Azelaic acid is an excellent alternative, even during pregnancy. Introduce one active ingredient at a time, gradually.<\/div>\n<\/details>\n<details class=\"bd-faq-item\">\n<summary>Is it necessary to moisturize acne-prone skin?<\/summary>\n<div class=\"bd-faq-answer\">Yes, oily acne-prone skin needs moisturizing, with a light, non-comedogenic texture. Not moisturizing weakens the skin barrier and can increase sebum production, which worsens acne.<\/div>\n<\/details>\n<details class=\"bd-faq-item\">\n<summary>Is it possible to combine several anti-acne active ingredients?<\/summary>\n<div class=\"bd-faq-answer\">Yes, but gradually and cautiously. Niacinamide combines well with most active ingredients. On the other hand, avoid using too many exfoliating or irritating active ingredients on the same evening, and stop using retinol a few days before and after a peel.<\/div>\n<\/details>\n<details class=\"bd-faq-item\">\n<summary>Does sun exposure improve acne?<\/summary>\n<div class=\"bd-faq-answer\">Sunlight gives a deceptive short-term improvement, but then causes a rebound effect (hyperkeratinization, squalene oxidation) and a risk of post-inflammatory hyperpigmentation. It's best to avoid exposure and use appropriate sun protection.<\/div>\n<\/details>\n<details class=\"bd-faq-item\">\n<summary>Does diet affect acne?<\/summary>\n<div class=\"bd-faq-answer\">The scientific consensus is that foods with a high glycemic index should be limited. Dairy products can aggravate acne in some people: stopping them for a month, then gradually reintroducing them, is a good way to test your case.<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/section>\n<section class=\"bd-section\">\n<div class=\"bd-wrap\"><span class=\"bd-section-label\">Further information<\/span><\/p>\n<h2>Our guides <em>anti-acne<\/em> detailed<\/h2>\n<div class=\"bd-hub-grid\"><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-acne-care\/anti-acne-cream\/\"><span class=\"bd-hub-card-tag\">Comparison<\/span><\/p>\n<h3>Best anti-acne creams<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-acne-care\/anti-acne-serum\/\"><span class=\"bd-hub-card-tag\">Comparison<\/span><\/p>\n<h3>Best anti-acne serums<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-acne-care\/acne-oily-skin\/\"><span class=\"bd-hub-card-tag\">By skin<\/span><\/p>\n<h3>Acne &amp; oily skin<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-acne-care\/acne-dry-skin\/\"><span class=\"bd-hub-card-tag\">By skin<\/span><\/p>\n<h3>Acne &amp; dry skin<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-acne-care\/anti-acne-diet\/\"><span class=\"bd-hub-card-tag\">Decoding<\/span><\/p>\n<h3>Anti-acne diet<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-blemish-care\/\"><span class=\"bd-hub-card-tag\">Guide<\/span><\/p>\n<h3>Anti-imperfection care<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><a class=\"bd-hub-card\" href=\"https:\/\/www.beautydecoded.com\/en\/facial-care\/anti-blackhead-care\/\"><span class=\"bd-hub-card-tag\">Guide<\/span><\/p>\n<h3>Anti-blackhead care<\/h3>\n<p><span class=\"bd-hub-card-arrow\">Read the guide \u2192<\/span><\/a><\/div>\n<\/div>\n<\/section>\n<div class=\"bd-sig\"><strong>Dr Sylvain David<\/strong><span>Plastic and aesthetic surgeon - Founder of BeautyDecoded<\/span><\/div>\n<div class=\"bd-disclaimer\">\n<p>Information for educational purposes only.
