⚠️ Active ingredients to use with caution

Even some “good” ingredients can be too harsh for sensitive skin, especially in high concentrations:

• Retinoids
• Strong AHAs (e.g. glycolic >10%)
• Denatured alcohol

Better to introduce them gradually and only if they are well tolerated.

Expert opinion

"When we talk about sensitive skin, the rule is to choose a few targeted actives. It's better to focus on ingredients that hydrate, soothe, and strengthen the barrier, rather than layering too many products without a clear purpose."
