Viral Hack Checked: Baking Soda Face Scrub for Glowing Skin?
Verdict: Risky. Baking soda (meetha soda) is strongly alkaline, while healthy facial skin is mildly acidic, so scrubbing with it strips the skin’s protective barrier. The usual result is redness, tightness, flaking and, for many people, more breakouts, not a glow. A gentle cleanser, a moisturiser and daily sunscreen do far more.
The short version
- The hack: baking soda mixed with water, lemon or face wash and rubbed on the face as a scrub or mask.
- Verdict: Risky for regular use, and worst for dry, sensitive or acne-prone skin.
- Why: a pH around 8 to 9 against skin that sits near 5, plus gritty crystals.
- The glow you see: short-lived; the scraped surface reflects light for a day.
- Do instead: gentle cleanser, moisturiser, sunscreen, and a mild exfoliant no more than twice a week.

Why would a kitchen raising agent end up on so many faces? It’s cheap, it’s sitting in every kitchen next to the haldi and the zeera, and it feels like it’s doing something, because the skin tingles, turns pink and feels squeaky clean after, which most of us were raised to read as a sign that the dirt is finally gone. That feeling is the problem. This check in our Viral Hacks Checked series explains what baking soda does to facial skin, why the “glow” fades so fast, and a gentler routine that actually brightens.
Why baking soda and skin don’t get along
ELI5 first. pH is a scale from 0 to 14 that measures how acidic or alkaline something is. Lemon juice is very acidic, pure water is neutral at 7, and baking soda dissolved in water is alkaline, roughly 8 to 9. The outer layer of healthy skin sits on the acidic side, around 4.5 to 5.5. Skin experts call this the acid mantle.
That slight acidity isn’t a random detail, because it helps the skin’s own enzymes build and hold the fats that seal the barrier, and it keeps harmful germs in check while the friendly ones that live on every healthy face carry on doing their quiet work. Push the surface up towards alkaline again and again and those systems slow down. Water escapes. Irritants get in. The skin reacts.
Then add friction. Baking soda crystals are small but hard and uneven, and when they’re rubbed in circles over the cheeks and nose they scrape away at the very top layer of skin, which is exactly the thin, fragile part that was holding moisture in to begin with.
Squeaky clean is the sound of a skin barrier being stripped.
What people actually get: the before and after nobody posts
- Redness and stinging within minutes, sometimes a burning feeling.
- Tight, flaky patches a day or two later, especially around the nose and mouth.
- More breakouts, because irritated skin can produce more oil and inflammation.
- Dark marks on brown skin, where irritation often leaves post-inflammatory darkening.
- Sensitivity to products that never stung before.
The same thing happens under the arms with baking soda deodorants, which is why so many people get rashes from them. Our piece on baking soda deodorant and skin irritation explains that side of it.
Myth: baking soda opens and cleans out pores
Pores don’t open and shut like doors, whatever the steaming videos suggest, and baking soda doesn’t reach inside them in any useful way, because it’s mostly dissolved and rinsed away within the minute or so it spends on the face. It clears surface oil, which makes pores look smaller for an hour, and it can leave tiny scratches around them. For pores that look large, the steady basics (gentle cleansing, sunscreen and, for some, a salicylic acid or retinoid product) matter much more, as our guide to enlarged pores and what actually helps lays out.
Myth: lemon plus baking soda balances out
The viral combo mixes acidic lemon with alkaline soda so it fizzes. That fizz is the two cancelling each other into a salt solution and carbon dioxide, so the “balance” mostly means both ingredients have stopped being what they were, except that any leftover lemon on the face still carries a burn risk in sunlight (phytophotodermatitis) and leftover soda still scrubs. It’s a science-fair volcano on your cheeks. Not skincare.
Did you know? Baking soda is so reliably alkaline that it’s used in labs and kitchens to neutralise acid spills, which is exactly why it upsets skin that depends on being slightly acidic.
A gentler routine that actually brightens
- Cleanse: lukewarm water and a gentle, fragrance-free cleanser, morning and night. Massage for 30 to 60 seconds, rinse, pat dry.
- Moisturise: a pea-to-almond-sized amount of plain cream or lotion while skin is still slightly damp.
- Sunscreen every morning: broad spectrum, SPF 30 or more, two finger-lengths for the face. This is the biggest single step for even, bright-looking skin.
- Exfoliate gently, if at all: once or twice a week at most. Options: a soft washcloth with light pressure, or a mild leave-on exfoliant (lactic, glycolic or salicylic acid at the strength on the pack) introduced every third night.
- Kitchen option: if you like a home pack, 1 tablespoon of besan with 1 to 2 tablespoons of plain yoghurt or milk, left for 10 minutes and rinsed off with no rubbing, is far kinder than soda. Patch test first.
- Give it time: skin renews over about 4 weeks, so judge any routine after a month, not a morning.
Already used baking soda and now it stings?
Stop all scrubs, acids, retinoids and fragranced products for 1 to 2 weeks, and meanwhile wash with lukewarm water and a mild cleanser, moisturise twice a day, and wear sunscreen. A thin layer of petroleum jelly over very raw patches at night helps the barrier rebuild. Most mild irritation settles within a couple of weeks.
Get help if the skin blisters, oozes, swells or cracks; if burning or pain lasts beyond a day; if there’s spreading redness, crusting or fever; or if irritation hasn’t settled after 2 weeks of a plain routine. Anyone with eczema, rosacea or very sensitive skin should keep baking soda off the face entirely. Acids and retinoids carry pregnancy cautions, so pregnant or breastfeeding readers should ask a doctor before starting them. If you use prescription skin creams, ask the prescriber before adding any exfoliant, and never swallow baking soda as a skin remedy.
Baking soda on the face: common questions
Is baking soda good for your face?
No. It’s alkaline, while healthy facial skin is slightly acidic, so it strips the skin barrier and often causes redness, dryness and breakouts.
Does baking soda remove blackheads?
It may scrape off some surface oil for a short time, but it doesn’t clear pores properly and the irritation can make things worse. Salicylic acid products, used as the pack says, are a better choice.
Can baking soda lighten dark spots or tan?
No. It doesn’t fade pigment, and on brown skin the irritation it causes can leave new dark marks, whereas daily sunscreen is what helps tan and dark spots fade over time.
What is the pH of baking soda compared with skin?
Baking soda in water is around pH 8 to 9, while the skin’s surface sits roughly between 4.5 and 5.5. That gap is why it disrupts the skin’s natural balance.
Is a baking soda and lemon face mask safe?
It isn’t a good idea. The fizz neutralises both, leftover soda still scrubs, and leftover lemon can burn and darken skin in the sun.
How often can baking soda be used on the face?
Dermatologists generally advise against using it on the face at all; if you want exfoliation, a mild product once or twice a week is safer.
Is baking soda safe for acne?
No. Irritation from baking soda can trigger more breakouts and dark marks. Mild acne usually does better with benzoyl peroxide or adapalene used as the pack says, and ongoing acne needs a doctor.
What can be used instead of a baking soda scrub?
A gentle cleanser, moisturiser and daily sunscreen are the base. Add a soft washcloth or a mild acid exfoliant once or twice a week, or a besan and yoghurt pack rinsed without rubbing.
How long does skin take to recover after a baking soda scrub?
Mild redness and tightness usually settle within a few days to 2 weeks with a plain, gentle routine. Blisters, oozing or pain need a doctor.
Is baking soda safe on the body, like elbows and knees?
Thicker skin tolerates it a little better, but it’s still harsh and drying. A moisturiser with urea or lactic acid softens rough elbows and knees more gently.
