Both IV drips and intramuscular injections deliver glutathione effectively, but they have different advantages: IV Drips (Recommended by Most Dermatologists) Advantages: 100% bioavailability entire dose enters bloodstream Can deliver higher doses safely (1200mg+) Allows combination with vitamin C, collagen, other nutrients More comfortable no muscle pain after treatment Faster visible results due to higher doses Disadvantages: Takes 30-45 minutes per session (vs 5 minutes for injection) Costs 30-50% more than injections Requires IV insertion (some people dislike needles in veins) Intramuscular Injections Advantages: Quick administration (5-10 minutes) Lower cost per session Can be done at home by trained nurses (in some countries) No IV equipment needed Disadvantages: Lower doses (typically 600mg max) Painful injection site for 1-2 days Slower absorption compared to IV Cannot combine with multiple nutrients as easily Our Recommendation: IV drips are superior for skin brightening due to higher doses and better combination possibilities
