Deep blackheads can be challenging to remove, but there are several methods you can try:

1. Lemon Juice and Baking Soda: Make a paste using lemon juice and baking soda, apply it to the affected areas, and gently scrub to help remove blackheads. Lemon juice acts as an astringent and baking soda helps to exfoliate the skin.

2. Steam: Steam your face before applying any treatment. This helps to open up the pores and makes blackhead removal easier.

3. Salicylic Acid: Use products containing salicylic acid, which can help to unclog pores and prevent the formation of new blackheads.

4. Clay Masks: Clay masks can help to draw out impurities, including blackheads, from the skin.

5. Professional Extraction: Consider seeing a dermatologist or an esthetician for professional extraction of deep blackheads.

Remember to cleanse your skin regularly and avoid using harsh products that can irritate the skin and worsen the problem. Additionally, it’s important to note that picking or squeezing blackheads can lead to scarring, so it’s best to use gentle methods for removal.
