Based on limited meta-analysis data showing cosmetic benefits. Conservative effectiveness estimate due to cosmetic nature of outcomes and limited study population. Higher doses may cause orange skin tint.
Based on limited meta-analysis (n=12) showing improved skin hydration. Oral bioavailability is questionable and most dermatological studies used topical/injectable forms. Low molecular weight forms may have better absorption.
