Shea Butter (Butyrospermum Parkii)

Botanical name: Butyrospermum parkii

37.8%TEWL Reduction (24h)¹
58%Hydration Increase (24h)¹
1.5%Concentration Used

Mechanism of Action

Rich in oleic and stearic fatty acids plus vitamins A and E, Shea Butter reinforces the skin's lipid barrier, reduces transepidermal water loss (TEWL), and improves elasticity with consistent use.¹

Clinical Evidence

Key finding: In-vitro analytical testing recorded a 37.8% drop in transepidermal water loss and a 58% increase in skin hydration, both measured 24 hours after a single application.¹
Property Detail
Barrier Support Reduces water loss through the skin's outer layer.¹
Texture Fatty-acid profile improves elasticity and offsets dryness from mineral UV filters.¹

Formulation Rationale

High-concentration mineral filters like our 25% zinc oxide create a textural trade-off — excellent protection, but a risk of feeling dry or chalky without support. Shea Butter is specifically what allows this sunscreen to feel nourishing rather than heavy.

Usage Protocol

Included at 1.5% concentration in the Sunscreen; applied with your normal daily SPF routine.

Safety Profile

Well tolerated by most skin types. Those with known tree-nut allergies are sometimes advised to patch test first, though research suggests low cross-reactivity.

Where You'll Find It

Mineral Sunscreen SPF 50 (₹799)

Bottom line: The reason people who've avoided mineral sunscreens for their dry, chalky finish can comfortably wear this one daily.
