Baking Soda on the Face: Benefits, Risks, and How to Use It Safely
Baking soda is a common kitchen ingredient, and social media has turned it into a popular DIY skincare remedy. You may have seen claims that baking soda can brighten skin, remove blackheads, reduce acne, or even make wrinkles disappear.
But before putting it on your face, there’s an important question to ask:
Is something that’s useful in the kitchen necessarily good for your skin?
Not always.
What can baking soda actually do?
Baking soda, or sodium bicarbonate, is mildly alkaline and has gentle abrasive properties.
Because of this, some people use it as a homemade exfoliant or cleanser.
However, facial skin has a naturally acidic protective barrier. Applying alkaline substances can interfere with that barrier and potentially cause dryness or irritation.
So while baking soda may make skin temporarily feel smoother, that doesn’t mean it’s improving the health of your skin.
What about acne and blackheads?
You may see DIY recipes combining baking soda with water, honey, lemon juice, or toothpaste and claiming that the mixture “pulls out” impurities.
There’s little reason to rely on these homemade treatments.
Baking soda can be irritating, especially if it’s rubbed vigorously against the skin. Irritation can lead to redness, dryness, burning, and worsening sensitivity.
For acne-prone skin, products specifically formulated with ingredients such as salicylic acid or benzoyl peroxide generally have much stronger evidence behind them.
Could it brighten dark spots?
Baking soda doesn’t safely erase pigmentation.
Aggressive scrubbing can actually irritate the skin and potentially make discoloration more noticeable, particularly in people prone to post-inflammatory hyperpigmentation.
If you’re concerned about dark spots, a gentle skincare routine and daily sunscreen are much better places to start.
What if you still want to try it?
The safest option is not to use baking soda as a regular facial treatment.
If you’re considering any new DIY ingredient, patch-testing a small area first is a sensible precaution. Don’t apply it to broken, irritated, sunburned, or freshly shaved skin.
And never combine irritating ingredients simply because a viral recipe claims they work better together.
Avoid the lemon-and-baking-soda trend
One particularly common DIY recipe combines baking soda and lemon juice.
This isn’t a good facial treatment.
Lemon juice can irritate the skin and make it more sensitive to sunlight. Combined with aggressive scrubbing, the result can be redness, irritation, or worsening pigmentation.
Better alternatives for healthy-looking skin
If your goal is smoother, healthier-looking skin, keep things simple:
- Use a gentle cleanser.
- Moisturize regularly.
- Wear broad-spectrum sunscreen with SPF 30 or higher.
- Choose skincare ingredients based on your specific concern.
- Introduce new products gradually.
- Avoid harsh scrubbing.
For persistent acne, eczema, unusual rashes, or significant skin discoloration, a dermatologist can recommend treatments appropriate for your skin.
The bottom line
Baking soda may be inexpensive and useful around the house, but that doesn’t make it an ideal facial skincare ingredient.
A DIY treatment that leaves your skin feeling “squeaky clean” may actually be stripping away protective oils.
Your skin doesn’t need to be scrubbed into submission.
Gentle, consistent skincare is usually a better strategy than a viral kitchen remedy.
