Age spots — sometimes called liver spots or solar lentigines — are flat, darkened patches that commonly appear on areas of skin exposed to the sun over time. They often show up on the face, hands, shoulders, and arms, especially as we get older. While they are harmless, many people look for ways to reduce their appearance and achieve a more even skin tone.
Although professional treatments and commercial creams are available, some people prefer simple home remedies using ingredients already in their kitchen. One such ingredient is baking soda. In this guide, you’ll learn how baking soda may help lighten age spots, how to use it safely, and what precautions to keep in mind.
Before trying any home remedy, remember that skin types vary, and what works for one person may not work for another. If you have sensitive skin or persistent pigmentation concerns, it’s always wise to consult a dermatologist.
WHAT ARE AGE SPOTS AND WHY DO THEY FORM?
Age spots develop due to prolonged sun exposure. Over time, ultraviolet (UV) rays stimulate excess melanin production in certain areas of the skin. Melanin is the pigment responsible for skin color. When it clusters together, it forms darker patches.
Common causes include:
- Years of sun exposure
- Tanning beds
- Natural aging
- Genetics
They are typically:
- Flat and oval-shaped
- Tan, brown, or dark brown
- Painless and harmless
While they do not require medical treatment, many people choose to lighten them for cosmetic reasons.
WHY BAKING SODA IS USED FOR SKIN CARE
Baking soda, also known as sodium bicarbonate, is widely used in cooking and cleaning. In skincare, it is valued for its mild exfoliating properties.
Exfoliation Benefits
Baking soda has a fine, grainy texture that can help gently remove dead skin cells from the surface. Exfoliation may gradually reduce the appearance of pigmentation by encouraging new skin cell turnover.
pH Balancing Claims
Baking soda is alkaline. Some believe it may help balance the skin’s pH. However, it’s important to note that the skin naturally has a slightly acidic pH, and excessive alkalinity can sometimes disrupt its protective barrier.
Brightening Effect
Regular gentle exfoliation can make the skin appear brighter and more even-toned over time, which may help reduce the visibility of age spots.
It’s important to use baking soda cautiously and not overdo treatments, as overuse can lead to dryness or irritation.
BAKING SODA PASTE FOR AGE SPOTS
This is the simplest and most commonly used method.
Ingredients
- 2 teaspoons baking soda
- Small amount of water (enough to form a thick paste)
Instructions
- In a small bowl, mix baking soda with a few drops of water.
- Stir until a thick paste forms.
- Apply gently to the age spots using clean fingers. Avoid scrubbing harshly.
- Leave on for about 3–5 minutes. If you have sensitive skin, begin with 2 minutes.
- Rinse thoroughly with lukewarm water.
- Pat dry with a soft towel.
- Apply a gentle moisturizer afterward.
Frequency
Use 2–3 times per week. Observe how your skin responds and reduce frequency if dryness or irritation occurs.
Consistency is key. Gradual improvement may take several weeks.
BAKING SODA AND LEMON JUICE METHOD
Lemon juice is often paired with baking soda because of its natural vitamin C content and mild brightening properties.
However, lemon juice can increase sun sensitivity, so this method requires extra caution.
Ingredients
- 2 teaspoons baking soda
- 1 teaspoon fresh lemon juice
Instructions
- Combine baking soda and lemon juice in a small bowl.
- The mixture will fizz briefly — this is normal.
- Once the fizzing slows, apply gently to the affected areas.
- Leave on for no longer than 5 minutes.
- Rinse thoroughly with lukewarm water.
- Apply moisturizer immediately after.
Important Sun Protection Step
If you use lemon juice on your skin, always apply sunscreen before going outdoors. Lemon can make the skin more sensitive to UV rays.
Frequency
Use once per week to test tolerance. Overuse may lead to irritation.
HOW LONG DOES IT TAKE TO SEE RESULTS?
Home remedies typically work gradually. You may begin noticing subtle lightening after several weeks of consistent use.
Results depend on:
- Skin type
- Depth of pigmentation
- Frequency of use
- Sun protection habits
Baking soda is not a miracle solution, and deeper age spots may require professional treatment.
THE IMPORTANCE OF SUN PROTECTION
No matter which method you use, protecting your skin from further sun damage is crucial.
Always:
- Apply broad-spectrum sunscreen daily
- Wear protective clothing
- Limit midday sun exposure
- Reapply sunscreen every two hours outdoors
Without sun protection, age spots may darken again, and new ones may form.
PRECAUTIONS BEFORE USING BAKING SODA ON SKIN
Patch Test First
Before applying to visible areas, test on a small patch of skin. Wait 24 hours to check for redness or irritation.
Avoid Broken or Sensitive Skin
Do not apply baking soda to irritated, inflamed, or broken skin.
Do Not Overuse
Using baking soda too frequently may strip natural oils and weaken the skin barrier.
Moisturize After Every Treatment
Hydration helps maintain skin balance and prevent dryness.
Discontinue If Irritation Occurs
If you notice redness, burning, or peeling, stop use immediately.
WHEN TO SEE A DERMATOLOGIST
Consider professional advice if:
- Spots change in size, shape, or color
- Pigmentation spreads rapidly
- Home remedies cause irritation
- You want faster or more dramatic results
Dermatologists offer treatments such as chemical peels, laser therapy, and prescription creams.
TIPS FOR SAFER RESULTS
Start slowly. Use treatments sparingly at first.
Keep treatments short. Never exceed recommended time limits.
Hydrate well. Drink water and use moisturizer regularly.
Avoid mixing with multiple active ingredients.
Apply sunscreen daily, even indoors near windows.
Be patient. Natural remedies require consistency and time.
Use gentle circular motions when applying — do not scrub aggressively.
Limit lemon-based treatments to nighttime use.
Frequently Asked Questions

Final Thoughts
Using baking soda as a home remedy for age spots can be a simple and affordable approach for those seeking gradual skin brightening. Its exfoliating properties may help fade pigmentation over time when used carefully and consistently.
However, it’s important to manage expectations. Baking soda is not a guaranteed cure, and overuse can irritate the skin. Gentle application, proper hydration, and diligent sun protection are essential for safe results.
For persistent pigmentation or dramatic improvements, professional skincare treatments may provide more reliable outcomes. Always prioritize skin health over quick fixes, and treat your skin with patience and care.
