What would be the next level of product/solution for blackheads when salicylic acid doesn't work?

If salicylic acid does not effectively treat blackheads, here are some next-level products and solutions you can consider:

Alternatives to Salicylic Acid
Benzoyl Peroxide: Known for its antibacterial properties, it can help treat clogged pores and is especially effective for severe acne. However, it can cause dryness[2][5].
Glycolic Acid: An alpha hydroxy acid (AHA) that dissolves dead skin cells and excess oil, decongesting pores and preventing pimples. It is stronger than lactic acid and suitable for mild to moderate acne[2][5].
Tea Tree Oil: While milder, it has bacteria-repelling properties that can help in reducing acne and blackheads[2].
Sulfur: Can complement salicylic acid and help in unclogging pores[2].
Prescription Treatments
Retinoids: Such as adapalene, which can be prescribed by a dermatologist for more severe cases of blackheads[1][4].
Professional Treatments
Clinical Extraction: Performed by a dermatologist using sterile tools, this can be effective for deeply embedded blackheads. However, DIY extractions are not recommended as they can lead to major breakouts[1][4].
Other Options
Azelaic Acid: Available in various forms, it can help in reducing inflammation and preventing the formation of blackheads[4].
Consulting a dermatologist is highly recommended to determine the best course of treatment tailored to your specific skin condition.
