Read AuditThe 500 Dalton Rule
Molecules larger than 500 Daltons cannot penetrate the stratum corneum without mechanical or chemical disruption. This renders 90% of topical collagen and high-molecular-weight hyaluronic acid serums biologically inert on the surface.
We track the molecular weights of all popular active ingredients to separate systemic efficacy from localized hydration.

Clinical Realities vs. Marketing Claims
| Marketing Claim | Clinical Reality | Evidence Base |
|---|---|---|
| "Medical Grade" Skincare | An unregulated marketing term with no FDA legal definition. | FDA Title 21 |
| Topical Collagen Builds Collagen | Molecule size (300,000 Da) completely prevents penetration. Acts only as humectant. | Bos & Meinardi (2000) |
| Pores Can Open and Close | Pores lack musculature. Temperature changes sebum viscosity, not pore aperture. | Dermatol Surg (2016) |
| Chemical vs Physical SPF | Both types primarily absorb UV rays and convert to heat. "Physical" only scatters ~5%. | Cole et al (2015) |

Frequently Audited Claims
Does collagen in skincare work? +
No. Topically applied collagen molecules are too large (~300,000 Daltons) to penetrate the epidermis. They act solely as a surface humectant, temporarily trapping moisture, but do not integrate with or stimulate your own dermal collagen.
Are chemical sunscreens endocrine disruptors? +
Current human clinical data does not support this claim. While some organic UV filters show weak estrogenic activity in isolated cell cultures (in vitro) or in animal models fed massive doses, the absorption rates through human skin are too low to cause systemic endocrine disruption.
Do I need a dedicated eye cream? +
Usually no. The skin around the eye is thinner, but it responds to the same active ingredients. Eye creams are typically just reformulated facial moisturizers—often with lower concentrations of actives and smaller, higher-priced packaging.
