Smoking and its Effect on Skin | Comprehensive Review
Smoking is one of the main harmful factors for human health, which has devastating effects on the internal and external organs of the body, including the skin. The skin, as the largest body organ, is directly affected by toxins and chemicals in cigarette smoke and undergoes structural and functional changes in the long term.
The effect of smoking on skin quality
Smoking is one of the main factors that reduce skin quality and accelerate the aging process. Chemicals in cigarettes, including nicotine and other toxins, directly affect the health and beauty of the skin. Here are some of the most important effects of smoking on the skin:
1. Accelerates the aging process of the skin
Smoking reduces the production of collagen and elastin; these two proteins are responsible for the strength and flexibility of the skin. Their reduction leads to the appearance of premature wrinkles and sagging skin.
2. Reduced oxygen supply to the skin
Nicotine causes blood vessels to constrict and restrict blood flow to the skin. As a result, the skin cannot receive enough oxygen and nutrients, which causes the skin to become dry, dull, and dull.

3. Paleness and skin discoloration
Smokers often experience pale or dark skin. This discoloration is caused by impaired blood circulation and the accumulation of toxins in the skin tissues.
4. Increased risk of skin diseases
Smoking can weaken the body’s immune system and make the skin susceptible to diseases such as psoriasis, eczema, and acne.
5. Deep wrinkles around the lips and eyes
Repeated facial movements when smoking, such as pursing the lips to puff and keeping the eyes half-closed to block out the smoke, lead to localized and deep wrinkles in these areas.
6. Impaired wound healing
Smoking reduces the function of the immune system and impairs blood flow, which reduce the skin’s ability to heal wounds.
7. Reduced skin radiance and vitality
Smoking damages the skin’s protective layer and removes its natural moisture. This will lead to a loss of skin radiance and vitality.
8. Increased risk of skin cancer
Some studies have shown that the chemicals in cigarettes can increase the risk of skin cancer.
To prevent the negative effects of smoking on the skin, quitting smoking is the most important step. Using care products containing antioxidants, drinking enough water, having a healthy diet, and visiting a dermatologist can help improve the condition of the skin.
Smoking and specific skin problems
Smoking not only reduces the overall quality of your skin, but it can also lead to or worsen specific skin problems. Chemicals in cigarette smoke, such as nicotine, carbon monoxide, and other toxins, directly affect skin cells and the immune system. Here are some specific skin problems associated with smoking:
1. Psoriasis
Smoking can increase your risk of developing or worsening psoriasis. This autoimmune skin condition is characterized by red, scaly patches. The nicotine in cigarettes can impair your immune system and increase inflammation.
2. Acne
Smoking can worsen acne by reducing blood circulation and disrupting the skin’s natural oil production. Smoking also clogs pores and traps toxins in the skin’s underlying layers.
3. Deep Wrinkles
Repetitive movements such as puffing and direct skin contact with toxins in cigarette smoke can lead to deep wrinkles around the lips and eyes. This effect is known as “smoker’s wrinkles.”
4. Chronic Wounds
Smoking impairs blood flow and oxygen delivery to skin tissues. This reduces the skin’s ability to heal wounds, especially surgical or burn wounds, and increases the risk of infection.
5. Skin Cancer
Smoking is a risk factor for certain types of skin cancer, especially squamous cell carcinoma. Toxic chemicals in cigarettes can damage the DNA of skin cells.
6. Dermatitis
Smoking can increase skin sensitivity and inflammation, causing contact dermatitis or eczema. This occurs because the immune system is weakened and the skin’s protective barrier is disrupted.
7. Vitiligo
Some studies have shown that smoking can increase the risk of vitiligo, an autoimmune disease that causes white patches on the skin. Nicotine may damage pigment-producing cells (melanocytes).
8. Stretch Marks
By reducing collagen and elastin production, smoking can make the skin more prone to stretch marks or striae. This condition occurs because the skin’s elasticity is reduced.
Prevention strategies
Quit smoking: The first step to preventing certain skin problems is to stop smoking.
Keep your skin moisturized: Use moisturizers to reduce dryness and skin sensitivity.
Visit a specialist: If you have skin problems, consult a dermatologist.
A healthy diet: Consuming foods with antioxidants, and vitamins C and E can help reduce skin damage.
Smoking not only hurts the overall health of the body but also causes numerous skin problems that have a significant impact on the appearance and self-confidence of the person.
The effect of smoking on wound healing
Smoking has a destructive effect on the wound-healing process and can greatly slow down or even disrupt the healing process. The chemicals in cigarettes, such as nicotine, carbon monoxide, and other toxins, affect the functioning of the circulatory system and tissue regeneration. The following is a review of the effects of smoking on various aspects of wound healing:
1. Reduced blood flow and oxygen supply
Nicotine causes blood vessels to narrow (vasoconstrict), which reduces blood flow to damaged tissues.
Carbon monoxide in cigarette smoke impairs cell regeneration by reducing oxygen supply and reducing the wound healing process.
2. Reduced collagen production
Collagen is a key component in the wound-healing process. By inhibiting collagen synthesis and reducing its quality, smoking causes poor formation of new tissue and reduces wound strength.
3. Impaired immune function
Smoking weakens the body’s immune system. This reduces the body’s ability to fight infections and increases the likelihood of wound infections.
4. Chronic inflammation
Chemicals in cigarettes can cause chronic inflammation, which makes the wound-healing process longer and more complicated.
5. Increased risk of tissue necrosis
Reduced blood flow due to smoking can cause tissue death (necrosis), especially in surgical wounds or areas that need more oxygen. For this reason, it is strongly recommended to avoid smoking and tobacco use for at least a week before and after hair transplantation in Shiraz and eyebrow transplantation in Shiraz and other cosmetic procedures.
