Newer studies show that the intake of aluminium through your skin is very low and that there is no increased risk to your health. The risk from aluminium in food is higher.

Conclusion: “… The SCCS considers that the systemic exposure to aluminium via daily applications of cosmetic products does not add significantly to the systemic body burden of aluminium from other sources. Exposure to aluminium may also occur from sources other than cosmetic products, and a major source of aluminium in the population is the diet. This assessment has not taken into account the daily dietary intake of aluminium.”
