Nivea Cellular Luminous630 Anti Dark-Spot Post-Acne Marks Serum - UK Versus Eucerin Anti-Pigment Skin Perfecting Serum

Like hydroquinone, this ingredient helps with treating hyperpigmentation. In fact, studies show it works better than traditional hydroquinone.

Thiamidol is a potent tyrosinase inhibitor, meaning it blocks tyrosinase. Tyrosinase is the enzyme used by our bodies to create melanin.

A quick refresher: melanin gives our skin, hair, and eyes pigment or color. Skin exposed to UV will create melanin as a way to protect itself, AKA tanning.

Studies show thiamidol didn't induce the familiar side effects of hydroquinone: redness, itchiness, dryness, and worsening discoloration.

A study from Beiersdorf about the Eucerin Anti-Pigment Dual serum showed hyperpigmentation was reduced up to 75% after 12 weeks of continuous use.

For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regulations.

The term 'parfum' or '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 by INCI standards.

One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.

Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Parfum can also be used to mask or cover an unpleasant scent.
