5 Things You Should Never Put On Your Face →

July 10, 2026

When it comes to skincare, knowing what to avoid is just as crucial as knowing which products to use. The internet is brimming with DIY skincare recipes, remedies, and tutorials for nearly every skin concern imaginable. While some of these methods are tried and true (and even dermatologist-approved), others can do more harm than good.

If you rely solely on online skincare tips instead of expert advice, you might be disappointed with the results. With the abundance of beauty hacks available online, many of these tips may not be suitable for your individual skin type and concerns. At worst, you run the risk of seriously harming your skin.

To protect the health and safety of your skin, here are five things you should never apply to your face.

Lemon Juice: I can understand the logic behind using lemon juice for skin care. It’s rich in vitamin C, which can brighten the skin and reduce fine lines. However, lemon juice is highly acidic and can irritate the skin, even when diluted with water. There’s also the risk of developing phytophotodermatitis, a skin reaction triggered by exposure to certain chemicals in plants and fruits under sunlight or ultraviolet light. In severe cases, lemon juice can cause chemical burns and post-inflammatory hyperpigmentation, resulting in dark spots that are tough to fade.

Instead, opt for a stabilized vitamin C serum. These formulations effectively deliver the brightening and antioxidant benefits of vitamin C in a controlled and skin-friendly manner. They are often combined with other beneficial ingredients, such as ferulic acid or vitamin E, to enhance their efficacy and stability.

Apple Cider Vinegar: One of the most prevalent misconceptions about skincare is that natural ingredients are always superior. However, certain natural ingredients can actually cause serious skin problems, and apple cider vinegar (ACV) is one of the most notorious offenders. While ACV may have some potential health benefits, its caustic, irritating, and acidic nature makes it unsuitable for use on the skin. According to experts, applying ACV to the skin can lead to burns, scars, blemishes, and hyperpigmentation.

You might have heard of apple cider vinegar being used as a facial toner, but it’s better to opt for one of the many toners and serums available on the market. Instead of ACV, consider using alpha-hydroxy acid (AHA) solutions like lactic acid or polyglutamic acid (PGA).

Toothpaste: I must confess that I was once a victim of this myth, thanks to all the teen magazines I read when I was younger. While it may seem like toothpaste dries out a pimple, it actually irritates your skin. Toothpaste contains harsh ingredients like menthol, baking soda, alcohol, and strong detergents, which are formulated for teeth, not the delicate skin on your face. These ingredients strip moisture, inflame the skin, and can cause significant dryness, flaking, and even chemical burns around the pimple. This not only prolongs the healing process but also increases the risk of noticeable scarring.

Instead, opt for a targeted spot treatment containing salicylic acid or benzoyl peroxide. Salicylic acid gently exfoliates inside the pore, clearing blockages, while benzoyl peroxide effectively kills acne-causing bacteria. Both treatments are far more effective and less damaging than toothpaste, promoting faster healing without the adverse side effects.

Coconut Oil: Coconut oil may evoke the scent of summer, but it’s a pore-clogging nightmare. Coconut oil, being highly comedogenic, has a strong tendency to block pores. Its high concentration of saturated fatty acids forms a film on the skin’s surface, trapping dead skin cells and sebum. This can lead to breakouts, particularly for those with acne-prone or oily skin.

Instead of comedogenic oils, opt for non-comedogenic alternatives like squalane and jojoba oil. These oils offer exceptional hydration and nourishment without the risk of clogging pores, making them safer choices for facial moisturizing.

Baking Soda: Baking soda may be a versatile kitchen ingredient, but it should be kept away from your face due to its alkaline nature. Remember, your skin tends to have a naturally acidic pH. Using it as a natural cleanser or mask can disrupt your skin’s pH balance and remove its protective oil barrier. This can disrupt the natural balance of bacteria on your skin’s surface, making it more prone to infections and breakouts.

Instead of using baking soda to purify pores and reduce acne, consider performing a double cleanse followed by a gentle exfoliant that won’t disrupt your protective oil barrier. You may also want to consider using a clay mask once or twice a week to keep on top of areas of your face that are prone to congestion.

Final Thoughts

When your skin is giving you trouble, it can be tempting to reach for a quick fix, especially if the solution is as close as your kitchen. But not all ingredients commonly found at home are good for your skin. While they may seem harmless, natural home remedies can cause chemical burns, irritation, and skin damage. Instead of making your skin a test subject, stick to skincare products that are lab-tested and proven to work.

But while many skincare trends are easy to ignore, skin cycling may be one trend that’s worth a second look.
