Hello: The symptoms you described are known as "post-inflammatory hyperpigmentation." Generally, it tends to fade within a few months.
If treatment is desired, topical whitening agents can be used; however, due to their potential for irritation, the concentration should not be too high! Whitening ingredients include: L-ascorbic acid (Vitamin C), azelaic acid, arbutin, and hydroquinone, among others.

More Info

Black spots on the glans (the head of the penis) can be concerning, especially when they appear suddenly or change in appearance. Based on your description, it sounds like these spots may resemble post-inflammatory hyperpigmentation, which can occur after a skin condition like eczema or dermatitis has resolved. This type of pigmentation is usually harmless and does not indicate a serious underlying condition, especially since you mentioned that the spots are not itchy or painful.

There are several potential causes for black spots on the glans:
1. Post-Inflammatory Hyperpigmentation: As mentioned, this occurs after an inflammatory skin condition heals, leaving behind darker patches. Conditions such as eczema, psoriasis, or even friction can lead to this type of pigmentation.

2. Fungal Infections: Certain fungal infections can cause discoloration of the skin. If there was a history of itching or irritation prior to the appearance of the spots, a fungal infection could be a possibility.

3. Dermatological Conditions: Other skin conditions, such as lichen planus or seborrheic keratosis, can also manifest as dark spots. These conditions may require a dermatologist's evaluation for accurate diagnosis.

4. Melanosis: This is a benign condition characterized by increased melanin production in certain areas of the skin. It can occur in various parts of the body, including the genital area.

5. Moles or Nevi: Sometimes, what appears as a black spot could simply be a mole or a benign nevus. These are usually harmless but should be monitored for any changes in size, shape, or color.

In terms of treatment, if the spots are indeed post-inflammatory hyperpigmentation, they may fade over time without any intervention. However, if you are looking for ways to improve their appearance, consider the following options:
- Topical Treatments: Over-the-counter creams containing ingredients like hydroquinone, kojic acid, or azelaic acid may help lighten hyperpigmented areas. However, it's essential to use these products under the guidance of a healthcare professional, as they can sometimes cause irritation.

- Sun Protection: Protecting the area from sun exposure is crucial, as UV rays can worsen pigmentation. Using a broad-spectrum sunscreen can help prevent further darkening.

- Consult a Dermatologist: If the spots persist, change, or cause concern, it is advisable to consult a dermatologist. They can provide a thorough examination and may recommend treatments such as chemical peels, laser therapy, or prescription-strength topical agents.

- Avoid Irritation: Ensure that the area is kept clean and dry, and avoid any potential irritants, such as harsh soaps or tight clothing, which could exacerbate any underlying conditions.

In conclusion, while black spots on the glans can be alarming, they are often benign and related to previous skin conditions. Monitoring the spots for any changes and consulting a healthcare professional for proper diagnosis and treatment is the best course of action. If you experience any new symptoms, such as pain, itching, or discharge, seek medical attention promptly.
