Cleanse and tone your face before use. Place 2 to 3 drops of Advanced Skin Lightening Serum in the palm of your hand and use fingertips to apply a thin layer to face, neck, chest and back of hands as desired once or twice daily. Follow up with your retinol or other target products and moisturizer.
It is important to limit sun exposure and always wear a sunscreen rated SPF 30+ while using hydroquinone.

Hydroquinone is a highly effective ingredient that lightens and corrects moderate to severe dark spots. It is not recommended to exceed 3 consecutive months of use. For best results, use Advanced skin lightening serum for 3 months and then switch to our non-HQ Radiance Serum.
