Shea Butter

Shea Butter — a rich, semi-solid fat extracted from the nuts of the African shea tree, packed with fatty acids and vitamins that deeply moisturize and soften skin. It is a classic emollient used to relieve dryness and support the skin's protective barrier.

Key points

  • Shea butter is high in stearic and oleic acids along with vitamins A and E, giving it strong emollient properties.
  • It helps reduce transepidermal water loss, making it especially effective for dry, rough, or flaky skin.
  • It contains natural compounds with mild anti-inflammatory and soothing effects.
  • Its thick texture makes it well suited to body care, lips, and very dry areas.
  • Refined shea butter has a milder scent, while unrefined retains more of its natural nutrients and aroma.

Frequently asked

Can shea butter be used on the face?

Shea butter can be used on the face, though its richness may feel heavy or be comedogenic for some oily or acne-prone skin types. Using a thin layer or choosing lighter facial formulas can help.

Is shea butter safe for people with nut allergies?

Shea butter is derived from a tree nut but is generally low in the proteins that trigger allergic reactions, and reactions are considered rare. Those with nut allergies should still consult a doctor before use.
