Baking soda to remove very dark stains...

Ingredients:

1 teaspoon of pure honey.

1/2 teaspoon of  baking soda (make sure the powder is very fine).

The  juice of half a fresh lemon.

Preparation and how to apply step by step:

Place half a teaspoon of  baking soda in a small bowl.

Squeeze lemon  juice onto the baking soda. You will notice an immediate effervescent reaction (foam); this is perfectly normal.

Add the teaspoon of honey and stir very well with a spatula until you obtain a smooth paste.

For nighttime use only. Wash your face with your usual soap and leave it slightly damp.
