When considering the use of tretinoin 0.025% for oily, acne-prone skin with pigmentation, it's important to understand a few key points:

• Tretinoin is a potent medication that helps with acne and pigmentation by promoting skin cell turnover.

• Using tretinoin without a doctor's guidance can lead to side effects such as irritation, redness, peeling, or worsening of acne if not used properly.

• A healthcare professional can assess your skin condition and recommend the right concentration and usage frequency to minimize side effects and maximize benefits.

• If you have active, pus-filled acne lesions, a doctor might suggest additional treatments or a different approach to avoid irritation.

• It's also important to use sunscreen daily while using tretinoin, as your skin becomes more sensitive to sunlight.

In summary, while tretinoin can be very effective, it's best to consult a dermatologist before starting it to ensure safe and effective treatment tailored to your skin's needs.
