The Sente Defense C Serum with HSA offers an antioxidant treatment which is designed to brighten, firm, and protect.
 
This advanced formula features patented Heparan Sulfate Analog (HSA) technology combined with 20% stabilised Vitamin C and Vitamin E. Together, these ingredients are associated with supporting collagen health, improving skin tone, and aiding in the defense against visible signs of aging caused by environmental stressors.
 
This serum helps the skin to feel smoother, appear more radiant, and is better equipped to face daily challenges.  Formulated for all skin types, including sensitive, it's particularly beneficial for those aiming to revive dull, uneven, or stressed skin without causing irritation.
 
After cleansing, apply 1–2 pumps to the face and gently massage in. Use morning and night. Allow the serum to fully absorb before moving on to the next step in your routine.