Recommendations for improving wound healing in smokers
Quit smoking: Even temporarily quitting smoking before surgery or during the recovery period can have a positive effect on wound healing.
Consume vitamin C and protein: These substances help produce collagen and accelerate the healing process.
Wound care: Use antiseptic products and visit your doctor regularly to monitor the condition of the wound.
Keeping the body hydrated: Drinking enough water is essential to maintain moisture and nourish the skin.
Smoking is a detrimental factor in wound healing, not only slowing down the healing process but also increasing the risk of infection and side effects. Quitting smoking, or at least reducing it during recovery, can help you heal faster and more effectively.
How does smoking lead to premature aging?
Smoking is known to be one of the main causes of premature aging. The chemicals in cigarette smoke, including nicotine and other toxins, severely affect the health of the skin and its natural regeneration processes. Here are the main reasons for this phenomenon:
1. Reduced blood flow and oxygen supply to the skin
Nicotine causes blood vessels to narrow, reducing blood flow to the outer layers of the skin.
Reduced blood supply leads to reduced oxygen and nutrients, which makes the skin dull, lifeless and prone to damage.
2. Accelerated collagen and elastin breakdown
Smoking disrupts the production of collagen and elastin (proteins essential for skin strength and elasticity).
The chemicals in cigarette smoke cause these proteins to break down, resulting in sagging skin and the appearance of wrinkles.
3. Increased production of free radicals
Cigarette smoke contains free radicals that damage skin cells.
These molecules damage DNA and accelerate the aging process.
4. Deep lines and wrinkles
Smoking causes dynamic lines, especially around the mouth and eyes (such as smile lines and crow’s feet lines).
Over time, these lines deepen and the skin looks older.
5. Reduced moisture and dryness
Smoking reduces the skin’s natural moisture level, making it dry and cracked.
Dry skin makes the skin prone to wrinkles and premature aging.
6. Pale and dull skin
Cigarette smoke changes the color of the skin over time, making it yellow, gray, or dull.
Reducing oxygen to the skin takes away its natural glow.
7. Increased UV damage
Smoking can increase the skin’s sensitivity to ultraviolet (UV) rays, which increases the risk of photodamage and dark spots.
8. Reduced skin repair ability
The toxins in cigarettes reduce the skin’s ability to repair and heal itself.
This makes it slower for the skin to heal and the signs of aging to appear more quickly.
Smoking greatly accelerates the skin’s aging process by destroying collagen, reducing oxygen delivery, and increasing free radicals. Quitting smoking and following a diet rich in antioxidants can help repair skin and prevent premature aging.
Methods to prevent and treat the effects of smoking on the skin
Smoking is one of the main causes of skin damage, but with lifestyle changes and appropriate treatments, its effects can be reduced or prevented. The following are effective methods to prevent and treat this damage:
1. Quitting smoking: the most important step
Quitting smoking is the first and most important step to prevent further damage to the skin.
After quitting smoking, blood flow and oxygen supply to the skin improves, and the skin gets a better chance to regenerate.
2. Consume foods rich in antioxidants
Antioxidants help reduce the damage caused by smoking by neutralizing free radicals.
Foods containing vitamin C, vitamin E, beta-carotene, and zinc help repair and brighten the skin.
Examples: fresh fruits (oranges, berries), vegetables (spinach, broccoli), and nuts.
3. Moisturize regularly
Using moisturizers containing hyaluronic acid and ceramides helps to retain skin moisture.
Dry skin caused by smoking is reduced with this method and the appearance of the skin improves.
4. Protect from sunlight
Smoking increases the skin’s sensitivity to UV rays and exacerbates premature aging.
Using sunscreen with SPF 30 or higher is essential daily.
5. Use products containing retinoids or retinol
Products containing retinoids help increase collagen production and reduce lines and wrinkles.
These products are best used under the supervision of a dermatologist.
6. Exfoliate regularly
Exfoliating removes dead skin cells and helps to brighten the skin.
Use alpha-hydroxy acids (AHA) or beta-hydroxy acids (BHA) for gentle exfoliation.
7. Stay hydrated
Drinking enough water helps to keep your skin hydrated and detoxified.
At least 8 glasses of water a day are recommended.
8. Consult a dermatologist
A dermatologist can recommend professional treatments like microneedling, laser treatments, and chemical peels to repair damaged skin.
9. Use natural face masks
Masks containing natural ingredients like honey, avocado, and aloe vera help soothe and repair the skin.
These nutrients nourish the skin and help with cell regeneration.
10. Exercise regularly
Exercise increases blood flow, helping the skin receive more oxygen and nutrients.
Sweating from exercise flushes toxins from the skin.
11. Get enough sleep
Getting enough sleep helps your skin repair and look younger.
At least 7 to 8 hours of sleep per night is recommended.
Although smoking has profound negative effects on the skin, adopting a healthy lifestyle, proper care, and using professional treatments can reduce these effects and help maintain skin health. For faster recovery, quitting smoking and consulting a dermatologist is of utmost importance.
Conclusion
Smoking not only negatively affects the overall health of the body, but also the beauty and vitality of the skin. This harmful habit exposes the skin to premature aging and serious damage by reducing collagen production, weakening blood flow, and increasing free radicals. However, quitting smoking and adopting a healthy lifestyle can help improve the condition of the skin and accelerate its regeneration process. Proper skin care, a healthy diet, and consulting a dermatologist are among the most important steps to restore health and radiance to your skin. Remember, it is never too late to choose a healthier path and take better care of yourself.
