Stress and acne are twin problems that have crossed the boundaries of millions of people across the globe. While most talk about the psychological effects of stress, its physical consequences, such as acne, are equally paralyzing. Can stress really cause acne? Let’s delve into this extremely complicated interaction between stress and hormones in the perspective of dermatology.

The Science of Stress and Acne

1. Cortisol and Stress Response

Stress activates the HPA axis (hypothalamic-pituitary-adrenal axis is your body’s main way of responding to stress), which in turn causes the adrenal gland to release the hormone cortisol(a vital hormone that impacts nearly all of your body’s tissues and organs), which initiates off physiological processes. This hormone, cortisol, plays a role in the body’s “fight or flight” response, preparing us to react to immediate danger. A high cortisol level leads to physiological reactions as follows: enhanced heart rate and blood pressure, the availability of increased glucose for energy, the inhibition of immunity, and hormonal production changes.

2. Hormonal Imbalance

Cortisol upsets the body’s main sensitive hormone balance, which involves:

• Insulin: Cortisol increases the level of insulin resistance, which leads to a fluctuating blood sugar level and inflammation. 
• Growth hormone: Cortisol inhibits production of growth hormones, which distracts regeneration of the skin and produces collagen. 
• Androgens (Testosterone, Dihydrotestosterone): Increased hormones lead to increased production of androgens which causes an increase in sebum production and pores become large, developing acne.

This hormonal change creates an ideal state for the development of acne.

3. Inflammation

The body reacts to stress in a variety of ways which promote inflammation within its systems.

• Cortisol can cause the development of pro-inflammatory cytokines(contribute to or aggravate inflammation).
• Stress acts on the immune cells that ultimately result in inflammation.

Increased inflammation leads to the following :

• Redness and irritation of skin
• Scarring of acne
• Post-inflammatory hyperpigmentation

Chronic inflammation creates a cycle of acne that is difficult to break-the clear skin.

4. Gut-Skin Connection

Stress modifies the bacteria in the gut, weakening the strength of the skin’s natural barrier and causing inflammation. The axis of gut-skin comprises:

• Altered gut microbiome
• Increased gut permeability; leaky gut
• Release of pro-inflammatory cytokines
• Dysregulation of skin barrier function
• Susceptibility to acne-producing bacteria (P. acnes)

The Gut-Skin Link. All these demonstrate the necessity of a well-balanced gut micro-environment for normal skin function.

How Does Stress Cause Acne?

1. Increase oil production

Cortisol stimulates the oil glands, resulting in:

• Excessive oily look
• Open pores
• Clogged pores
• Development of acne (blackheads, whiteheads, papules, and pustules)

This extra oiliness acts as an ideal bed for acne-causing bacteria (P. acnes).

2. Inflammation and Redness

Induced inflammation by stress results in:

• Redness, inflammation
• Swelling
• Post-inflammatory hyperpigmentation
• Acne lesions (papules, pustules, nodules)
• Infection and tendency to get acne scars

Since inflammation favors the mechanism of acne causation, it tends to become challenging to get clear skin.

3. Delayed Wound Healing

Stress negatively affects the healing process of the wound through:

• Collagen production is reduced
• Tissue repair is inhibited
• Inflammation is increased
• Acne lesions persist
• Healing is prolonged

Consequently, prolonged healing time makes the acne lesions chronic, and the skin problems are here to stay.

4. Damage to the Natural Barrier of the Skin

Stress removes a person’s natural barrier from his or her skin, which exposes it to:

• Bacteria (P. acnes)
• Pollution
• Irritants of no consequences
• Allergens
• Environmental stress

A burst skin barrier enables harmful substances, which causes inflammation and ultimately leads to the outbreak of acne .

Acne-Stress Cycle:

1. Stress Triggered Acne

Stress triggers the following:

• Hormonal imbalances (cortisol, insulin, androgens)
• Inflammation (increased cytokines, prostaglandins)
• Increased sebum production
• Damage to the skin barrier
• Dysregulation of the gut-skin axis

These physiological responses create a nidus for acne development.

2. Acne is also stress-promoting

Acne can precipitate:

• Emotional distress (anxiety, depression)
• Low self-esteem
• Social withdrawal
• Body image issues
• Anxiety about appearance

This emotional consequence is terrible in itself but also tends to heighten baseline stress.

3. Vicious cycle

Stress-acne fuels each other in the most direct, vicious way.

Stress → Acne → Emotional Distress → Increased Stress → Worsening Acne

Hormonal imbalances → Inflammation → Skin barrier disruption → Increased stress

To break this cycle one would have to address issues concerning stress management as well as to treat the acne.

Consequences of the Stress-Acne Cycle

• Chronic acne
• Acne scarring
• Emotional distress
• Mental health issues (anxiety, depression)
• Poor quality of life
• Social isolation

Breaking the Cycle

• Manage stress through yoga, meditation, and deep breathing.
• Follow a detailed skincare routine (gentle cleansing, hydration, protect your skin from the sun)
• Seek out someone who can guide you (dermatologists, therapists)
• Regulate your hormones (see your doctor)
• Build body self-esteem

Key Facts

• Nearly 50 percent of people with acne said they had a flare-up due to stress, according to the American Academy of Dermatology
• 75 percent of adults who had acne felt it made them feel stressed, according to research in the British Journal of Dermatology
• Researchers determined in the Journal of Clinical and Aesthetic Dermatology that acne increases stress by 34 percent

Stress Relieving Techniques

    Practice every day:

• Yoga: Decreases cortisol levels, mood improved 
• Meditation: Reduction in stress, relaxes
• Deep Breathing: Reduces blood pressure, calms the mind
• Exercise: Releases endorphin, mood improved
• Mindfulness: Enhancement of awareness, anxiety reduced
• Journaling: Express the self and clears thoughts
• Progressive Muscle Relaxation: Relaxation of muscles, reduces tension

Skincare Routine

Design an everyday gentle routine.

• Cleansing: Use non-comedogenic
• Moisturizing: Oily and non-comedogenic products for hydrating skin
• Sun protection: Use a broad-spectrum SPF 30+ sunscreen.
• Exfoliate Gently 1-2 times a week
• Spot treatment: Apply products specific to acne on areas that have broken out

Dietary Modulation

Have as much as:

• Balanced nutrition: Whole foods, fruits, veggies, whole grains
• Omega-3 rich foods: Fatty fish, flaxseeds, walnuts
• Probiotics: Yogurt, kefir, fermented foods
• Hydrate: Drink lots of water
• Avoid: Processed food and sugar

Professional Help

Consult:

• Dermatologists: Skincare consulting for individual skin
• Therapists: Stress management and emotional support
• Nutritionists: Dietary plans for individual needs
• Wellness coaches: Wholesome lifestyle consulting

Conclusion
