A dermatology study published in 2020 found that more than a third of over 900 study participants had at least one allergic reaction to cosmetic ingredients. From a tingle to an all-out rash or constant red – some ingredients in our regular skin products could be the sneaky culprit. Although skincare products help restore and maintain our skin health, it is wrong to think that every chemical is compatible with every face. Understanding which chemicals are more prone to cause an allergic reaction helps you make informed choices and save yourself from these unwanted reactions.
Here, we explain 11 skincare ingredients that are notorious for causing various kinds of allergic reactions. Remember that everyone’s skin reacts differently, so what triggers a response for one can be harmless for another. Still, it is good to stay cautious, especially if you have sensitive skin or a history of allergies.
1. Fragrance (Parfum)
Fragrance is among the most prevalent allergens in skincare products. Either synthetic or natural, fragrances can irritate, cause rashes, and even respiratory distress in sensitive skin. The issue with “fragrance” is that it tends to cover a mixture of many chemicals, so it’s hard to identify the specific irritant.
Fragrance-free or unscented products are usually the better choice, especially for those with reactive skin. Face Facts Wonder Cream Fragrance-Free is an excellent choice for a fragrance-free product.

2. Preservatives (Parabens and Formaldehyde-releasers)
Preservatives extend skincare products’ shelf life by preventing bacterial growth. Some preservatives, however, such as parabens and formaldehyde-releasing agents (DMDM hydantoin or imidazolidinyl urea), have been reported to cause allergic contact dermatitis. Those with eczema or very sensitive skin must use caution when using products containing these ingredients. The Belhuman Niacinamide Brightening Cream and Exfoliating Treatment Shower Gel set is a preservative-free, clean skincare product for sensitive skin.

3. Essential Oils
Although essential oils are of natural origin, they can irritate sensitive skin types. Oils like lavender, peppermint, tea tree, and citrus oils are common in natural skincare products but can also induce reactions such as redness, itching, or inflammation. They are especially powerful when applied at high concentrations or over damaged or compromised skin. Body butters like shea butter and cocoa butter can be an alternative to essential oils.

4. Lanolin
Lanolin is a humectant derived from sheep wool found in creams and ointments commonly recommended for dry skin. It is a good moisturiser but can cause allergic reactions, particularly in people who are allergic to wool. It is known to make skin red, swollen, and itchy. Classified as teen-free, the Ordinary Alpha Arbutin 2% + Ha is free of Lanolin.

5. Sodium Lauryl Sulfate (SLS)
SLS is a surfactant in most shampoos, face washes, and cleansers, mainly used to create foam. Although it is perfect for removing dirt and oil from the skin, it can also remove the natural oils, leading to dryness and irritation. SLS can cause redness, burning, and allergies in sensitive or dry skin. Gently use alternatives such as sodium laureth sulfate or non-sulfate cleansers. The Simple Moisturising Facial Wash is an excellent option as it is an SLS-free face wash.

6. Alcohol (Denatured Alcohol or SD Alcohol)
While not all alcohols are bad for the skin, SD alcohol and denatured alcohol are particularly drying and harsh. They are typically added to toners and acne products for a matte finish or a quick-drying sensation. These types of alcohol, however, can dissolve the skin’s protective barrier and lead to irritation, mainly when used over a long period. If you are looking for an alcohol-free product, try the Neutrogena Alcohol-Free Toner.
