Studies show, when formulated properly, a 20% concentration of L-ascorbic acid provides the maximum amount of Vitamin C readily absorbed by the skin. Now formulates with AOX+ advanced antioxidant technology, Skinceuticals Serum 20 combines Ferulic Acid with pure Vitamin C at the precise pH and concentration to enhance antioxidant performance and deliver maximium levels of L-ascorbic acid. Designed to restore and protect healthy looking skin, this light weight and fast-absorbing serum neutralises free radicals, defends against environmental damage, and helps prevent premature signs of ageing. Ideal for normal to oily skin.
AOX+ advanced antioxidant technology
• combines ferulic acid with pure vitamin C to enhance antioxidant performance
• reduces the appearance of fine lines and wrinkles, neutralizes free radicals, provides environmental protection, and helps stimulate collagen synthesis
• using Duke-patented vitamin C technology, shown to deliver the highest levels of L-ascorbic acid to the skin
Reservoir effect
• once absorbed, can’t be washed or rubbed off, remaining protective for up to four days
— an excellent addition to sunscreens
• photoaged or photodamaged skin
• oily skin
• erythema
• poor skin elasticity
• hyperpigmentation
• beginning 30 days before and/or 7-10 days after invasive or non-invasive rejuvenating procedures
APPLICATION
Once daily using fingertips, apply 4-5 drops of Serum 20 to face, neck, and chest.
L-ASCORBIC ACID (20%)
• considered one of the most important water-soluble anti-oxidants
• inhibits UVA and UVB radiation-induced damage
• photoprotective capabilities
• promotes collagen synthesis
• anti-inflammatory properties
FERULIC ACID
• ubiquitous plant antioxidant
• neutralizes free radicals known as "superoxide," "hydroxyl radical" and "nitric oxide"
• suppresses radiation-induced oxidative reactions
• acts synergistically with other antioxidants, improving their potency
• absorbs UV (approved sunscreen in Japan)
• anti-inflammatory properties
• easily absorbed by the skin
HYALURONIC ACID (SODIUM HYALURONATE*)
• natural humectant with excellent water-binding capabilities
• capable of attracting and retaining 1,000 times its own weight in water
• assists as a carrier for other agents to be delivered below the skin’s surface
• ability to retain water gives immediate smoothness to rough skin
• occurs naturally in the dermis
• allows the epidermis to achieve greater suppleness, proper elasticity, and turgor (*sodium hyaluronate is the sodium salt of hyaluronic acid which occurs naturally; we use sodium hyaluronate because it is water soluble)
ZINC
• accelerates wound healing
• offers protection against UVB radiation
• promotes collagen synthesis in the dermis (useful in acne treatments since it lowers sebaceous secretion)
BIOFLAVONOIDS
• possess antioxidant properties that neutralize free radicals
• antimicrobial activity and anti-inflammatory benefits
