The Science of Photo-Oxidation
Pure, unrefined botanical oils and active essential extracts are alive. Rich in essential fatty acids, polyphenols, and natural vitamins, they are incredibly effective on the skin — but they are also sensitive to ultraviolet (UV) light.
When natural oils in clear glass or plastic are exposed to ambient sunlight or bathroom lighting, UV rays spark a chemical process called photo-oxidation. This degrades the active compounds, turns beneficial fatty acids rancid, and destroys the soothing power of cold-pressed oils long before you finish the bottle.
Filtering Harmful Light Waves
Amber glass naturally blocks UV light in the 300nm to 450nm range — filtering out blue light and ultraviolet rays that cause oxidation. By keeping light out, amber glass extends the active potency of cold-pressed botanicals without synthetic chemical preservatives.
Why Glass over Plastic Containers
Mass-market skincare brands often rely on clear plastic packaging due to lower shipping costs. However, plastic poses serious compromises for natural botanical formulas:
4 Reasons Amber Glass Superiority
- Zero Microplastic Leaching: Essential oils are natural solvents that slowly degrade plastic walls, leeching micro-compounds into your product. Glass is completely inert.
- Zero Chemical Preservatives Needed: UV filtering allows us to eliminate synthetic stabilizers like phenoxyethanol or parabens.
- 100% Infinitely Recyclable: Glass can be remelted and reused indefinitely without losing purity or quality.
- Apothecary Freshness: Preserves the handcrafted batch quality from our Calgary studio to your vanity.
Our Commitment to Small-Batch Integrity
Because every jar and serum bottle at Luna Fresh is filled by hand in Calgary, using amber glass ensures that the very first drop you apply is as fresh, active, and alive as the day it was made.
When you hold a Luna Fresh amber glass bottle, you are holding a formula protected with intention — honoring traditional apothecary wisdom and modern skin science.
