They occur mainly on the T-zone (forehead, nose, chin), sometimes on the back or shoulders. They result from excess sebum and dead cells clogging the pores: on contact with air, the blackhead oxidizes and takes on its characteristic black color.<\/p>\n      <p class=\"bd-prose\">Several factors contribute to their appearance: hormonal variations, stress, processed foods, alcohol and tobacco. Oily skin is the most prone to blackheads. In some cases, blackheads can develop into more painful inflammatory pimples, which generally disappear on their own.<\/p>\n\n      <h3>Chemical exfoliation: how it works<\/h3>\n      <p class=\"bd-prose\">Unlike mechanical exfoliation (grains), chemical exfoliation uses exfoliating acids to dissolve the bonds between dead cells and unclog pores gently, without friction.

AHAs (glycolic, lactic) act on the surface, refining skin texture and reviving radiance, in addition to BHA.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>How often should I exfoliate?<\/summary>\n          <div class=\"bd-faq-answer\">Once or twice a week is sufficient in most cases. Exfoliating too frequently weakens the skin barrier and can aggravate imperfections. The frequency should be gradually increased, according to tolerance.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>Do I need sun protection with an exfoliant?<\/summary>\n          <div class=\"bd-faq-answer\">Yes, absolutely. Exfoliating acids, especially AHAs, are photosensitizing: SPF 50+ sun protection in the morning is essential to avoid spots and irritation.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>Can sensitive skin be exfoliated?<\/summary>\n          <div class=\"bd-faq-answer\">Yes, but with caution: low concentrations, reduced frequency, and avoiding strong acids (glycolic 7-8 %) or alcohol-based formulas. A mild BHA at 1 % is often better tolerated.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>What is the BeautyDecoded application?<\/summary>\n          <div class=\"bd-faq-answer\">A mobile application for cosmetic analysis using artificial intelligence. It analyzes INCI lists and generates compatibility scores for 80 skin types. It does not replace a medical consultation, but helps to objectify product selection according to a skin profile.<\/div>\n        <\/details>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ============ DISCLAIMER ============ -->\n  <section class=\"bd-disclaimer\">\n    <p>Information for educational purposes only. It does not replace a medical consultation. Exfoliating acids (AHA, BHA) are photosensitizing and require daily sun protection; they should be introduced gradually, once or twice a week, never in combination with a retinoid on the same evening. BeautyDecoded algorithmic scores do not prejudge individual tolerance: a test on a small area is still recommended, and sensitive or reactive skins will prefer lower concentrations. In case of doubt or inflammatory lesions, seek the advice of a dermatologist. A product on this page has only one review: this feedback is indicative and does not constitute a reliable synthesis.
