What we leave out

No hydroquinone. No retinol. No harsh acids. And no fairness promises, not in our formulas, not in our words.

Correct, then protect.

The serum works on existing marks morning and night. The sunscreen stops new ones from forming. Each is built to layer with the other without pilling.

AM + PM

Correct

Two to three drops on clean, dry skin. Fast-absorbing, invisible under sunscreen or moisturiser.

In the world

Quiet, daily, unhurried.

Good to know

Everything worth knowing before you buy, from shade matching to what we test. Still curious? Message us on Instagram and we'll answer personally.

Is it suitable for sensitive or acne-prone skin?

Both formulas avoid the usual triggers: no drying alcohols, no heavy fragrance, no hydroquinone, no retinol, no harsh acids. The serum has completed a 24-hour Primary Irritation Patch Test on 24 volunteers to IS 4011:2018 and was found non-irritant. The sunscreen is still working through its own skin-compatibility testing, and we will publish that result the same way.

How long until I see a visible change?

Pigmentation on brown skin responds to daily protection plus time. Most people assess visible change over 4 to 8 weeks of consistent use, with the sunscreen preventing new marks while the serum works on existing ones.

"Melanin-rich skin has been misunderstood, under-tested and sold a fairness narrative for decades. uncaast exists to formulate for it properly, and to show the working. Every result we get back, you see too."
