For: Dry & Sensitive-Feeling Skin
A pharmacist-selected formula: a short ingredient list built around asiaticoside and blue tansy oil.
When skin is dry and reacts easily, long ingredient lists become a guessing game. Every extra extract is one more thing that might not agree with you.
ILLON Signal Booster Blue · 30g
Eighteen ingredients. Asiaticoside, betaine and blue tansy oil in a light, soothing ampoule.
Asiaticoside, a compound found in centella asiatica, sits fifth in the list, followed by betaine for hydration and blue tansy oil, which gives the ampoule its blue tint. Allantoin and licorice-derived dipotassium glycyrrhizate complete a classic soothing pairing. Part of our professional line for clinic and spa use as well as home routines. Selected by our in-house pharmacist after a full ingredient review.
What You Feel First
Within 10 Minutes
Skin feels calmer and more comfortable. The light texture absorbs quickly without stickiness.
Next Morning
Skin looks less flushed and feels less tight on waking.
The Concern We Hear Most
"My skin reacts to almost everything. Is this gentle enough?"
The formula is short, which makes it easy to check against your own triggers. One thing to know before you buy: blue tansy oil naturally contains limonene and linalool, which are listed at the end. There is no added fragrance, but if you know you react to these, choose something else. Otherwise, patch test first.
Week by Week
Days 1–3
Skin feels comfortable after cleansing, with less of a tight feel.
Week 1
Skin looks calmer, and the look of redness after cleansing is less noticeable.
Week 2
Dry patches look softer and skin feels more even in texture.
Week 4
With daily use, skin looks calmer and feels well hydrated. Individual results may vary.
The Ingredients Behind It
Asiaticoside
A compound derived from centella asiatica, one of Korean skincare's best-known soothing botanicals. Here it is listed ahead of the hydrators.
Betaine
A naturally derived humectant that helps skin hold water. It adds hydration without a heavy feel.
Blue Tansy Oil
Tanacetum annuum flower oil, known for its natural blue colour. It naturally contains limonene and linalool, so patch test if you are fragrance-sensitive.
Allantoin & Dipotassium Glycyrrhizate
Two classic soothing ingredients; the second is derived from licorice root. Together they help soothe the appearance of irritated-looking skin.
Skin Type Fit
More Than a Hydrating Ampoule
In the treatment room, a short, soothing ampoule is a practical step to calm the look of skin after a facial. At home, it layers under any moisturiser, morning and night.
When you want fewer ingredients doing a clear job, this is the ampoule.
Why Our Pharmacist Chose This
"For reactive skin, a short ingredient list is a feature. Asiaticoside, allantoin and licorice-derived dipotassium glycyrrhizate are reliable soothing choices."
