Vitamin B12 is a complex, water-soluble molecule, and for this reason, it is generally not effectively absorbed passively through the skin. However, while traditional topical creams offer poor systemic absorption, emerging technologies like microneedle patches are being developed to help answer the question, "Can vitamin B12 be absorbed through the skin?".

While some commercial products claim easy absorption, science shows the skin is an effective barrier, making passive transdermal absorption of vitamin B12 challenging. However, novel technologies are making it possible.
