Bioderma Sébium Gel Moussant On your shelf ✓
Our read, in one look
Lactic acid is the reason to consider this cleanser, with Xylitol behind it.
The case for it
- Lactic acid, moderate evidence for hydration
- Xylitol, moderate evidence for hydration
- No alcohol, silicones or parabens
Mind this
- Sunscreen the next day, acids leave skin more sun-sensitive
- Add it on its own for a week or two, so you know what your skin is answering to
Bioderma Sébium Gel Moussant is a cleanser built around Lactic acid and Xylitol. It leans strongest on hydration. Best suited to dry, normal and combo skin. Go slow: the active is potent enough to irritate if overused.
Skip it if your barrier is already sensitised or compromised: the acids can sting broken or over-exfoliated skin.
The formula, drawn
Every ingredient in label order, coloured by the job it does here.
4 of the 20 sit above the 1% line. The other 16, hatched, are each under 1%. Widths show the ORDER on the label and nothing else: the label never discloses amounts, so we never draw them.

What it delivers
How it feels A gentle wash that lifts the day away without leaving skin tight or squeaky. (estimated from the formula)
What's in it that matters
AHA that provides gentle exfoliation and some humectant effect; generally milder than glycolic but still pH-dependent and potentially irritating.
Sugar alcohol humectant that can increase skin hydration and may support a healthy skin microbiome.
How to use it
In the evening, and not every night: 2–3 times a week is plenty. Follow with a moisturiser, and wear sunscreen the next day.
Keep it away from
- Retinoids (retinol, tretinoin)
- Benzoyl peroxide
- Other exfoliating acids the same night
Where it acts
The same cross-section as our 500 dalton page, with this formula's actives on the layer each one works on. Depth is the anatomy's, never an ingredient's.

Against the average cleanser
It scores lower than the median cleanser on barrier repair, hydration and oil control.
On brightening and anti-aging it is level with the median, so that is not what sets it apart.
A median, not an average: one unusual formula should not move the middle. The numbers are the same 0 to 10 reads the comparison pages use.
The full ingredients list, decoded
Every ingredient on the label, in the order it appears (highest amount first). We link the 11 our library knows, name what each one does, and flag anything that can irritate or clog. The rest we leave plain, nothing is hidden.

Worth knowing: Lactic acid, Xylitol sit below that line. They are in there, and the label does not tell you how much. That is not the same as saying it is too little to matter.
