OUR FORMULATION PHILOSOPHY
DermalLattice™ represents the GSL Science approach to intelligent formulation. Rather than relying on one highly promoted ingredient, our formulas are developed as coordinated systems of peptides, hydrators, barrier-supporting ingredients and complementary actives.
DermalLattice™ is our formulation philosophy—not a single ingredient.
OUR STANDARDS
Our quality process is designed to support product consistency, safety and regulatory readiness.
Ingredient documentation, supplier specifications and batch records.
Stability, compatibility and sensory review during product development.
Testing appropriate to the formula and production stage.
Labelling and product notification prepared with Canadian cosmetic requirements in mind.
Final claims and quality statements should be updated once your manufacturer provides completed test reports and production documentation.

ABOUT GSL SCIENCE
GSL Science began with a simple question: why should customers have to choose between clinical-looking products that feel impersonal and luxury products that provide little explanation of what is inside?
We are building a different kind of skincare company—one that combines thoughtful formulation, premium presentation and clear scientific communication.
Our goal is not to promise that aging can be reversed. Our goal is to help people care for their skin confidently as it changes over time.
DAILY USE
Use a gentle cleanser and pat skin dry.
Apply a small amount of facial serum to face and neck.
Follow with a compatible moisturizer as needed.
Apply broad-spectrum sunscreen during the daytime.
