During hot weather, increased oil secretion is common, especially for individuals with oily or combination skin. High environmental temperatures stimulate sebaceous glands, increasing activity. Sweat and accumulated dirt contribute to greasy skin and clogged pores.

However, avoid washing your face more than three times daily. Over-washing can dehydrate the skin and disrupt its protective barrier, hindering effective oil control. A hydrolipid film, composed of water and lipids, covers the skin's surface, maintaining moisture and protecting it from external factors. Frequent washing, especially with strong cleansing products, breaks down this film. This leads to increased transepidermal water loss, making the skin sensitive and prone to irritation.

Skin dehydration triggers a compensatory mechanism, increasing sebum secretion to re-establish the protective film. This results in the "the more you wash, the oilier it gets" phenomenon. Continuous face washing can also disrupt the skin's natural microbiome, fostering bacterial growth. This increases acne risk or worsens existing breakouts. For individuals with dermatitis or sensitive skin, excessive cleansing can cause stinging, redness, burning, or peeling.

You should wash your face about two times a day, in the morning and evening. This effectively cleanses dirt and excess oil while maintaining the skin barrier. If your skin becomes oily during the day, use oil blotting papers to control sebum or rinse with clean water if necessary. Avoid overusing facial cleansers.

Prioritize gentle cleansers with balanced pH, free of alcohol or harsh detergents. Ingredients like niacinamide, zinc, or low-concentration salicylic acid can help control oil and cleanse pores effectively. Use a suitable, lightweight, non-comedogenic moisturizer to rebalance skin moisture.
