A weakened skin barrier may lead to:
dryness
stinging
burning
redness
itching
tightness
flaking
more sensitivity
worsening irritation
more visible discoloration after inflammation
This is why baking soda is not usually recommended as a regular facial treatment. It may seem like a natural remedy, but “natural” does not always mean gentle.
Some people may tolerate a very diluted, short-contact use on less sensitive areas, but many people should avoid it altogether, especially those with sensitive skin, eczema, rosacea, acne-prone skin, dark marks after inflammation, or any irritation around the eyes.
Should You Use Baking Soda Under the Eyes?
It is better not to use baking soda under the eyes. The risk of irritation is too high, and the possible benefit is too low.
Under-eye darkness is usually not caused by dirt sitting on the surface of the skin. It may come from pigmentation, shadows, blood vessels, allergies, lack of sleep, or thin skin. Baking soda does not solve those causes.
If baking soda gets into the eyes, it can cause irritation. Even if it does not enter the eyes, it may dry or irritate the delicate skin around them.
A safer under-eye routine is gentle: hydration, sun protection, enough sleep, allergy control when needed, and products made specifically for the eye area.
Safer Ways to Help Dark Spots Fade
If dark spots are your main concern, the most important step is sunscreen. Without sunscreen, dark spots often return or deepen. The American Academy of Dermatology recommends consistent sun protection for dark spots, including reapplying sunscreen and wearing protective clothing when outdoors.
A simple routine can include:
gentle cleanser
moisturizer
broad-spectrum sunscreen every morning
avoid picking or scratching the skin
use brightening ingredients slowly and carefully
Ingredients often used for uneven tone include niacinamide, vitamin C, azelaic acid, retinoids, licorice extract, kojic acid, and gentle exfoliating acids. These should be introduced gradually, especially if your skin is sensitive.
If the dark spots are deep, spreading, changing, or caused by melasma, acne scars, or inflammation, a dermatologist can recommend stronger treatments.
