The percentage of alcohol used in skincare products is a highly debated topic, with various alcohols having different effects on the skin. Estheticians use alcohol-based products for a variety of reasons, from removing excess oil from the skin to disinfecting wounds. The type of alcohol and its concentration are crucial factors in determining its suitability for skincare. For instance, SD alcohol, denatured alcohol, ethanol, and isopropyl alcohol (commonly found in skincare products) can have a dehydrating effect on the skin. On the other hand, fatty alcohols derived from coconut or palm oil can be nourishing and beneficial for the skin. While some alcohols are safe for the skin in small concentrations, others can cause dryness, irritation, and skin barrier disruption. Therefore, it is essential to understand the specific alcohol type and its concentration before determining its suitability for esthetician use.

Skin types: Oily skin may benefit from alcohol-based products, while dry or sensitive skin may be irritated
Alcohol is a common ingredient in skincare products, from toners to moisturisers, and is used for various reasons. It helps dissolve other ingredients, provides a cooling sensation on the skin, and helps prevent bacteria growth. However, alcohol can also be drying and irritating to the skin.
There are several types of alcohols, and they have different effects on the skin. Fatty alcohols, such as cetyl, stearyl, and cetearyl alcohol, are used to improve the texture and feel of skincare products. They act as emollients and humectants, improving the skin's ability to maintain hydration. Fatty alcohols can also help to preserve a product's shelf life by preventing bacteria growth.
On the other hand, simple alcohols or volatile alcohols like isopropyl, methyl, or ethyl alcohol are generally best avoided in cosmetics. They are often used for their cooling and degreasing effects, especially for oily skin types. However, this can lead to dehydration, triggering excess sebum production.
For people with oily skin, alcohol-based products can help reduce oiliness and remove excess oil from the skin. "If you have very oily skin, you might want [a product] with a low-molecular-weight alcohol in it because you want to remove that oil," says Dr. Zampella. However, for those with sensitive skin, these products may cause dryness or irritation.
For dry or sensitive skin, it is recommended to avoid cosmetics with simple alcohol content. Simple alcohols can be very irritating and dehydrating, leading to contact dermatitis and other flare-ups. They can disrupt the skin's moisture barrier, leaving the skin vulnerable to other skin conditions.
The concentration of alcohol in a product is also important. If alcohol is one of the top ingredients, it is likely to dry out the skin. A reasonable place for alcohol to appear is lower on the ingredient list, as it indicates a low percentage and a lower risk of adverse reactions.
Overall, while alcohol-based products may benefit those with oily skin, they can irritate those with dry or sensitive skin. It is important to consider the type of alcohol and its concentration in a product, as well as individual skin characteristics, when deciding whether to use alcohol-based skincare products.

Alcohol content: Estheticians use products with varying alcohol percentages, depending on skin type and treatment
The alcohol content in skincare products is a matter of growing concern. Estheticians use products with varying alcohol percentages, depending on skin type and treatment.
Estheticians may use products with alcohol content ranging from 0-4% for dry, mature, or sensitive skin. This lower alcohol content is often found in skin-freshening lotions. For normal to combination skin, products with an alcohol content of 4-15% are suitable, as they help tone and tighten the skin. Oily and acne-prone skin types can tolerate higher alcohol concentrations of up to 35% to remove excess oil.
It is important to note that not all alcohols in skincare are harmful. Fatty alcohols, derived from coconut or palm oil, can be beneficial for the skin. They are used to thicken formulations and provide nourishment. Examples include cetyl, stearyl, and cetearyl alcohol, which act as emollients and moisturizers. Vitamins A1 (retinol) and E, beneficial for the skin, are also types of alcohols.
However, some alcohols should be avoided in skincare products. Simple alcohols like SD alcohol 40, denatured alcohol, ethanol, and isopropyl alcohol can have a dehydrating effect on the skin. They strip away the skin's natural oils and may damage the skin barrier, leading to enlarged pores and increased greasiness over time. Ethanol, in particular, can be drying for sensitive skin types.
When selecting skincare products, it is crucial to consider the concentration of alcohol and the overall formula. While small amounts of certain alcohols can be beneficial, excessive alcohol concentrations can lead to skin irritation, dryness, and disruption of the skin barrier.
Additionally, it is worth noting that rubbing alcohol, often containing 70% isopropyl alcohol, should be used with caution on the skin. While it can help clear pimples, it is not designed for long-term use due to its side effects and lack of scientific backing.

