Doctors Explain Why Beauty Sleep Is Good For Your Skin

Written by Ramona Sinha

A good night’s sleep can make you feel fresh and rejuvenated. If you take a closer look, you realize that your face looks fresh, bright, and glowing. Beauty sleep is not a myth. Your body keeps working even after you have shut your eyes. It repairs and heals itself during the night so that you wake up looking refreshed. This article takes a deep dive into the relationship between sleep and skin and explains why beauty sleep is important. Read on.

What Is Beauty Sleep? What Is The Science Behind It?

“Beauty sleep is when your skin takes the time to heal itself from any damage done during the day,” says Dr. Stacy Chimento, board-certified dermatologist. She adds, “When the body enters deep sleep, our muscles relax, improving blood flow and collagen rebuilding. It further activates the recovery mode and produces human growth hormone (HGH) and melatonin (a hormone released by the pineal gland at night). These hormones create new cells that help heal our skin from inside out, even beyond the epidermis.”

Sleep influences cognitive, behavioral, and physiological functions and has a crucial impact on your long-term health. Studies consider beauty sleep crucial for improved facial and physiological appearance. Sleep-deprived people appear fatigued and unhealthy as they usually have red and swollen eyes, dark circles, paler skin, and prominent wrinkles and fine lines (1).

There are multiple other ways that sleep affects our skin. According to board-certified dermatologist Dr. Erum Ilyas, “Lack of proper sleep impairs skin hydration and leads to reduced elasticity and opportunity for DNA-repair mechanisms.” The next section explores all aspects of how sleep affects the skin.

How Does Sleep Affect Your Skin?

Insufficient sleep can:

  • Affect Skin Hydration Levels: According to a study on 22 Korean women, poor sleep quality reduces skin moisture levels and increases sebum production. The researchers observed that sleep deprivation reduced glow, transparency, and elasticity (2).
  • Cause Skin Aging: A study revealed that lack of proper sleep increased the signs of aging, such as fine lines, hyperpigmentation, skin sagging, and dryness (3).
  • Cause Breakouts: Sleep deprivation causes stress and increases the cortisol levels in your body (4). Stress and excess cortisol levels stimulate the sebaceous glands, increasing excess sebum production, leading to acne and breakouts (5).

Getting proper sleep can prevent all these harmful effects on your skin and keep it healthy. Some of the benefits of beauty sleep include:

1. Fewer Wrinkles

When you sleep, an integral part of your body’s repair process is making new collagen that keeps your skin taut and prevents sagging. Moreover, while you are asleep, the body repairs the skin barrier and all signs of environmental damage. These internal processes keep your skin youthful (1).

2. Glowing Skin

Sleep is the energy boost your body needs every day. Proper sleep helps prevent transepidermal water loss, maintains skin hydration levels, and keeps it plump, healthy, and glowing.

3. Less Puffy Eyes

Not getting enough sleep or chronic sleep deprivation can give you dark circles or puffy bags under your eyes. According to Dr. Stacy Chimento, “By getting a proper sleep, you have better chances of waking up with brighter, de-puffed eyes, and a great skin.”

4. Improved Blood Flow

Board-certified dermatologist Dr. Erum Ilyas elaborates, “The blood flow to the skin increases later in the day and the evening, and the healthy skin cells get an opportunity to repair and proliferate with their maximum activity during the night.”

While beauty sleep has a lot of benefits, you have to ensure that you sleep for at least a few hours to get the maximum benefits and stick to that number.

How Many Hours Of Sleep Do You Need?

Dr. Chimento recommends “7-9 hours of sleep as this gives enough to your skin and your body to rest and feel rejuvenated.”

At nighttime, you must prepare your body for rest. This helps you get a complete 7-9 hours of uninterrupted sleep. Here are a few tips you should follow.

