When it comes to treating dark skin discoloration, particularly on the buttocks, there are several effective options available, especially considering the history of acne and skin irritation you've described. The discoloration you're experiencing is likely due to post-inflammatory hyperpigmentation (PIH), which is common after skin injuries such as those caused by acne, scratching, or friction.
First, it's important to understand that while some treatments can help lighten these dark spots, they often require time and consistency. The use of products containing ingredients like azelaic acid, glycolic acid, and kojic acid can be beneficial. These ingredients work by promoting cell turnover and inhibiting melanin production, which can help in reducing the appearance of dark spots over time.

You mentioned using salicylic acid and glycolic acid lotions, which are excellent choices for smoothing the skin texture and preventing further breakouts. However, for the specific issue of hyperpigmentation, you might want to consider incorporating additional active ingredients into your routine.
1. Azelaic Acid: This is a multi-functional ingredient that not only helps with acne but also has skin-lightening properties. It can reduce the appearance of dark spots and improve overall skin tone.

2. Kojic Acid: This is another effective ingredient for treating hyperpigmentation. It works by inhibiting the enzyme responsible for melanin production.

3. Hydroquinone: This is a potent skin-lightening agent that can be effective for treating dark spots. However, it should be used with caution and typically under the guidance of a dermatologist, as prolonged use can lead to side effects.

4. Niacinamide: This is a form of vitamin B3 that can help improve skin tone and texture. It has anti-inflammatory properties and can also help with hyperpigmentation.

5. Retinoids: Topical retinoids (like tretinoin) can promote cell turnover and help fade dark spots over time. They can also improve the overall texture of the skin.

6. Chemical Peels: If over-the-counter products are not yielding the desired results, you might consider professional treatments such as chemical peels. These can help exfoliate the skin more deeply and promote the growth of new, evenly pigmented skin.

7. Laser Treatments: For more severe cases of hyperpigmentation that do not respond to topical treatments, laser therapies can be effective. These treatments target the melanin in the skin and can significantly reduce dark spots.

In terms of your question about using azelaic acid or other brightening creams, they can indeed be effective, especially when combined with other treatments. However, it’s crucial to be patient, as significant changes can take time—often several weeks to months—to become noticeable.

Lastly, it's essential to protect your skin from further sun exposure, as UV rays can exacerbate hyperpigmentation. Using a broad-spectrum sunscreen with an SPF of at least 30 daily is crucial, even on cloudy days or when indoors, as UV rays can penetrate windows.

In conclusion, while topical treatments can be effective for treating dark skin discoloration, combining them with professional treatments and consistent sun protection will yield the best results. Consulting with a dermatologist can provide you with a tailored treatment plan that addresses your specific skin concerns and helps you achieve the desired outcome.
