Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

Masking, Perfuming

Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.

Also called "fragrance", this ingredient 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.

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.

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.

This stuff is extremely stripping. You pretty much will have matted hair if you dare to double cleanse with it; you'll have to use a conditioner with heavy butters, oils and or silicone to detangle if you use this.

You'll have to scrub and use quite a lot since leaving it on even for more than 15 minutes isn't enough. So, use a scalp massager of some sort but that doesn't guarantee a clean Show more

I used this to correct the skin color of my sunburnt shoulders and back. It felt drying when using it but this product combined with physical exfoliation using a brush loofah removed my tan lines and reverted my skin color to how it was from childhood. Some of my scar marks from a long time ago also disappeared after using this.

A very hydrating moisturizer and sunscreen are required after Show more

Effective dark spots corrector soap but remember it can be drying and causes sun sensitivity, so always use moisturizer(night) and sunscreen(morning) after using this soap because if not you will get the opposite result that you want from this product .