How To Get Your Beauty Rest: Tips To Follow Before Bedtime

1. Create A Relaxing Environment

Before you unwind and settle into bed each night, it is vital to create a bedtime routine that helps you relax and eventually fall asleep. Keep all your gadgets away and make your bedroom a gadget-free zone. You may use darkening blinds or soothing lights and aromatherapy candles – whatever helps you feel relaxed. You may also indulge in relaxing activities like reading a book or journaling.

2. Avoid Stimulants Before Bed

To ensure you get good sleep every night, stay away from coffee, nicotine, and alcohol at least three to four hours before bedtime. They have a stimulating effect, which may take hours to wear off.

3. Check What You Eat

Never go to bed hungry or with a stuffed stomach. Not eating at all or eating a large meal before you go to bed can cause discomfort and hamper your sleep. Also, avoid spicy and acidic foods as they may cause stomach issues and heartburn.

4. Reduce Your Light Exposure

When it is dark, your brain secretes melatonin, a hormone that helps you sleep. Exposing yourself to light before bedtime can affect melatonin production. Avoid bright screens (like mobile, laptop, and television) at least 1-2 hours before sleeping. Avoid reading on backlit devices like tablets and ensure the room is dark.

5. Clean Your Sheets And Pillowcases Regularly

Your pillowcase is the closest anything can get to your facial skin while you sleep. It is, therefore, essential to wash your pillowcases regularly to remove any oil, dirt, and bacteria that may be accumulating on them and can cause skin infections like acne.

Since your skin heals at night, a proper nighttime skin care routine is crucial to fortify the skin’s healing process. Dr. Chimento says, “During the night, your skin is also more permeable and receptive to any products you apply before bed.” Here are a few tips to prepare your skin for beauty sleep.

How To Prepare Your Skin For Beauty Sleep

Wash your face properly to remove all dirt and grime. According to Dr. Chimento, “You should focus on detoxifying and cleansing your skin to clear all traces of dirt and grime from the day. Use exfoliating products that cleanse your skin without irritating it.”

Once your face is clean, you can apply protective and repairing ingredients to help your skin repair itself. Katie Noffsinger, a Michigan-based licensed esthetician and herbalist, says, “Skin care should align with the circadian rhythm (sleep/wake cycle), and there are two rules to do that – apply protecting ingredients in the morning and repairing ingredients at night.”

For repairing your skin at night, she suggests using the following ingredients:

  • Retinol: It enhances collagen and elastin formation, stimulates the blood vessels, and helps shed dead skin cells (6).
  • Amino Acids and Peptides: These ingredients help the body in repairing and rebuilding the skin (7),(8).
  • Tyrosinase Inhibitors: These ingredients (like arbutin and kojic acid) will target the overactive melanocytes (cells that produce melanin) and brighten your skin (9).
  • Alpha Hydroxy Acids: They exfoliate the skin and create pathways so that the skin can absorb products better (10).
  • Benzoyl Peroxide: It kills acne-causing bacteria and may help heal blemishes(11).

For your PM skin care routine, follow these steps:

  • Wash your face thoroughly with a gentle cleanser. If you have acne-prone or oily skin, use a cleanser with salicylic acid or benzoyl peroxide.
  • Use chemical exfoliators containing AHAs to exfoliate dead skin cells. However, exfoliate only once a week and avoid combining AHAs with BHA and retinol.
  • Apply a toner containing ceramides, peptides, amino acids, and other hydrating and soothing ingredients.
  • Use treatments or serums containing retinol or tyrosinase inhibitors.
  • Finish off with a nourishing moisturizer to lock all the goodness of the ingredients.

To Sum Up

Beauty sleep is all about giving your body and skin the required time to repair and heal. No matter how busy your schedule or routine looks, you must prioritize sleep and get at least seven hours of shut-eye every day. Your body perceives lack of sleep as a sign of stress, affecting the overall skin quality and texture and speeding up the aging process. If you have difficulty in sleeping or have insomnia, it is better to consult your doctor as chronic sleeplessness can trigger long-term health issues.

Expert’s Answers For Readers’ Questions
