About SOS Serum

Overview

SOS Serum is a lightweight serum from TIRTIR. The formula is built mainly around hydration and soothing. The ingredient list runs to 39 ingredients, each broken down in full below.

Texture and finish

By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Glycerin, Butylene Glycol and Betaine, humectants that pull water into the upper layers of skin rather than sealing it there.

What the formula does

Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Butylene Glycol, Betaine and Panthenol.

Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Centella Asiatica Leaf Water, Cetyl Ethylhexanoate, Chamomilla Recutita Flower Extract and Centella Asiatica Extract.

Who it suits

On richness alone it suits Balanced, Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.

What it does not target

The formula contributes little or nothing on antioxidant protection, oil control, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.

What is not in it

Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.

Where it fits in a routine

It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.

This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.

What to layer it with

Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.

Compatible with

  • Vitamin C (L-ascorbic acid)
  • Retinoids (retinol, retinal)
  • AHAs (glycolic, lactic)
  • BHA (salicylic acid)
  • PHAs (gluconolactone)
  • Benzoyl peroxide
  • Azelaic acid
  • Copper peptides
  • Bakuchiol
  • Niacinamide
  • Hyaluronic acid
  • Ceramides
  • Signal peptides
  • Panthenol
  • Sunscreen

Nothing in this formula belongs to a group our rules can put in conflict, so it layers freely. Order still matters — thinnest texture first.

Where it fits in a routine

Morning Evening
  1. Cleanse
  2. Toning
  3. Treat
  4. Moisturise
  5. Protect

This product is the "Treat" step.

  • Apply to clean, dry skin and give it a minute to absorb before the next layer.
  • Introduce one new treatment at a time so you can identify what is working.

Safety and suitability

Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.

Pregnancy and breastfeeding
Nothing in this formula is on the standard pregnancy-caution list. That is not clearance — ask your doctor about anything you use daily.
Fungal acne (malassezia)
2 ingredients could feed malassezia: Polyglyceryl-10 Laurate, Polyglyceryl-10 Myristate. That is about the yeast's food supply, not a prediction that you will break out.
Sensitive and reactive skin
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
