Onlymyhealth.com claims to have a home remedy treatment to reduce blackheads.
To naturally remove blackheads and have a fairer skin, prepare a paste with equal amounts of cucumber juice and lemon juice. Apply this paste on your face and neck before taking bath. Let your skin absorb it for ten minutes. With regular use you will notice lesser blackheads and a fairer skin tone.
This is one of their beauty tips for face. I would say if you try this don’t expose your face to the sun while you have the paste on. When you expose your skin to the sun with lemon juice on it your skin gets sun spots.
