Dermalogica Daily Microfoliant Exfoliator Versus Kate Somerville ExfoliKate® Intensive Pore Exfoliating Treatment

Limonene acts as an antioxidant, meaning it helps neutralize free radicals.

When exposed to air, oxidized limonene may sensitize the skin. Because of this, limonene is often avoided by people with sensitive skin.

The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term. For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance.

Unlike other exfoliants, papain can work without causing significant irritation.

Beyond exfoliation, its proteolytic action also helps soothe irritated skin and supports the healing of minor wounds.

A 2024 in vivo/in vitro study confirmed its potential to suppress skin inflammation and improve transepidermal water loss (TEWL) in atopic dermatitis models.

Just one thing worth noting: there are reports of allergic responses in individuals with a papaya or latex sensitivity. Be sure to patch test if you're in this camp.

Salicylic acid is also known for its soothing properties. It has a similar structure to aspirin and can calm inflamed or irritated skin, making it a good option for acne-prone skin that is also sensitive.

Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product.

It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing this ingredient into your routine.

While salicylic acid does not increase sun sensitivity, it’s still important to wear sunscreen daily to protect your skin.
