Potential Ingredients Causing Skin Reactions in Hada Labo vs. Juju Aquamoist
Question
Why does Hada Labo cause small acne or rashes for some users, while Juju Aquamoist does not? Which ingredients in Hada Labo, particularly those added for "skin feel" like Butylene Glycol, are likely responsible, considering the ingredients of a third product (Aqualabel) provided:
Water, Cyclomethicone, Dipropylene Glycol, PEG/PPG-14/7 Dimethyl Ether, Tranexamic Acid, Behenyl Alcohol, Dimethicone, Triethylhexanoin, Phenoxyethanol, Glycerin, Batyl Alcohol, Behenic Acid, PEG-60 Glyceryl Isostearate, PEG-10 Dimethicone, Disodium EDTA, Dipotassium Glycyrrhizate, Polyquaternium-51, Sodium Metabisulfite, Citrus Aurantium Dulcis (Orange) Oil, Lavandula Angustifolla (Lavender) Oil, Potassium Hydroxide, Sodium Hyaluronate, Tocopherol.
Answer
Based on the text you provided, the discussion points to the additional ingredients in Hada Labo compared to the simpler Juju Aquamoist formula as potential causes for skin reactions like small acne or rashes.
The text specifically mentions Butylene Glycol as an ingredient that some research indicates certain individuals may be allergic to. While not explicitly stated to cause acne/rashes, it's highlighted as a potential irritant.
The general principle discussed is that adding more ingredients, especially those primarily for "skin feel" (like Butylene Glycol, Glycerin, PPG-10 Methyl Glucose Ether mentioned for Hada Labo), increases the likelihood of a reaction. The reply from "cosmeceutical7" supports this by suggesting the extra ingredients in Hada Labo (not present in the simpler Juju formula) are the likely culprits if Juju doesn't cause a reaction.
Therefore, based on the information in your text, Butylene Glycol and potentially other added ingredients for skin-feel are the most likely candidates discussed as potential causes for the small acne or rashes experienced by some users of Hada Labo.
