Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!

Like other oils, Paraffinum Liquidum has emollient properties. Emollients help soothe and soften the skin. By creating a barrier to trap moisture within, emollients help keep your skin hydrated.

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 .
