Its mechanism in this context is not treatment; it is exposure. Small fragrance molecules can trigger irritation or allergic contact dermatitis in susceptible users, especially on already reactive skin.","The mechanism is practical, not magical: vehicle, pH where relevant, dose, frequency, and the rest of the routine decide whether the ingredient feels helpful or irritating. Results should be judged gradually, and sensitive users should introduce it separately from other strong actives."]}],"side_effects":[{"title":"Fragrance Allergic Contact Dermatitis","url":"https://skinknowledgebase.com/side-effects/fragrance-allergic-contact-dermatitis"}]}
