Applying Raw Lemon on Face? Why Dermatologist Warns You Against This Viral DIY Trend

You must have seen viral reels promoting use of raw lemon juice on your face. This DIY skincare hack promises a glowing skin and removal of acne. But before you jump into the bandwagon and try out this trend, let us warn you that lemon may not be as skincare-friendly as it seems. Today, this article will explain whether using lemon on face is good for your skin or damages the barrier. 

To understand this better, we reached out to our expert, Dr Ruben Bhasin Passi, Senior Consultant, Dermatology, CK Birla Hospital, Gurgaon.     

Can Using Raw Lemon On Face Harm Your Skin?

Dr Passi says that a slice of lemon may seem harmless, but it is natural, inexpensive and easily available in almost every kitchen. “That combination has made lemon juice a long-standing home remedy for tanning, acne marks and dark spots. But natural does not automatically mean safe for facial skin. Applying raw lemon juice directly to the face can do considerably more harm than good,” she explains.

Let us first understand why did lemon become a skincare favourite? The expert explains, “Lemons contain citric acid and vitamin C, both of which sound promising in the context of brightening. This has fuelled the idea that rubbing lemon juice on the skin can exfoliate dead cells and lighten pigmentation.”

Dr Passi continues, “The problem is that kitchen lemon juice is not the same thing as a properly formulated skincare product. A skincare product is designed with a controlled concentration, pH, stabilisers and a suitable delivery system. Fresh lemon juice has none of that precision. Therefore, the result can be unpredictable irritation, particularly when it is applied repeatedly.”

What Are The Risks of Applying Lemon Juice on Face?

Dr Passi says that one of the most important concerns of using lemon juice on the face is a reaction called phytophotodermatitis. She explains, “Certain citrus fruits contain plant compounds called furanocoumarins. When these chemicals remain on the skin and the area is exposed to ultraviolet light, they can trigger an inflammatory reaction that may resemble a burn. Symptoms may include redness, swelling, blisters, irritation and changes in skin colour.”

The expert further adds, “The reaction may not appear immediately. It can develop after exposure to sunlight and may leave behind darker patches that persist for months. Ironically, someone trying to remove pigmentation can therefore end up creating more pigmentation.”

Can Lemon Juice Treat Acne?

Addressing this, Dr Passi says that this is another common misconception. “Raw lemon juice can irritate already inflamed acne-prone skin. Irritation can damage the skin barrier and trigger inflammation. For people prone to post-inflammatory hyperpigmentation, inflammation may make marks more noticeable rather than less.”

She continues, “Irritating skincare products can themselves contribute to dark spots gentler products are recommended for people dealing with hyperpigmentation. So, the logic of 'lemon removes pigmentation because it is acidic' leaves out a crucial part of the story: skin also reacts to irritation.”

Can You Use Lemon Safely on Skin?

Dr Passi says that there is little reason to recommend applying raw lemon juice directly to facial skin. “If someone has handled lemon or other citrus fruit, the safest approach is to wash the skin thoroughly with soap and water, particularly before going outdoors. For pigmentation, properly formulated products containing ingredients such as vitamin C, azelaic acid, retinoids or other dermatologist-recommended agents provide a much more controlled approach,” she explains.

Who should be particularly careful? Shedding light on this, the expert answers, “People with sensitive skin, eczema, rosacea, active acne, a damaged skin barrier or a history of pigmentation after irritation should avoid DIY acidic treatments.”

“Pregnant women do not need to avoid lemon as a food because of this issue, but topical DIY lemon treatments are unnecessary and can irritate the skin,” adds Dr Passi.

Conclusion

Lemon belongs on the kitchen counter, not necessarily in a skincare routine. Its natural origin does not make it a gentle facial treatment. Raw lemon juice can irritate the skin and, when followed by sunlight, can trigger a reaction that leaves pigmentation behind. For someone trying to achieve clearer skin, a carefully formulated product may be considerably less exciting than a viral DIY hack, but it is also considerably more predictable.
