Brilliant Skin Essentials, Hydroquinone Tretinoin Topical Solution Toner 135ml

Volume: 135 ml (Extended size, often purchased separately to replace the smaller bottle found in the standard Rejuvenating Set). Skin Type Suitability: Formulated specifically for oily, blemished, and acne-prone skin types. Not recommended for sensitive or compromised skin barriers. Primary Target Concerns: Moderate to severe cases of acne (pimples, blackheads, whiteheads), dark spots, melasma, post-inflammatory hyperpigmentation, and premature fine lines. Application Frequency: Once daily, strictly at night before bed. Crucial Restraint Period: Continuous use must be capped at a maximum of 2 months to prevent rebound hyperpigmentation (ochronosis).

Hydroquinone (2%): A recognized skin-depigmenting agent. It works at the cellular level by blocking the enzyme tyrosinase, which in turn inhibits melanin production to visibly fade dark spots, age spots, and sun damage. Tretinoin (0.025%): A powerful prescription-strength retinoid (Vitamin A derivative). It forces rapid skin cell renewal, pushes out deep blockages to clear acne, and boosts skin texture.
