If your skin became darker after stopping the cream, it is likely because the effect was temporary and not maintained. Follow a consistent skincare routine with a gentle brightening cream containing ingredients like niacinamide or vitamin C, along with a good moisturiser and daily sunscreen, which is essential to prevent darkening from returning. Avoid stopping treatment suddenly and consider consulting a dermatologist for a proper maintenance plan. For a substitute to Acnestar S soap, you can use a mild anti-acne cleanser containing benzoyl peroxide or salicylic acid, which helps control oil and prevent pimples while being gentle on the skin.
