Why Mixing Lemon and Toothpaste at Night is Trending – What You Should Know

The internet is full of home hacks and natural remedies, and one trend that has recently gained attention is mixing lemon juice and toothpaste and using it once a night. Enthusiasts claim it can improve skin health, whiten teeth, and even eliminate acne. But how effective is this practice, and is it safe? Let’s explore the facts.

What Happens When You Mix Lemon and Toothpaste?

Toothpaste often contains ingredients like baking soda, hydrogen peroxide, triclosan, menthol, and fluoride. These components are designed for oral hygiene but are sometimes repurposed in DIY beauty routines.

Lemon juice is rich in vitamin C and citric acid, known for its bleaching and antibacterial properties. When combined with toothpaste, it’s believed the mixture can:

• Lighten dark spots on the skin
• Dry out pimples
• Reduce acne scars
• Whiten teeth

How to Use It – The Common Method

For Acne and Dark Spots:

1. Mix a teaspoon of toothpaste (preferably white paste, not gel) with a few drops of fresh lemon juice.
2. Apply a small amount of the mixture to the affected area (avoid full-face application).
3. Leave it on for 10–15 minutes.
4. Rinse thoroughly with lukewarm water.
5. Repeat nightly if your skin doesn’t show signs of irritation.

For Teeth Whitening:

1. Combine a pea-sized amount of toothpaste with a few drops of lemon juice.
2. Brush your teeth gently for no more than 2 minutes.
3. Rinse thoroughly and avoid eating for 30 minutes after brushing.
4. Use only once or twice a week to avoid enamel damage.

Is It Safe?

While both lemon and toothpaste are effective in their own fields, combining them—especially for skin use—requires caution.

Pros:

• Lemon offers antibacterial and brightening effects.
• Toothpaste can temporarily dry acne and reduce oiliness.
• Affordable and easily accessible ingredients.

Cons:

• Lemon is highly acidic and can damage skin and tooth enamel.
• Toothpaste is not formulated for skin use and may cause dryness, redness, or irritation.
• Overuse can lead to burns, increased sensitivity, or long-term skin damage.

What Experts Say

Dermatologists often warn against using harsh acidic substances like lemon directly on the skin, especially in combination with other strong ingredients. While some people report benefits, results vary greatly, and misuse can do more harm than good.

Final Thoughts

If you’re looking for a natural boost in your beauty routine, mixing lemon and toothpaste once a night might provide some short-term results—but proceed with caution. Always do a patch test and never use this method on broken or sensitive skin. For teeth, use this combo sparingly to avoid enamel erosion.
