Baking soda is not a good treatment for dark spots, wrinkles, or under-eye dark circles. It is alkaline and can irritate the skin, disrupt its protective barrier, and make pigmentation worse—especially on sensitive skin around the eyes.
Instead:
-
Dark spots: Use daily broad-spectrum SPF 30–50 and consider products containing azelaic acid, vitamin C, or niacinamide.
-
Wrinkles: Daily sunscreen and a retinoid/retinol are better-supported options.
-
Dark circles: The cause matters—genetics, pigmentation, allergies, shadows, and thin skin can all contribute. Gentle skincare and sunscreen may help; persistent circles can be discussed with a dermatologist.
-
Avoid putting baking soda under or around your eyes. Also avoid harsh scrubbing, which can worsen irritation and pigmentation.
If you tell me your age and whether the dark spots are brown, black, or reddish, I can suggest a simple routine using commonly available products.
