs quickly without leaving a greasy residue, making it an easy addition to any evening routine. For users with acne-prone skin, this product offers a dual benefit: it prevents new clogs from forming while improving the overall clarity and radiance of the skin.
Our Analysis
Our analysis of the COSRX Aha 7 Whitehead Power Liquid confirms a low comedogenic risk, making it an excellent choice for those prone to breakouts. The formulation is notably free of common pore-clogging oils, waxes, and heavy esters that often trigger acne. Instead, it relies on a clean base of Apple Fruit Water and Glycolic Acid to promote cellular turnover. Because there are no flagged ingredients, this product is unlikely to cause 'cosmetic acne' or exacerbate existing congestion. It focuses on chemical exfoliation to keep pores clear rather than introducing potential irritants or occlusives.
Skin Type Recommendations
This product is ideal for oily, combination, and acne-prone skin types struggling with whiteheads and texture. Its lightweight formula won't weigh down oily skin. While effective for most, those with very sensitive or dry skin should patch test first due to the 7% Glycolic Acid concentration, which can be potent.
Flagged Ingredients
