The Science Behind Age IQ: What SIG-1273, TC3-Armor, and SAL-14 Actually Do
Age IQ isn’t built around one active ingredient, it’s built around three patented ingredients, each doing a different job. That’s the part most people miss when they hear the ingredient names without ever learning what any of them actually do.
How Each Ingredient Does Its Job
Age IQ Night and Day Cream is built to work around the clock, but not because one ingredient is doing everything. Each of the three patented actives is handling a specific job, and understanding what each one does is the real reason the formula works the way it does.
SIG-1273 works at a cellular level. Developed by Signum Biosciences over 1,273 formulation attempts (the ingredient’s namesake), it binds with skin cells and functions as an antioxidant, helping combat the oxidative stress that accelerates visible aging over time. This is the ingredient doing the deepest, most foundational work in the formula.
TC3-Armor is built for defense. It’s formulated to help protect skin against daily environmental stressors, the accumulated exposure your skin deals with from pollution and city living, rather than repairing damage after the fact. Think of it as the ingredient standing between your skin and everything the day throws at it.
SAL-14 is where cell renewal happens. Built around bidens pilosa, a botanical that’s been studied for effects that resemble retinol, it supports skin renewal without the irritation retinol can cause, particularly useful for anyone with sensitive skin who’s avoided retinol for that reason.
Together, that’s antioxidant protection, environmental defense, and cell renewal, three distinct mechanisms working in the same formula, rather than one ingredient trying to do a job it wasn’t built for.
A 24-Hour System, Not Just a Routine
Day and night aren’t just different times to apply skincare, your skin is doing different work during each one, and Age IQ is built around that difference rather than using one formula for both.
During the day, skin is in defense mode, dealing with UV exposure, pollution, and environmental stress in real time. That’s where TC3-Armor and SIG-1273 do their heaviest lifting, protecting against daily damage as it happens, while SAL-14 supports renewal throughout the day.
At night, skin shifts into repair mode, without sun or pollution working against it, this is when real renewal actually happens. The Night Cream’s richer, mask-like texture is built for that shift, staying on skin through a full night’s sleep so the same three ingredients have uninterrupted time to do restorative work instead of competing with a full day of exposure.
Used together, morning and night, you’re not applying the same product twice, you’re supporting two different phases your skin goes through every single day.
