Detailed answer

To properly use retinol for acne, start with a low concentration (0.025% or 0.05%) to avoid irritation. Apply a pea-sized amount to clean, dry skin once a week before bedtime. Gradually increase usage to 2-3 times a week, then eventually every night, depending on your skin's tolerance. Allow retinol to absorb completely before applying any other skincare products or moisturizer. Avoid using retinol if you have eczema, psoriasis, or are pregnant. Always follow the instructions provided by the retinol product and consult with a dermatologist if you have any concerns or questions.
