Comedones form when our skin cells lining the sebaceous ducts proliferate abnormally. Combined with the increased sebum production that is common in acne-prone skin and some skin debris such as cosmetic residue, these debris can block the sebaceous duct and result in a comedo.
Certain topical medications that are “comedolytic” can help. Suitable agents include benzoyl peroxide and topical retinoids such as adapalene and treitinoin. Topical chemical peels containing glycolic and salicylic are frequently useful too. In severe cases oral medications such as isotreitinoin may be used.
You may also want to choose oil-free and non-comedogenic cosmetics and facial products. With regard to the products you are currently using, Hyaluronic acid is a very good component to improve skin hydration but does not have any exfoliating or comedolytic properties.
Do seek a consult with a trusted doctor for a more in-depth solution to your concerns. Hope this helps!
