Neutrogena® Hydro Boost® city shield hydrating lotion SPF 25. At Neutrogena, we know that hydration is the foundation for healthy-looking skin. However, a busy life and challenging environments such as pollution, harsh weather and sun exposure can deteriorate both skin's hydration levels and skin's natural protective shield. This can cause premature skin ageing and loss of radiance. Neutrogena® Hydro Boost® City Shield hydrating lotion SPF 25 boosts hydration, strengthens skin's natural shield and protects against harmful UV rays and pollution for a radiant complexion. Boosts Hydration and strengthens skin's defences: formulated with hyaluronic acid, this lotion not only replenishes skin with a boost of intense hydration, it also strengthens the skin barrier day after day so it can actively defend against external aggressions. Helps defend skin against pollution: its formula containing antioxidant helps protect the skin from pollution damage and preserve its youthful glow.
