Melalite XL Cream contains hydroquinone, mometasone, and tretinoin, a strong combination usually prescribed for certain skin conditions under medical supervision. It is not recommended to use it on your own, especially in sensitive areas like the bikini region, as it can cause irritation, skin thinning, or other side effects. Even in thicker areas such as elbows and knees, it should only be used if a doctor advises it after examining your skin. The safest approach is to consult a dermatologist, who can assess your condition and guide you to appropriate, safer treatment options.

The light brown spots on your nose and cheeks are likely melasma, which can return after stopping treatment. You should consult a doctor or dermatologist for safe long-term management, continue strict sun protection, and avoid unsupervised use of steroid-based creams like Melalite XL to prevent skin thinning and recurrence.
