Apply a small amount to target areas or all over skin after cleansing and toning. If needed, follow with a glotherapeutics moisturizer. Use twice daily or as directed. 
Discontinue if no improvement in 3 months. • Lightening effect may not be noticeable on very dark skin. • Limit daily use to 6 months. • After 6 months of daily use, wait 1-2 months before resuming daily regimen. Notes • Sun alert: The AHAs in this product may increase skin’s sensitivity to sunlight. • Wearing a sunscreen daily is highly recommended. • A patch test is highly recommended at least 24-48 hours prior to treatment. • It is particularly important to observe sun protection during a brightening treatment. • Unprotected or excessive sun exposure can delay or inhibit results, or even exacerbate existing pigmentation problems."
