Sulphate Free Sun Serum

What Is a Sulphate-Free Sun Serum?

A sulphate-free sun serum is a daily SPF formula made without sulphate surfactants, the kind of ingredient more commonly found in foaming cleansers than in serums or sunscreens. SIX:AM's Daily Call Sun Serum is formulated without sulphates, alongside 2% Niacinamide, Bisabolol, Adenosine, and SPF 50 PA++++ broad-spectrum protection.

Why "Sulphate-Free" Matters More for Cleansers Than Serums

Sulphates are surfactants, ingredients that create foam and lift away oil and makeup. That makes them common in face washes and shampoos, where a foaming or deep-cleansing effect is the point.

Serums and sunscreens are built differently. They're leave-on formulas designed to sit on the skin, not rinse-off products designed to foam and wash away. Because of this, sulphates aren't typically part of a serum-sunscreen formulation to begin with.

If you're specifically looking to avoid sulphates across your full routine, the more relevant place to check is your cleanser, not your sun serum.

What to Look for Instead in a Sun Serum

Since sulphates aren't the main formulation concern for a leave-on SPF product, the more useful checks are:

Non-comedogenic formulation. Whether the texture is likely to clog pores over hours of daily wear.

Fragrance and irritant load. Whether the formula includes added fragrance or ingredients more likely to trigger sensitivity.

UV filter quality. Whether the sunscreen offers genuine broad-spectrum protection rather than SPF alone.

The SIX:AM Formula

The Daily Call Sun Serum is formulated without sulphates, and combines 2% Niacinamide, Bisabolol, Adenosine, Sunflower Seed Oil, and SPF 50 PA++++ broad-spectrum protection with four UV filters (Ethylhexyl Triazone, BEMT, TDSA, and DHHB) for daily use.
