Acne-prone skin requires careful attention when choosing skincare products. While many ingredients promise clear and glowing skin, some can worsen acne or clog pores. If you are prone to breakouts, it is essential to understand which ingredients to avoid in order to keep your skin balanced and healthy. The following five ingredients, though common in many skincare products, could be contributing to your skin concerns. By avoiding these ingredients, you can prevent irritation, clogged pores and more frequent breakouts. Read on to discover which ingredients to steer clear of and why they may be hindering your skincare routine.
Sodium Lauryl Sulfate (SLS)
Sodium Lauryl Sulfate is a common cleansing agent found in many shampoos, body washes and facial cleansers. While it effectively removes dirt and oils, it can strip the skin of its natural moisture. For acne-prone skin, this can lead to an increase in oil production as the skin compensates for its dryness, potentially clogging pores and causing breakouts. Additionally, SLS can irritate the skin, causing inflammation, redness and further acne flare-ups. Opt for sulfate-free cleansers that are gentler and more hydrating.

Fragrance (Synthetic or Natural)
Fragrance is a common ingredient in skincare products, but it can irritate sensitive or acne-prone skin. Synthetic fragrances, in particular, contain chemicals that can trigger allergic reactions or inflammation. Even “natural” fragrances, such as essential oils, can be irritating for some individuals. Inflammation from fragrances can aggravate acne and increase the likelihood of breakouts. When choosing skincare, always check the label for fragrance-free options, or select products with minimal ingredients.

Isopropyl Myristate
Isopropyl Myristate is often used in cosmetics and skincare products to help other ingredients penetrate the skin more easily. However, it is comedogenic, meaning it can clog pores and trigger acne. This ingredient is particularly problematic for oily or acne-prone skin, as it can trap excess oil and bacteria inside the pores, leading to breakouts. It is best to avoid products containing this ingredient, especially if you are prone to blackheads or cystic acne.

Alcohol (Denatured Alcohol and Isopropyl Alcohol)
Alcohol-based products are often used for their quick-drying properties and ability to remove excess oil from the skin. However, denatured alcohol and isopropyl alcohol can be extremely harsh on acne-prone skin. These alcohols can strip the skin of its natural moisture, leading to dryness, irritation and an overproduction of oil, all of which can worsen acne. Instead, look for alcohol-free toners or moisturisers that hydrate and balance the skin without causing irritation.

Mineral Oil
Mineral oil is a petroleum-based ingredient commonly found in SPF, moisturisers and makeup removers. While it creates a barrier to lock in moisture, it can also clog pores and prevent the skin from breathing, making it problematic for those with acne-prone skin. Mineral oil can create a greasy layer on the skin, trapping sweat, oil and bacteria that could lead to breakouts. Choose non-comedogenic moisturisers and products labelled as “oil-free” to avoid this ingredient.
