I'm sorry to hear about the persistent black spot on your nose. SkinLite Cream, which contains hydroquinone, mometasone, and tretinoin, is designed to treat melasma and similar pigmentation issues by lightening the skin, reducing inflammation, and promoting skin renewal. It's common for pigmentation to improve while using such creams but return after stopping treatment because the underlying cause may still be present.

Here are some suggestions:

• Continue under medical supervision: Use SkinLite Cream only as prescribed by a dermatologist, who can guide the duration and frequency to minimize side effects.
• Sun protection: Avoid sun exposure and use a broad-spectrum sunscreen daily, as sunlight can worsen pigmentation and reduce treatment effectiveness.
• Avoid abrupt stopping: Sometimes gradual tapering or maintenance therapy is needed to prevent recurrence.
• Consult a dermatologist: If the spot returns after stopping the cream, a dermatologist can evaluate if alternative treatments like chemical peels, laser therapy, or other topical agents are appropriate.
• Monitor for side effects: If you experience irritation, redness, or other skin issues, inform your doctor promptly.

Since pigmentation issues can have various causes, a specialist's assessment is important to tailor treatment safely and effectively.
