With 0.1% Neurosensine, it effectively calms irritation, while amino acids work to minimize visible redness, offering soothing relief. This serum is lightweight and non-greasy, making it ideal for those who prefer a fragrance-free solution. Infused with La Roche-Posay Thermal Spring Water, it deeply hydrates for up to 48 hours, supporting the restoration of the skin barrier. Its hypoallergenic formula is free from parabens and harsh chemicals, making it gentle yet effective for daily care. By locking in moisture, the serum helps to refresh and calm the complexion, restoring a natural glow.
