Using too many active ingredients in a skincare routine can lead to skin irritation or a compromised skin barrier. Active ingredients, such as acids, retinoids, and potent antioxidants, are effective for various skin concerns; however, overloading the skin with these substances can overwhelm it. This often results in symptoms like redness, peeling, dryness, and sensitivity, signaling irritation.

The skin barrier, which serves as a protective layer, can become damaged when too many actives are applied, leading to increased trans-epidermal water loss and further exacerbating these issues. When the skin barrier is compromised, it becomes less effective at protecting the skin from allergens, irritants, and bacteria, which can contribute to various skin problems.

While increased collagen production, enhanced skin texture, and improved hydration are desirable outcomes of using certain active ingredients, they are often not achievable when the skin is irritated or the barrier is compromised due to the excess of these potent compounds. Therefore, moderation and careful selection of active ingredients are crucial for maintaining skin health.
