Several factors can contribute to skin issues like acne, blemishes, and uneven texture, which can result in not clear skin. Some common causes include:

1. Hormonal Imbalance: Changes in hormonal levels can lead to increased sebum production, which can clog pores and cause breakouts.
2. Poor Skincare Routine: Using harsh products, not cleansing properly, or skipping skincare steps can lead to skin issues.
3. Diet: Consuming a high-sugar or high-dairy diet, which can exacerbate acne.
4. Stress: High levels of stress can trigger hormonal imbalances and inflammation, affecting the skin.
5. Genetics: Some people are genetically predisposed to certain skin issues like acne or eczema.
6. Environmental Factors: Exposure to pollutants, UV radiation, and harsh weather conditions can also impact skin health.
7. Not Drinking Enough Water: Dehydration can lead to dull and dry skin, making it more prone to issues.

Improving skincare habits, managing stress, staying hydrated, eating a balanced diet, and protecting skin from environmental factors can help achieve clearer skin. If the issue persists, it’s advisable to consult a dermatologist for personalized advice and treatment options.
