Advanced Brightening Care for Dark Spots, Dullness and Uneven Tone
Augustinus Bader The Vitamin C Serum is a next-generation brightening and antioxidant treatment designed to visibly improve dullness, dark spots, uneven tone and signs of environmental stress without compromising skin comfort.

Loshen & Crem’s Recommendation
The Vitamin C Serum is an excellent choice for anyone who wants the visible brightening benefits of vitamin C but has struggled with formulas that feel irritating, sticky or difficult to layer.
Because this formula uses stable ascorbyl glucoside rather than pure ascorbic acid, it offers a gentler approach to daily antioxidant care while still targeting dark spots, uneven tone and dullness.
For normal or combination skin, pair it with Augustinus Bader The Cream. For dry, depleted or seasonally stressed skin, follow with The Rich Cream to seal in moisture and support the skin barrier.
Although the serum can be used morning and evening, the morning application is especially important. Follow with broad-spectrum sunscreen to provide complete daily protection against UV exposure and help prevent the appearance of new pigmentation.
Consistency matters more than applying a large amount. Two pumps morning and evening are sufficient.
