Soap + Cornstarch + Baking Soda: A Popular DIY Trick for Smoother, Fresher-Looking Skin
A simple blend made with soap, cornstarch, and baking soda has gone viral on social media. While this is not a medical treatment and doesn’t replace dermatologist-recommended skincare, many people use it as a quick, at-home option to help the skin feel cleaner, softer, and temporarily brighter.
Below is what each ingredient does, plus a safer way to prepare and use the mixture.
Why This DIY Mixture Is So Popular
Mild (Neutral) Soap
- Helps cleanse the skin by removing dirt, sweat, and excess oil.
- A gentle, fragrance-free soap is often preferred to reduce the risk of irritation.
Cornstarch (Maicena)
- Known for its fine, silky texture, which can make skin feel smoother and more “velvety.”
- Can help absorb oil and reduce shine without feeling as harsh as stronger drying ingredients.
Baking Soda (Sodium Bicarbonate)
- Acts as a mild physical exfoliant, helping lift away some dead skin cells.
- Must be used with extra caution because it’s alkaline and may disrupt the skin’s natural pH if overused, leading to dryness or irritation.
How to Make It (Gentler, More Skin-Friendly Version)
Ingredients
- 1 teaspoon cornstarch
- A very small pinch of baking soda (use minimal amount)
- 1 tablespoon mild liquid soap (or lightly soapy water)
- A few drops of water, as needed for texture
Preparation Steps
- Combine the cornstarch and a tiny pinch of baking soda.
- Add the mild liquid soap and stir until you get a smooth paste.
- If it feels too thick, mix in a few drops of water until spreadable.
How to Use It Correctly
- Cleanse your face first and pat dry.
- Apply a thin layer, avoiding the eye area and lips.
- Leave it on for 5–10 minutes only.
- Rinse with lukewarm water.
- Finish with a moisturizer to help prevent dryness.
Recommended frequency: no more than once per week, since baking soda can irritate skin or throw off pH balance when used too often.

Benefits Commonly Reported by Users
- Skin feels softer and smoother
- A cleaner or brighter appearance (temporary)
- Less oiliness and shine, especially for oily skin types
- Light exfoliation effect
Important Safety Tips
- Avoid this method if you have very sensitive skin, dermatitis, rosacea, or severe acne.
- Do not use it on the same day as other exfoliants (physical scrubs, acids like AHA/BHA, retinoids).
- Always do a patch test (for example, on your inner arm) before applying to your face.
Final Warning
DIY skincare remedies like this may offer short-term cosmetic results, but they are not a substitute for professional dermatology care. If you experience irritation, ongoing discoloration, breakouts, or persistent skin concerns, it’s best to consult a dermatologist before trying any homemade mixture.
