It sounds frustrating to have pimples, blackheads, and dark spots on your face for several years. Using a topical treatment like Tretinoin 0.025% cream can help by unclogging pores, reducing pimples and blackheads, and improving skin texture over time.

• Tretinoin cream works by promoting skin cell turnover, which can gradually fade dark spots and prevent new acne.
• Apply it as directed by a dermatologist, usually once daily at night, avoiding sensitive areas like eyes and mouth.
• Protect your skin from sun exposure by using sunscreen daily, as tretinoin can increase sun sensitivity.
• Some mild side effects like redness, peeling, or dryness may occur initially but often improve with continued use.
• Since your spots have persisted for years, it’s important to consult a dermatologist to confirm the diagnosis and tailor treatment, possibly combining other therapies if needed.
