Does intermittent fasting help your skin? Myths, Facts, and What the Science Says

Intermittent fasting has become a popular trend in the wellness world, with purported benefits ranging from weight loss to cell regeneration. However, when it comes to its impact on the skin, it's important to ask whether it truly offers benefits or, on the contrary, can put its health and appearance at risk. In this article, we'll unravel the implications of intermittent fasting for facial skin and explore why the much-hyped benefits might be nothing more than a myth.

“With every break, the body seeks to renew itself; but sometimes, daily balance is the true secret to radiant skin.”

Cosmetic fasting vs. metabolic fasting: two approaches, different consequences

When we talk about "intermittent fasting for skin," it's often confused with the concept of "cosmetic fasting" or " skin dieting ." This approach involves simplifying your skincare routine at least one day a week, allowing your skin a break from potent cosmetics like retinoids or hydroxy acids. The goal is to encourage your skin to reactivate its natural functions without constant intervention, promoting its balance.

On the other hand, metabolic fasting affects the body's internal functioning and can therefore have visible repercussions on the skin. Although fasting has benefits for the metabolism, such as improved cellular function, this doesn't necessarily translate into advantages for the skin. In fact, the skin needs a constant supply of nutrients, water, and antioxidants to stay healthy, something that fasting interferes with by limiting access to these essential substances.

“Rest isn't giving up; it's knowing when to give your skin space to breathe, but without neglecting to nourish it.”

The Myth of Intermittent Fasting for Skin: What Does Your Skin Lose During Fasting?

Although some claim that intermittent fasting can improve skin, studies and clinical experience suggest that the risks may outweigh the benefits . The skin is an organ that requires a constant supply of nutrients and water to regenerate and protect itself from external aggressions. During fasting, this supply is compromised, leading to several negative effects.

  • Loss of essential vitamins and minerals: Prolonged fasting can reduce levels of vitamins A, C, and E, as well as zinc, all essential for cell repair and collagen production. Without these, the skin loses its ability to regenerate, appearing duller and more vulnerable to damage.
  • Hormonal imbalances: During fasting, insulin and cortisol (the stress hormone) levels can fluctuate. These hormonal changes can increase sebum production, triggering acne breakouts and contributing to inflammation.
  • Dehydrated and sagging skin: By reducing food and fluid intake, the skin can become dehydrated, losing elasticity and resulting in a more aged and sagging appearance.
  • Increased risk of inflammation: A lack of antioxidant nutrients during periods of fasting can increase inflammation levels in the body, exacerbating skin conditions such as rosacea and acne.

“The skin, like a garden, flourishes with daily care. Prolonged lack of care is not rest, but oblivion.”

How to maintain healthy skin without sacrificing nutrients: alternatives to fasting

The real secret to healthy skin isn't eliminating foods, but rather adopting a balanced diet that provides the nutrients necessary for cell regeneration. For those who want to maintain radiant, firm skin without resorting to fasting, there are more effective and sustainable alternatives.

  • Antioxidants and essential vitamins: A diet rich in fruits, vegetables, and healthy fats like avocados and almonds helps protect your skin against aging and sun damage. Complement these habits with facial products containing natural antioxidants.
  • Products rich in essential nutrients: We recommend incorporating treatments with ingredients like carrot oil or vitamin C , present in the Bio Protect 360 Serum . These products restore radiance and strengthen the skin's natural barrier, especially when it needs more support.
  • Revitalizing facial toner: Keeping your skin well hydrated is essential, especially when reducing your fluid intake. A toner based on floral waters, like our Fresh Flower Tonic , refreshes and prepares your skin to better absorb nutrients.

“True beauty lies in taking care of what nourishes and sustains the skin from its roots.”

Intermittent Fasting: An Enemy for Saggy Skin ?

One of the most common skin-related problems is sagging skin. Many people hope that intermittent fasting can improve skin firmness, but the reality is more complex. Without an adequate supply of collagen and antioxidants, the skin loses elasticity and appears sagging. Furthermore, the dehydration that can accompany fasting accelerates this process, resulting in a more aged appearance.

The most effective solution to combat sagging skin is to maintain a consistent skincare routine and use specific products that promote collagen production. At Såper, we suggest using the Illuminating Serum , which contains natural active ingredients to firm the skin and restore its radiance. It's also recommended to complement these treatments with natural oils, such as rosehip, to deeply nourish and prevent loss of firmness.

A holistic approach to healthy skin

Intermittent fasting may offer overall health benefits, but it's not the solution to improving facial skin. Skin needs constant care, both internally and externally, to stay healthy, radiant, and protected. Adopting a balanced approach that combines a diet rich in essential nutrients, adequate hydration, and high-quality natural products is the key to an enviable complexion.

At Såper, we promote a holistic lifestyle that respects the natural rhythms of the body and skin. Rather than relying on passing trends, we embrace ongoing care, using products made with botanical ingredients that nourish the skin from the inside out.

“Skin doesn't need less, it needs better. Caring for it is a daily act of love, where every drop counts and every nutrient contributes.”
