How the skin works at night
During the day, your skin is in protection mode. It is hard at work defending itself against free radical attacks and damage caused by stressors including UV light, pollution, temperature, and other lifestyle factors.
At night, skin switches into repair mode. This is the time for skin to recover and deeply rejuvenate itself on a cellular level. Skin is also more permeable at night. While this means moisture evaporates from the skin quicker than day time, the good news is that skin is more receptive to the care of topical treatments.
Your morning and evening skincare routine play an essential role in maximizing the natural restoration process and protecting skin hydration levels.
The role of Melatonin and Human Growth Hormone
Melatonin and human growth hormone (HGH) are your skin’s greatest natural alleys during sleep.
Melatonin is a hormone secreted by the brain’s Pineal gland and is responsible for controlling the body’s sleep/wake cycle. It also assists in cellular repair and the production of antioxidant enzymes work to reverse and repair cells.
(HGH) is a hormone that initiates cellular regeneration providing the collagen and elastin necessary to support thicker, firmer skin.
Both melatonin and HGH levels rise while we sleep and the elevation of these hormones is crucial for optimal skin repair.

Factors impacting sleep quality
To encourage your skin to recover optimally, the quality of your sleep matters. When you’re unable to wind down and sleep patterns are light or disrupted, the levels of melatonin and HGH released become unstable and start to decline. This, in turn, impacts your skin’s entire regeneration process.
A few of the common culprits responsible for poor night’s sleep include stress-
During times of stress, the amount of cortisol - a stimulating, alerting hormone - rises in our bodies. You may know cortisol as ‘the stress hormone’ but it also plays an important role in regulating the sleep cycle.
Healthy levels of cortisol rise gradually in the second half of the night’s sleep, helping ease the body into a wakeful state.
Issues arise when prolonged or high levels of stress mean the body remains in ‘alert’ mode and the natural sleep cycle is disrupted.
Research also tells us that prolonged stress can trigger or aggravate inflammatory skin conditions including psoriasis, atopic dermatitis, acne, and contact dermatitis.
Disrupted circadian rhythms
Circadian rhythm refers to your body’s own internal clock. One of its key roles is the regulation of your natural sleep/wake cycle.
When our natural circadian rhythm becomes disrupted it can have a detrimental effect on the skin. Transepidermal water loss, skin blood flow, and skin temperature are all influenced by our personal circadian rhythm.
For quality sleep, you need to address issues that throw your natural circadian rhythm off course. For example, too much screen time (blue light stimulation) right before bed.
Sleep, Skin, and Your Immune System
Your immune system and sleeping patterns are intrinsically linked. Not getting enough sleep weakens your immune defenses which in turn makes skin more vulnerable to inflammation, hypersensitivity, and other concerns.
When your immune system is compromised skin doesn’t heal as quickly, acne can be triggered, and you may be more sensitive to things (fragrance, pollens, etc) you wouldn’t usually have a reaction to.
Rhythmic Skin Routines
Your morning skincare routine should help your skin protect itself against daytime stressors to prevent or minimize free radical damage.
Antioxidants are the first line of defense against free radical attacks so including antioxidant-rich products in your morning routine is a must. Reinforcing hydration is also key for your morning routine.
Vitamin C - Brightening with high antioxidant activity to neutralize free radical damage.
Vitamin B5 (panthenol) - Anti-inflammatory, hydrating, and healing.
Antioxidants - Antioxidants can help protect against the damage caused by external factors faced by your skin during the day.
SPF ingredients - Whether you choose a physical or chemical sunscreen, SPF protection is a must during the day.
Skin permeability is also higher in the evening than during the day which means it’s more receptive to products at night.
Retinol and retinoids - (Vitamin A ) Promotes cell renewal, brightens skin tone, addresses signs of aging, clinically shown to increase skin's natural Hyaluronic acid production.
Peptides - Skin repairing, increase moisture levels, and elasticity.
Hyaluronic acid - Restores skin hydration levels at night.
Vitamin B3 (niacinamide) -Strengthens the skin’s surface and protects against moisture loss.
Alpha and Beta Hydroxy Acids - Exfoliation and skin brightening.
