Here’s the more detailed reality behind that claim:
Why a “3-minute” trick is unlikely to remove age spots
True age spots—also called solar lentigines—are areas of excess pigment caused largely by cumulative UV exposure. They commonly appear on the backs of the hands.

The pigment isn’t simply sitting on the surface of your skin, so wiping, rubbing, or applying a household ingredient for three minutes generally cannot remove the underlying pigmentation. Dermatologists note that creams and lotions used to fade age spots typically require weeks to months of consistent use.

What can happen in 3 minutes?
A trick could make your hands appear brighter temporarily. For example:
Removing surface dirt or dead skin can make skin look more even.
Moisturizer can temporarily make dry, textured skin look smoother.
Some cosmetic products can immediately camouflage pigmentation.
Exfoliation can temporarily change the appearance of the skin’s surface.
But that’s different from actually reducing the melanin responsible for an age spot.
What actually has evidence behind it?
For gradual fading, dermatology sources mention ingredients such as retinoids, glycolic acid, kojic acid, vitamin C and azelaic acid, depending on the cause and the individual’s skin.

Professional treatments—including laser/IPL, cryotherapy, chemical peels and microdermabrasion—can work faster, but they still aren’t a three-minute, zero-effort home remedy and can have side effects such as irritation or changes in pigmentation.

Most importantly, sun protection matters. A broad-spectrum SPF 30+ on the backs of your hands can help prevent additional UV damage and new spots.

One important warning
Don’t assume every dark spot is an age spot. A spot that is new, black, rapidly changing, irregular, multicolored, or bleeding should be examined by a doctor because some skin cancers can resemble age spots.

So if your mom’s trick involves something like lemon juice, baking soda, toothpaste, vinegar, hydrogen peroxide, or another household ingredient, tell me exactly what she uses. I can break down what it is supposed to do, whether there’s evidence for it, and whether it could damage the skin.
