The best form of advertising is through:

• A. Radio
• B. Social media
• C. Satisfied clients
• D. Newspapers

Answer: (C)

Word-of-mouth from satisfied clients is the most effective advertising because it comes from trust and personal experience. In esthetics, people rely on real recommendations from friends, family, or coworkers way more than any paid message. When a client has a great experience, they’re likely to refer others and leave positive reviews, bringing in new clients with a level of credibility paid ads can’t match. Ads on radio, newspapers, or social media can raise awareness, but they don’t carry the same personal trust as a firsthand endorsement. So delivering high-quality service and a positive client experience naturally drives referrals and sustainable growth.
