คำถาม
Is it possible and safe to achieve instant skin whitening using a wash-off product like a salt scrub? What are the limitations or alternative methods for achieving safe skin brightening?
คำตอบ
Based on the discussion, achieving instant skin whitening with safe and legal cosmetic ingredients in a wash-off product like a salt scrub is not possible. Safe whitening agents require time to show results, typically around 4 weeks. Chemicals that could potentially cause instant lightening are dangerous and not safe for cosmetic use. Safe whitening ingredients are usually formulated in leave-on products for better efficacy.
