Retinol, AKA Vitamin A. Unlike AHA's, retinol does not remove the top layer of old and dead skin cells. Instead, it travels directly to the middle layer and gets to work. It neutralizes free radicals, boosting elastin and collagen production. This in turn makes retinol effective in removing fine lines, wrinkles, and enlarged pores.

Retinol is sensitive to breakdown when exposed to sun and air. It will also make your skin more sensitive to the sun, so it is recommended to wear SPF after applying retinol.

It is not recommended to use any retinols while pregnant. Retinol may cause irritation in some people.

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "Parfum" in the ingredients list is a different mixture.

In the US, the alternative name for parfum is 'fragrance'. 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. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

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

Products use parfum often to give products a scent or cover up smells of different ingredients.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
