What to do against blackheads?
There are remedies of yesteryear to fight blackheads and get rid of excess oil from the skin.

Potato
Cut an untreated potato into slices. Apply the pucks directly to your blackheads while massaging. Renew the operation once a day. This trick eliminates excess oil from the skin and prevents the appearance of blackheads.
The lemon
Cut 1 lemon in half. Take a Cotton Swab that you soak with lemon juice. Dab the black-dot areas of the face. You have to do it twice a day for a full week.. Attention, the lemon is photosensitizing, be careful not to expose you to the sun after its application on the skin!
