What should be avoided in products for oily skin?

Products formulated for oily skin should avoid heavy oil-based ingredients because these can lead to further clogging of pores and exacerbate oiliness. Oily skin is characterized by excess sebum production, and using oil-heavy products can create a greasy appearance and risk of breakouts. Lightweight, water-based formulas are typically more suitable, as they help to hydrate without adding additional oil.

Moisturizing ingredients can still be beneficial for oily skin, as hydration is necessary regardless of skin type. Elements like glycerin or hyaluronic acid provide moisture without the heaviness of oils. Additionally, UV protection is crucial for all skin types, including oily skin, to help prevent damage from sun exposure. Therefore, it's essential for products aimed at those with oily skin to focus on lighter formulations that won’t contribute to the oiliness or clogging of pores.
