1. Tretinoin (0.05% – 0.1%)
Boosts Collagen Production: Reduces fine lines and wrinkles for smoother skin.
Accelerates Cell Turnover: Helps shed dull, damaged skin for a rejuvenated appearance.
2. Hydroquinone (2% – 4%)
Fades Hyperpigmentation: Lightens dark spots, melasma, and age spots by inhibiting melanin production.
3. Niacinamide (Vitamin B3)
Minimizes Pores and Redness: Improves skin texture and tone by reducing inflammation.
Enhances Skin Barrier Function: Retains moisture while calming sensitive skin.
4. Ascorbic Acid (Vitamin C)
Brightens Skin: Reduces dullness and enhances radiance.
Antioxidant Protection: Neutralizes free radicals to prevent premature aging.
Apply a pea-sized amount to the face and neck in the evening after cleansing. Use sunscreen daily, as Tretinoin and Hydroquinone increase sun sensitivity
