This seaweed extract is usually low risk for adults when applied to the skin, but problems mainly come from contamination (like excess iodine or heavy metals) rather than the ingredient itself.
Pick products from brands that say they test for heavy metals and iodine or publish purity testing. Do a small patch test on your inner arm before regular use. Don’t apply to broken, irritated, or infected skin. If you are pregnant, breastfeeding, or have thyroid problems, check with your healthcare provider before using products that list seaweed extracts.
A public ingredient safety database and industry safety reviewers note contamination concerns (iodine and heavy metals such as arsenic, lead, cadmium, mercury, nickel) and recommend limits on impurities. Also one dietary study suggests weak hormone-related effects from eating seaweed; for topical use this is likely low risk but pregnant or breastfeeding people should be cautious. Avoid products that don’t disclose testing or purity information and stop use if you get redness, swelling, or other signs of skin reaction.
