Combine lactic acid and panthenol: repair after exfoliating

Exfoliate and repair in the same routine. Lactic acid removes, panthenol restores. It's one of the simplest combinations to maintain, and one of the best suited for sensitive skin.

Why lactic acid is the first choice

It's the gentlest of the alpha-hydroxy acids. Its molecule, larger than that of glycolic acid, penetrates more slowly and causes less irritation. It's also part of the skin's natural moisturizing factors, which is rare for an exfoliant.

This dual property gives it a unique profile: it exfoliates and hydrates. For sensitive skin, it's the acid that causes the fewest problems, and often the only one that can be used without a long acclimation period.

Panthenol as a repair agent

It strengthens the skin barrier by providing a humectant that, converted into vitamin B5, participates in the metabolism of surface cells. Its effect on comfort can be felt in a few days, whereas acid takes weeks to show its work.

It also helps reduce irritation that follows acid application. It's an ingredient with no inherent tolerance threshold: it can be used morning and evening from the first day, without ramping up.

The routine, day by day

Acid evenings: cleanse, apply lactic acid to dry skin, wait twenty minutes, then apply panthenol, and finally moisturizer. Non-acid evenings: cleanse, apply panthenol, then moisturizer. Mornings: cleanse, apply panthenol, moisturizer, and sunscreen.

Start with two acid applications per week. Needs vary: oily skin may tolerate three, sensitive skin may be limited to one. Panthenol, however, maintains its rhythm.

For which skin types

Sensitive skin: this is the reference combination; no other combines an exfoliant and a soothing agent as well tolerated. Dry skin: lactic acid is better accepted here than its cousins. Combination skin: same protocol with more frequent use.

Oily skin with imperfections: a salicylic acid will work better, as its lipophilic nature allows it to reach inside the pore. Panthenol is still useful in this case too.

The effects, and their timeline

Comfort in a few days thanks to panthenol. More even skin texture in three to four weeks. Brighter complexion in six to eight weeks. These are progressive effects, and judging them before six weeks means measuring something else.

These active ingredients do not act on established wrinkles or old pigmentation. What they improve is the surface condition, and that's already what changes the overall appearance of a face the most.

What can be added

Hyaluronic acid can be included without counting as an additional active ingredient. A ceramide cream in the evening further strengthens the barrier. However, a second acid or a retinoid on the same evening should be avoided.

The lactic acid AHA peel covers the exfoliating part, and the gentle prebiotic mist complements it for comfort. Our lactic acid and panthenol fact sheets detail the concentrations.
