• Skin irritation: Tretinoin can cause redness, dryness, itching, and peeling of the skin, particularly in the first few weeks of use. This is often referred to as a "retinoid reaction."
• 
  
• Increased sensitivity to sunlight: Tretinoin can make your skin more sensitive to sunlight, increasing the risk of sunburn. It's important to use sunscreen and avoid prolonged sun exposure while using tretinoin.
• 
  
• Stinging or burning sensation: Some people may experience a mild stinging or burning sensation when applying tretinoin.
• 
  
• Temporary worsening of acne: Initially, tretinoin may cause an increase in acne lesions before improvement occurs. This is often referred to as a "purging" period.
• 
  
• Dryness and flakiness: Tretinoin can dry out the skin, leading to flakiness or peeling, especially in areas where it's applied.
• 
  
• Changes in pigmentation: In some cases, tretinoin can cause changes in skin pigmentation, leading to temporary or permanent darkening or lightening of the skin.
