It\u2019s actually somewhat of a hero.

This chemical exfoliator is often found in toners, serums, exfoliators and creams for improved skin texture.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766158827516\">\n<h3 class=\"schema-faq-question\">How does salicylic acid help with acne?<\/h3>\n<p class=\"schema-faq-answer\">Salicylic acid, a beta hydroxy acid (BHA), is highly effective at fighting acne by penetrating deep into your pores. It removes dead skin cells, impurities and excess sebum, but overuse can leave your skin feeling dry, so spot-treat blemishes or use a salicylic acid cleanser if you have acne.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766158827517\">\n<h3 class=\"schema-faq-question\">Why is hyaluronic acid popular in skincare?<\/h3>\n<p class=\"schema-faq-answer\">Hyaluronic acid is valued for its water-binding ability, as just one gram can hold up to six litres of water. It naturally occurs in your skin and stimulates your body\u2019s own production, penetrating deeply to boost hydration and support connective tissue.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766158827518\">\n<h3 class=\"schema-faq-question\">When should you apply Vitamin C to your skin?<\/h3>\n<p class=\"schema-faq-answer\">You should apply Vitamin C (ascorbic acid) at night, when most skin healing happens. Vitamin C is a powerful antioxidant that helps shield you from environmental stressors like pollution and blue light, while also evening out your skin tone and brightening your complexion.<\/div>\n<div class=\"schema-faq-section\" id=\"faq-question-1766158827519\">\n<h3 class=\"schema-faq-question\">How should you start using azelaic acid in your routine?<\/h3>\n<p class=\"schema-faq-answer\">Begin by using azelaic acid every other evening to help your skin adjust, as it is milder than AHAs but still effective at treating conditions like acne and rosacea. Azelaic acid helps reduce inflammation, redness and the build-up of free fatty acids in your skin.<\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>We have to admit, the word \u2018acid\u2019 doesn\u2019t exactly sound inviting when we\u2019re talking about things to put on our skin but we swear it is.
