That sounds like a viral “miracle blemish remover” claim. Be careful about adding a household ingredient or medicine to your regular face cream—some combinations can cause irritation, burns, allergic reactions, or make dark marks worse.
For common facial blemishes:
-
Acne: benzoyl peroxide or salicylic acid can help.
-
Dark spots left after acne: daily broad-spectrum sunscreen and ingredients such as azelaic acid can help fade them.
-
Melasma or persistent pigmentation: may need a dermatologist’s assessment and a targeted treatment.
Avoid putting lemon juice, baking soda, toothpaste, bleach, or undiluted essential oils on your face. They can damage the skin barrier.
If you tell me what the headline says to add to the cream, I can tell you whether that ingredient is safe, whether it actually has evidence behind it, and how it should be used.
