"Tried everything from the high street to the posh counters: cakey by lunchtime and sitting in my lines. Wore this to my daughter's wedding, cried half the day and it didn't budge."

The Seyun philosophy
Your skin has changed. Your foundation should too.
After 35, skin grows drier, tone shifts and the shade you've relied on for years quietly stops matching. Seyun is one adaptive formula, drawn from Korean skin science, that reads your complexion and settles into it.
Meet the formula
How it adapts
White in the bottle. You on your skin.
-
I
Dot on one pump
Over forehead, cheeks and chin. One pump is enough for the whole face.
-
II
Blend, and watch
Micro-encapsulated pigments release as you blend, settling to your own warmth and undertone in seconds.
-
III
Wear it all day
A weightless, breathable finish that stays true for 16+ hours, without creasing or turning orange.
No shade to choose
One formula. Every tone.
No more guessing online, no more too orange or too pale. The same bottle adapts to fair, medium, tan and deep skin alike.

In their own words.
From women who had all but given up on foundation, until they stopped shade-matching.

"I've spent hundreds of pounds on expensive brands that promised a lot and didn't deliver. Trust me, this is the one. It even matches when I have a tan. Ordering my third bottle."

"Going through the menopause I'd struggled to find anything that doesn't dry out during the day. This one doesn't cling to my dry patches at all. Best I've found."

"I have mature skin with dark circles and age spots. I can't believe how well this covers and lasts. I don't need anything on top, and nothing looks thick or cakey."

"I was sceptical with it being white in the bottle. Pale skin makes it so hard to find a match. I always end up orange or ghostly. This actually matched, even in daylight."

Shop nowHow can one shade match my skin?
The cream is white in the bottle and holds pigment in tiny colour capsules. As you blend, they release and settle into your natural tone, from fair to deep.
Will it settle into fine lines?
No. The lightweight, hydrating formula moves with your face and blurs lines instead of sinking into them.
How long does one bottle last?
One pump covers the whole face, so a bottle lasts most women around a month of daily wear.
What if it isn't right for me?
You're covered by our 30-day shade promise. If it isn't your perfect match, tell us within 30 days and we'll refund you in full.
