Over-Exfoliating Your Skin: How a Dermatologist Says to Help It Heal

Dr. Lauren Penzi says exfoliation is generally best kept to about 1–2 times per week and that over-exfoliation can cause redness, dryness, flaking and increased sensitivity. She notes recovery focuses on gentle cleansing, barrier-repair moisturizers and continued sun protection.

Over-exfoliation has become more common as chemical exfoliants and other active ingredients have grown in popularity. Dr. Lauren Penzi, a board-certified dermatologist at MDCS Dermatology in New York, described how too-frequent or aggressive use of exfoliants and actives can disrupt the skin’s barrier and increase sensitivity. The article reports that this can lead to a range of symptoms from mild irritation to more severe breakdown of the outer skin layer. The piece also summarizes recommended product types and ingredients that clinicians cite for supporting barrier repair. Key details: - Penzi said exfoliation is generally recommended only 1–2 times per week, though this varies by individual skin sensitivity and oil production. - Using powerful actives such as retinol while the skin is dry or barrier-compromised can worsen the problem; Penzi advised pausing exfoliation in those situations. - Common signs reported with over-exfoliation include redness, dryness, flaking, itching, burning or stinging with product application, and sometimes increased acne or areas of eroded skin. - Penzi described a recovery approach centered on a gentle, hydrating cleanser and a thick moisturizer or barrier repair cream, and she emphasized continuing daily sun protection because over-exfoliated skin is more UV-sensitive. - The article highlights barrier-supporting ingredients that can help restore moisture to the outer epidermal layer, including hyaluronic acid, glycerin, ceramides and squalane, and notes a product roundup was provided. Summary: Over-exfoliation can disrupt the skin barrier and increase sensitivity, including to ultraviolet exposure, and the dermatologist described simplifying products and focusing on hydrating and barrier-repair formulations.
