Hardings entertaining and inspiring speeches highlight the importance of tenacity in the face of disaster, a crucial lesson for people with and without disabilities
Why they work together: Copper peptides enhance wound healing and skin regeneration Support retinol's collagen-boosting effects Anti-inflammatory properties counter retinol irritation Both stimulate collagen from different pathways Important consideration: Some research suggests using copper peptides and retinol at different times (AM vs PM) for optimal results, though many formulations combine them successfully

[10] Diagnosis is not always straightforward and can be challenging and can take up to several years to receive a diagnosis from the onset of symptoms and almost 60% of those affected are misdiagnosed or not initially diagnosed at all
After opening commercial serum Once opened (seal broken): Air exposure begins Bacterial contamination possible Oxidation accelerates Shorter shelf life Track opening date Shelf life after opening: Why packaging matters: Airless pump: Minimal air contact, longest life Dropper: Some air exposure, moderate life Jar: Maximum air exposure, shortest life Finger contamination risk (jar) Best practices after opening: Refrigerate after opening (extends life) Close tightly after each use Don't contaminate (no fingers in product) Use within 6 months ideally Note opening date on bottle Signs commercial serum degraded: Color change (darkening, blue-green tint) Smell change (rancid or off odor) Texture change (separation, clumping) Reduced efficacy (no longer works) Irritation (preservatives depleted, bacteria) When to discard: Past expiration date + 3-6 months opened Any signs of degradation above Unusual smell or color Product separated and won't remix Skin irritation develops Commercial vs DIY serum stability Commercial serum advantages: Professional preservative systems pH buffered correctly Antioxidants included Tested stability (12-24 months unopened) Quality assurance DIY serum challenges: No professional preservatives (or inadequate) pH optimization difficult Limited antioxidant protection Short shelf life (1-2 weeks refrigerated) Bacterial contamination risk Comparison: When DIY acceptable: Make small batches (1-2 weeks supply) Use immediately Refrigerate always Accept short shelf life Understand contamination risk When commercial better: Want convenience Need longer shelf life Travel frequently Don't want frequent preparation Value safety/stability See DIY GHK-Cu serum recipe for home formulation
