Many people consider using alcohol to cleanse their face, believing it effectively removes oil and impurities. However, its interaction with facial skin is complex, and the answer to whether it is beneficial for cleansing is not straightforward.
Types of Alcohol and Skin Interaction
Not all substances labeled “alcohol” in skincare products behave the same way on the skin. There are two main categories: volatile alcohols and fatty alcohols. Volatile alcohols, such as ethanol (also known as ethyl alcohol, SD alcohol, or denatured alcohol) and isopropyl alcohol (rubbing alcohol), are characterized by their quick-drying nature. These types of alcohols act as solvents, helping to dissolve other ingredients and create a lightweight feel in formulations. When applied to the skin, they rapidly evaporate, which can give a temporary sensation of tightness or cleanliness. However, this rapid evaporation also means they can readily strip the skin’s surface of its natural oils, known as lipids.
In contrast, fatty alcohols, including cetyl, stearyl, and cetearyl alcohol, are not drying or irritating. Instead, they function as emollients, helping to soften and smooth the skin. Fatty alcohols also act as emulsifiers, assisting in blending oil and water-based ingredients within products, and can form a protective barrier on the skin to prevent moisture loss.
Detrimental Effects on Facial Skin
The regular use of volatile alcohols on facial skin can lead to several negative effects. These alcohols disrupt the skin’s delicate barrier, which is its outermost protective layer. They achieve this by dissolving the natural lipids that are essential for maintaining the barrier’s integrity. This disruption increases transepidermal water loss (TEWL), meaning more water evaporates from the skin, leading to dryness and dehydration.
A compromised skin barrier can result in irritation, redness, and heightened sensitivity, making the skin more vulnerable to external irritants. Paradoxically, stripping the skin of its natural oils can trigger the sebaceous glands to produce even more oil in an attempt to compensate for the dryness. This compensatory oil production can worsen conditions like acne, rather than improving them.
Volatile alcohols can also negatively impact the skin’s microbiome, the community of beneficial microorganisms living on the skin’s surface. An imbalance in this microbiome can contribute to inflammation and exacerbate skin issues. Furthermore, alcohol’s inflammatory effects can lead to increased redness and can worsen existing conditions such as rosacea or psoriasis.
Common Beliefs and Realities
Many common beliefs about using alcohol on the face do not align with scientific understanding. One misconception is that alcohol effectively “disinfects” the skin. While alcohol possesses antimicrobial properties, its application to the skin is far too harsh for regular use. The benefit of disinfection is outweighed by the damage it inflicts on the skin’s protective barrier and beneficial microbiome.
Another common belief is that alcohol can “dry out pimples” and clear acne. Although it may initially appear to dry a blemish, this process is counterproductive. Drying out pimples with alcohol can damage the surrounding skin, leading to further irritation, inflammation, and potentially worsening the breakout or causing post-inflammatory hyperpigmentation.
Some individuals believe alcohol can “tighten” pores. Any pore-tightening effect observed is temporary and superficial. Pores do not actually open and close; rather, they can appear larger due to clogging or loss of skin elasticity. While alcohol may temporarily constrict skin, this effect is fleeting and does not address the underlying causes of visible pores.
Recommended Skincare Practices
Instead of harsh alcohols, a gentle approach supports skin health. Begin with a mild, pH-balanced, sulfate-free cleanser. Look for ingredients like glycerin, niacinamide, and panthenol, which help to cleanse without stripping the skin and support the moisture barrier. Cleansing should remove impurities without leaving the skin feeling tight or dry.
Following cleansing, proper moisturizing is essential to maintain skin hydration and barrier function. Products containing ceramides are beneficial as these lipids help restore and strengthen the skin’s protective barrier, preventing moisture loss. Hyaluronic acid, a powerful humectant, attracts and holds moisture in the skin, contributing to plump and hydrated skin. These ingredients work synergistically to enhance hydration and barrier repair.
For specific concerns like acne, use targeted treatments with proven ingredients. Salicylic acid helps to unclog pores and reduce redness, while benzoyl peroxide kills acne-causing bacteria and reduces excess oil. Retinoids, available over-the-counter or by prescription, promote cell turnover and prevent clogged pores. If acne is persistent or severe, consulting a dermatologist can provide personalized guidance. Simplifying the skincare routine and avoiding known irritants can also help repair a damaged skin barrier.
