In pH-stabilized cosmetic formulations, this interaction is not clinically significant.<\/p>\n\n\n\n<p><strong>Is niacinamide suitable during pregnancy?<\/strong><\/p>\n\n\n\n<p>Yes - it's one of the few cosmetically active ingredients considered compatible with pregnancy and breastfeeding. It represents a relevant alternative to retinol (contraindicated) for pregnant women. Consult your doctor, however.<\/p>\n\n\n\n<p><strong>How long will it take to see the results?<\/strong><\/p>\n\n\n\n<p>Improved radiance and reduced redness: 2-4 weeks. Reduction of pigmentation spots and action on pores: 8-12 weeks. Action on fine lines and firmness: 12-16 weeks.<\/p>\n\n\n\n<p><strong>Niacinamide or retinol: which to choose?<\/strong><\/p>\n\n\n\n<p>They are complementary rather than substitutes. If you can use both: retinol in the evening + niacinamide as support. If you cannot tolerate retinol or are contraindicated (pregnancy): niacinamide alone can provide anti-aging and anti-dark spot prevention, but with a longer duration of action.<\/p>\n\n\n\n<p><em>BeautyDecoded - Independent medical information.<\/em><\/p>\n\n\n\n<blockquote class=\"instagram-media\" data-instgrm-captioned data-instgrm-permalink=\"https:\/\/www.instagram.com\/reel\/Cn9AaFSI2oX\/?utm_source=ig_embed&amp;utm_campaign=loading\" data-instgrm-version=\"14\" style=\" background:#FFF;
