Yes, oily skin can change with seasons and weather. In summer or humid conditions, gel or lotion based moisturizers usually feel lighter and more comfortable. During cooler months or at night, the skin may feel tighter after cleansing, so some people switch to slightly richer textures. Many adjust textures rather than completely changing their routine.

A moisturizer for oily skin is best used twice daily, in the morning and at night. Morning use helps the skin feel comfortable under sunscreen and makeup during the day. Night application supports the skin after cleansing and daily exposure to pollution, sweat, and indoor air conditioning. Using a small amount consistently often works better than using a larger quantity occasionally.

Serums are applied before moisturizer because they have a lighter texture and are designed to absorb quickly into the skin. Moisturiser is applied after to seal in hydration and help the skin feel comfortable for longer. This order allows each product to work as intended without making the skin feel heavy or over layered.
