3-Day Use Guide and Precautions

Ethan Hartwell | March 30, 2026

To treat acne, people typically rely on fairly heavy treatments, including medications with bothersome additives. But a natural alternative was brought to our attention by a loyal reader of consoGlobe.com.

We have not tested it, and this cure requires precautions. But on social media and in certain “detox” circles, a method keeps resurfacing: three days based on apples, with a parallel routine (castor oil). The stated goal: to give the digestive system a rest, support elimination, and improve skin condition.

Important: this protocol resembles a restrictive diet / partial fast. It is not suitable for everyone, and should never replace medical supervision in cases of persistent, inflammatory, or painful acne.

Treating acne with apples: the principle of this 3-day cure

If you’re frustrated by acne despite numerous attempts, this method may intrigue you. It’s short (3 days), fairly simple… but also quite demanding. The idea is to choose a calm period, with no intense exercise or travel, and to never exceed three days.

Here’s how the cure unfolds:

  • Eat only apples (up to 10 per day, ideally organic).
  • Apply a topical treatment with castor oil in the evening (on the pimples).
  • Drink only water, in sufficient quantities.

Apple cure: who should avoid it? (read before you start)

Helpful reminder: a highly restrictive diet can cause fatigue, irritability, headaches, low blood pressure, digestive issues… and occasionally a transient flare-up of pimples in some people (inflammatory reactions, stress, hormonal fluctuations).

Against acne: 10 apples a day… how to do it concretely?

The first step is to eat up to ten apples per day and nothing else. It may sound surprising, but this format is often presented as a “digestive reset”: apples contain water, fiber, and polyphenols (some of which are antioxidants).

Practical tip: rather than forcing 10 apples, listen to your body. The idea is to spread them throughout the day:

  • 2 apples on waking
  • 2 apples mid-morning
  • 3 apples in the afternoon
  • 2 to 3 apples in the evening

If you have a sensitive stomach, favor apples at room temperature, chew slowly, and avoid drinking too much at once (that can worsen bloating).

Which apple variety should you favor?

For this cure, certain recommendations recur: favor Red Delicious, preferably organic to limit pesticide exposure.

Fasting to heal acne: 3 days, but not more

Eating only apples for 3 days generally triggers:

  • A reduction in fat and protein intake, which can “ease” digestion.
  • An effect on the bowel movement thanks to the fiber content.
  • A sensation of hunger: the body will draw on its reserves (with possible fatigue).

Fighting acne: castor oil and a “no-aggression” skin routine

During the nights of the 3-day cure, it’s advised to apply a small amount of castor oil on each pimple (locally only, not on the entire face if you have oily skin).

Gently tap the oil, spreading it evenly to cover the pimple and its border.

The aim: support the skin barrier, avoid picking, and limit the contact between impurities and the lesions.

The right move: how to apply castor oil?

  • Cleanse your face with a gentle product (no exfoliating scrub).
  • Pat dry, don’t rub.
  • Apply a micro-droplet on each pimple.
  • Leave on overnight.

Some clarifications to ensure the cure goes smoothly

1) Drink enough water (but not to excess)

The cure calls for drinking water. Many versions suggest 3.5 to 4 L/day… which can be excessive depending on the person.

Practical approach: drink regularly throughout the day, and adjust to your thirst. Very pale urine all the time can signal excess.

2) Sleep: your number one anti-acne treatment

Stress and lack of sleep often worsen acne. Aim for 8 hours of sleep, avoid screens late at night, and establish a calm routine (warm shower, reading, breathing exercises).

How to maintain the results after the cure?

If the cure yields an improvement (even mild), the key is what happens after. Acne is multifactorial (hormones, stress, microbiome, genetics…). To limit breakouts:

  • Continue to drink enough water
  • Keep a consistent sleep pattern
  • Limit ultra-processed foods and excess quick sugars
  • Avoid touching your pimples
  • Adopt a simple skincare routine (gentle cleanser + light moisturizer)

Finally, if acne is inflammatory or leaves marks, it’s best to consult a dermatologist: there are effective solutions, including natural options, but also medical ones when necessary.
