TIRTIR SOS Serum is a 50 ml gel serum with polyglutamic acid, hyaluronic acid, centella, chamomile, panthenol and allantoin, plus three peptides and adenosine. It hydrates and calms skin that feels stressed or looks red, leaving it soft, bouncy and comfortable.
What it does
Polyglutamic acid and sodium hyaluronate hold water at the surface of the skin for a cushioned, hydrated feel. Centella, chamomile, licorice, panthenol and allantoin soothe skin that feels irritated. Three peptides (acetyl hexapeptide-8, copper tripeptide-1 and palmitoyl pentapeptide-4) and adenosine are included for the look of fine lines.
Why we chose it
We chose it as a calming, hydrating serum first: our box leads with polyglutamic acid for moisture, and no fragrance is listed. TIRTIR describe it as vegan and free from alcohol and silicones. It follows TIRTIR Milk Skin Toner well.
Best for
- Skin that looks red or feels sensitised
- Dehydrated skin that feels tight
- Skin stressed by retinoids or exfoliating acids
- Blemish-prone or oily skin that wants calm without heaviness
- A simple hydrating step, morning and evening
Not ideal if
- You react to plant extracts: it contains witch hazel, rosemary, anise, green tea and others
- You want a targeted treatment for lines or dark spots: this is a calming, hydrating serum first
- Your skin is very dry: follow with a richer moisturiser
Key ingredients
- Polyglutamic acid and sodium hyaluronate: hydration and a bouncy feel
- Centella, chamomile and licorice extracts: soothe skin that feels irritated
- Panthenol and allantoin: comfort
- Three peptides and adenosine: a supporting extra for the look of fine lines, not the main reason to choose it
Texture and finish
A gel-like serum that absorbs in seconds and leaves skin refreshed, with no sticky or greasy finish.
Where it goes in your routine
After cleansing and toner, before moisturiser, morning and evening. TIRTIR suggest 2 to 3 drops for the face, then sunscreen in the morning.
What to expect
Skin feels hydrated and calmer straight away. Comfort and a more settled look build with steady daily use, especially alongside a gentle routine.

- In the morning, finish with sunscreen.
- It has no retinoid or exfoliating acids, so it can sit in the same routine as those, on evenings your skin feels stressed.

Is it suitable for sensitive skin?
It depends on your skin. TIRTIR list sensitive skin, and there is no fragrance or essential oil in the listed ingredients. It does contain several plant extracts, including witch hazel, rosemary and anise, which some reactive skin dislikes. Patch test first.
Is this an anti-ageing serum?
Not primarily. It contains three peptides and adenosine for the look of fine lines, but we chose it for hydration and calm. If lines are your main goal, a dedicated treatment will do more.
Can oily or blemish-prone skin use it?
Usually, yes. It is a light gel that TIRTIR describe as absorbing in seconds without a greasy finish, and they list acne-prone skin among the skin types it suits. It is a calming, hydrating step, not a breakout treatment.
Can I use it with retinoids or exfoliating acids?
Yes. There is no retinoid or exfoliating acid in the formula, so it adds a hydrating, calming layer on the evenings you use them. If your skin is already burning or peeling, pause the active rather than adding more layers.
What does polyglutamic acid do?
It is a humectant: it holds water at the surface of the skin for a cushioned, hydrated feel. It is the ingredient our box leads with, alongside sodium hyaluronate further down the list.
