Every few weeks, social media serves up a new beauty hack. The latest? Washing your face with baking soda. While it may seem harmless—and even budget-friendly—this trend is far from skin-friendly, says Dallas dermatologist Elizabeth Houshmand, MD.
Why Baking Soda Doesn’t Belong on Skin
Your skin has a natural protective barrier, called the acid mantle, with a slightly acidic pH of 4.5–5.5, explains Dr. Houshmand. "Baking soda, by contrast, is very alkaline, with a pH around 9," she says. "Using it on your face disrupts that delicate balance."
The result? Dryness, irritation, redness and an impaired barrier that leaves your skin vulnerable to breakouts and flare-ups. "What sounds like a quick glow hack can actually cause long-term problems," she says.
“But It Is Natural…”
Just because an ingredient comes from your kitchen doesn’t mean it belongs in your skin-care routine. "Take lemon juice—it may be natural, but its high acidity can disrupt your skin’s delicate barrier, leading to irritation and sensitivity," says Dr. Houshmand. "Baking soda is another common culprit. While it’s a pantry staple, its high pH can throw your skin off balance. When it comes to skin care, natural doesn’t always mean gentle—or safe."
Safer Ways to Exfoliate + Glow
If the appeal of baking soda is its exfoliating effect, try these proven, dermatologist-approved alternatives instead:
- Gentle chemical exfoliants (like glycolic or lactic acid) that smooth without stripping.
- Mild physical scrubs with rounded particles, designed specifically for skin.
- Non-foaming cleansers that clean while protecting your barrier.
And don’t forget the basics, Dr. Houshmand stresses: Daily sunscreen and a moisturizer suited to your skin type are still the most powerful glow-givers.
The Bottom Line
Social media hacks can be fun, but they’re not all safe—or effective. "Washing your face with baking soda can leave you with irritation, not radiance," says Dr. Houshmand. "Protecting your skin barrier will always be the smartest beauty trend to follow."
