Detailed answer

If you have dull skin, it is best to avoid skincare ingredients that can further strip away moisture and irritate your skin. Alcohol, commonly found in toners and astringents, can be drying and cause further dullness. Fragrances, whether synthetic or natural, can also be irritating to the skin and lead to inflammation, making your skin look more dull. Additionally, harsh exfoliants like physical scrubs or chemical peels can cause micro-tears in the skin, exacerbating dullness. Instead, opt for gentle and hydrating ingredients like hyaluronic acid, vitamin C, and alpha hydroxy acids (AHAs) to brighten and improve the overall appearance of your skin.
