The use of oil-based products is particularly beneficial for individuals with dry skin. This is because dry skin lacks adequate moisture and can appear flaky, rough, or tight. Oil-based products contain emollients that help to seal in moisture, providing a barrier that prevents water loss from the skin. They also add hydration and nourishment, which is crucial for maintaining the skin’s suppleness. As a result, these products can significantly improve the texture and overall appearance of dry skin.

Oily skin tends to overproduce sebum, and while it may benefit from lightweight moisturizers, oil-based products can exacerbate shine and breakouts. Combination skin, which exhibits both oily and dry areas, may require specific formulations that balance the needs of different zones, making oil-based products less ideal for some areas. Normal skin, being generally balanced, does not require the extra hydration that oil-based products provide, although it can benefit from them depending on individual preferences and environmental factors.
