Retino-A Micro contains Tretinoin in a microsphere gel formulation, used topically to treat acne and fine wrinkles. The microsphere delivery system allows for slower, controlled release, which helps reduce irritation while maintaining effectiveness.

Mechanism of action:
Tretinoin binds to retinoic acid receptors in the skin, which:

• Increases skin cell turnover, preventing clogged pores and reducing acne

• Stimulates collagen production, improving fine lines and skin texture

• Reduces hyperpigmentation and dark spots over time

Uses:

• Acne vulgaris (whiteheads, blackheads, pimples)

• Fine wrinkles and photoaging

• Hyperpigmentation or dark spots

• Improves skin texture, tone, and overall appearance

Adverse effects:
Common side effects include redness, dryness, peeling, stinging, or mild burning at the application site. Skin may become more sensitive to sunlight, so sun protection is essential. Rarely, severe irritation or allergic reactions may occur.
