Frequently Asked Questions
How often should I use an acne serum?
Start with 2-3 times per week and gradually increase to daily use as your skin adjusts. Overuse can cause irritation or over-drying. Always follow with moisturizer and sunscreen during the day.
Can I use multiple acne-fighting ingredients together?
Be cautious—using too many actives can irritate skin. Start with one serum and add others gradually. Don't combine retinol with AHA/BHA on the same day. Consider alternating nights or using different actives in morning vs. evening.
Will acne serums work for hormonal breakouts?
Topical serums can help reduce inflammation and clear existing breakouts, but hormonal acne often requires internal treatment. Use serums as part of a comprehensive approach that may include dietary changes, stress management, or medical consultation.
