Toothpaste is known as one of the popular home treatments for acne. Anecdotal evidence claims that acne disappears if the toothpaste stays overnight. However, there is no scientific evidence to support this claim. In fact, if toothpaste is used to treat acne, it can do more harm than good. Shocking isn't it?
In this article, we share with you our research and scientific resources on why toothpaste may not be the right option to treat acne. We will also share alternatives that can help you deal with the problem.
Is it safe to use toothpaste for pimples? Is useful?
Toothpaste is not safe for your skin. It is formulated for teeth, not skin. Toothpaste can damage your skin for the following reasons:
- Contains Triclosan
Triclosan is an antimicrobial agent commonly used in toothpaste. However, the U.S. Food and Drug Administration (FDA) banned this chemical substance in 2017, as it may affect thyroid hormone levels ( 1 ). Triclosan can also trigger skin cancer development (such a result has been achieved when tested on animals) ( 2 ).
Even if it does not contain triclosan, toothpaste is not a safe option for your skin. There are other ingredients in toothpaste that can damage your skin:
- Sodium Lauryl Sulfate (SLS)
- sorbitol
- Sodium bicarbonate (Carbonate)
- Menthol
- Hydrogen peroxide
- Alcohol
- Essential oils
A study evaluating four different brands of toothpaste with different chemical composition found that three of this four toothpaste irritated the skin of 16 of 19 human participants. Toothpaste brands have caused mild to severe skin reactions ( 3 ).
None of the above ingredients are suitable for your skin. They can cause skin irritation. Also, while the toothpaste has a basic pH level, our skin's pH is acidic. Therefore, applying toothpaste to the skin can disrupt its natural pH, causing rashes and irritation.
Toothpaste is not a good treatment option for acne. It can dry your skin and worsen the situation instead. If you are looking for a natural solution, there are solutions that are not as risky as toothpaste:
Alternative Acne Treatment Options
1. Over-the-counter Medicines
If you experience frequent acne problems, you can try over-the-counter products (face wash, gels and creams). Try to choose OTC face washes and creams that contain the following ingredients:
- Benzoyl peroxide ( 4 )
- Salicylic acid ( 5 )
- Sulfur ( 6 )
- Tretinoin (or Retinoids) ( 7 )
While over-the-counter medicines work effectively for mild to moderate pimples, drugs with higher doses of ingredients are needed in severe cases. In such cases, consult a dermatologist.
2. Home Natural Treatment Methods
If you prefer natural home treatment options, you can try the following ingredients:
- Tea tree oil
One study found that applying 5% tea tree oil helped heal mild to moderate pimples ( 8 ). However, be careful when using tea tree oil (or other essential oils). Always dilute with a carrier oil (preferably jojoba, olive oil or sweet almond oils). Mix 2-3 drops of essential oil with a tablespoon of carrier oil.
- Aloe vera
Aloe vera extracts have anti-acne effects on your skin. It also helps moisturize your skin and stimulates collagen production ( 9 ). You can remove the gel from the leaf and apply it directly to acne.
- Probiotics
Eating and applying probiotics (kefir or yogurt) can help restore (and protect) your skin barrier function. They can also prevent acne. Preliminary studies have found that probiotic intake can inhibit the growth of P. acnes bacteria by producing antibacterial proteins ( 10 ).
Although natural remedies are safer options, it's important to test whether you have an allergy in a small area of your skin beforehand.
Chemicals in toothpaste can fight microbes in the oral cavity, but may not be effective in treating skin problems. Toothpaste can cause excessive skin dryness, itching and exacerbate existing pimples or cause new ones. Try the alternative solutions we mentioned. Consult a dermatologist.
Frequently Asked Questions
Does Colgate toothpaste help treat acne?
No. Colgate toothpaste (or any toothpaste) can make the situation worse. It can dry the skin and cause irritation.
How can I heal acne faster?
Try over-the-counter medications that contain benzoyl peroxide, salicylic acid, or sulfur. These can help reduce inflammation quickly. In more serious cases, consult a dermatologist.