Fatty alcohols: Derived from coconut or palm oil, these alcohols are beneficial and nourishing for the skin
While some alcohols can be beneficial for the skin, others can be damaging. Estheticians use products with alcohol content ranging from 0-35%, depending on skin type. For instance, products for dry, mature, or sensitive skin have the lowest alcohol content (0-4%), whereas products for oily and acne-prone skin may contain up to 35% alcohol.
Fatty alcohols, derived from coconut or palm oil, are among the alcohols that are beneficial and nourishing for the skin. They are used to thicken formulations and provide a smoother, more stable texture to creams and lotions. Cetyl alcohol, for example, is a fatty alcohol produced by heating coconut oil and palm oil with a strong base. It functions as a light emollient, helping products to moisturize the skin without leaving a greasy residue.
Another example of a beneficial fatty alcohol is cetearyl alcohol, an emulsifier that enables liquids that do not naturally mix, such as oil and water, to remain combined without separating. This creates a more stable product with a smoother feel.
Fatty alcohols derived from coconut or palm oil also include stearyl alcohol, an emollient that helps trap moisture in the skin, and polyglyceryl-3 stearate, a natural emulsifier derived from glycerin and palm oil.
These fatty alcohols are distinct from simple alcohols like ethanol and isopropyl alcohol, which can have a dehydrating effect on the skin. While these simple alcohols may give a desirable cooling sensation, they can also strip away the skin's natural oils and damage the skin barrier, leading to enlarged pores and increased greasiness over time. Therefore, it is important to understand the different types of alcohols and their effects on the skin when selecting skincare products.

Evaporative solvent alcohols: These include SD alcohol 40, ethanol, and isopropyl alcohol, and have a dehydrating effect on the skin
Alcohol is a common ingredient in skincare products, and its use is determined by the specific skin type and needs of the individual. Estheticians and dermatologists often recommend skincare products with low alcohol content or advise against the use of certain types of alcohol for specific skin types.
Evaporative solvent alcohols, including SD alcohol 40, ethanol, and isopropyl alcohol, are known to have a dehydrating effect on the skin. These alcohols are often used in skincare products such as toners and gel moisturisers. They can give a tight, cooling, and refreshing sensation, especially for those with oily skin. However, they can also strip away the skin's natural oils and damage the skin barrier, leading to enlarged pores and increased greasiness over time.
SD Alcohol 40, also known as special denatured alcohol or ethanol, is commonly used in cold creams, hand lotions, hair lotions, and aftershaves. It helps heal wounds and skin ulcers while stimulating the growth of healthy tissue. Isopropyl alcohol, the main alcohol type in hand sanitisers, can be irritating to the skin, especially for those with dry or sensitive skin.
While these evaporative solvent alcohols can have a dehydrating effect, it's important to note that the concentration of alcohol in a product also plays a significant role in its impact on the skin. According to Dr. Hu, skincare products with an alcohol content greater than 1% can be irritating or dehydrating for those with already dry skin. However, when used as a solvent to aid absorption, alcohol is typically found at the bottom of the ingredient list and is not considered harmful.
Additionally, it's worth mentioning that not all alcohols are detrimental to the skin. Fatty alcohols, derived from coconut or palm oil, can be nourishing and beneficial. Examples include cetyl alcohol (a thickener), stearyl alcohol (an emollient), and cetearyl alcohol (an emulsifier). These alcohols help improve skin texture and complexion while keeping it moisturised.
In conclusion, while SD alcohol 40, ethanol, and isopropyl alcohol are known for their dehydrating effects, the overall impact of alcohol in skincare depends on various factors, including skin type, concentration, and the presence of other ingredients. It is always advisable to consult with a dermatologist or esthetician to determine the most suitable skincare routine for your specific needs.

Alcohol-free products: Some products labelled alcohol-free may still contain certain types of alcohol
When it comes to skincare, not all alcohols are created equal. Some alcohols, particularly fatty alcohols, can be beneficial to the skin. Fatty alcohols are derived from coconut or palm oil and are used to thicken formulations while also nourishing the skin. Examples include cetyl, stearyl, cetearyl alcohol, and propylene glycol. These alcohols are often found in products labelled as "alcohol-free", as the term "alcohol" in cosmetic labelling typically refers specifically to ethyl alcohol or ethanol.
On the other hand, some types of alcohol can be damaging to the skin, such as SD alcohol, denatured alcohol, ethanol, and isopropyl alcohol. These alcohols have a dehydrating effect and are often found in toners and gel moisturisers. They can strip away the skin's natural oils and damage the skin barrier, leading to enlarged pores and increased greasiness.
When selecting skincare products, it's important to read the ingredient listings carefully. While some alcohols can be beneficial, it's best to avoid products containing high concentrations of the more harmful types of alcohol, especially if you have oily or acne-prone skin. Additionally, be aware that products labelled as "alcohol-free" may still contain certain types of alcohol, so it's always a good idea to check the ingredients to make an informed choice.
Furthermore, the concept of "alcohol-free" extends beyond skincare. Many food and beverage products that are labelled as non-alcoholic may still contain small amounts of alcohol due to the fermentation process or other factors. For example, non-alcoholic beer typically contains about one-tenth the amount of alcohol found in regular beer, and certain sauces and meats can retain significant amounts of alcohol after cooking. Even some mouthwashes and cold medicines contain alcohol, which can be a concern for individuals recovering from alcoholism or alcohol use disorder. Therefore, it's important to read labels and be aware of the potential presence of alcohol in a variety of products, especially if avoiding alcohol is a health, faith, or lifestyle choice.
