Observe the ingredient list: The ingredient list of cosmetics should list all the ingredients used. If the ingredient list contains hormones such as testosterone (T), estrogen (E), progesterone (P), etc., or contains glucocorticoids such as dexamethasone, prednisone, hydrocortisone, etc., these may contain hormones.
Pay attention to the label: Some brands of cosmetics will indicate "hormone-free" or "hormone-free" on the packaging, but this does not guarantee that they do not contain other ingredients with similar hormonal effects.
Effect of use: If the skin improves significantly in a short period of time after use, but deteriorates rapidly after discontinuation, it may contain hormones.
In addition, symptoms such as thinning of the skin, red blood streaks, excessive hair, and acne after use may also be caused by hormones.
Professional testing: The product can be sent to a professional testing agency to determine whether it contains hormones through chemical analysis.
Skin reaction: Symptoms such as thinning of the skin, red blood streaks, excessive hair, and acne after use may be caused by hormones.
Consult a professional: If you are not sure whether cosmetics contain hormones, you can consult a dermatologist or relevant professional organization to get an accurate judgment.
