What ingredients are deliberately left out of this formula (parabens, dyes, mineral oils, petroleum jelly), and why might that matter for daily use?

Parabens are preservatives that some prefer to avoid due to potential skin sensitisation, especially on already compromised barrier skin. Synthetic dyes serve no functional purpose in a hand cream and can trigger contact reactions in fragrance-sensitive individuals. Mineral oils and petroleum jelly are highly effective occlusives, but they create a heavy, sometimes tacky film that many find unpleasant during daytime activities; they can also interfere with the skin's natural lipid production if used exclusively long-term.

By omitting these four categories, the formula relies on shea butter's intrinsic stability and emollience to deliver barrier support with a quicker, drier after-feel. This makes reapplication after every hand wash — potentially 8–12 times a day — more realistic, because you're not waiting for a greasy layer to absorb. For people who wear gloves for work, the lighter residue also reduces maceration risk inside the glove cuff.
