About Glowmeter

What we do

Glowmeter is an independent, public-interest price tracker for the cosmetics sold on Olive Young (Korea, US, and Global storefronts). We record the time-axis price curve for every SKU we observe and pair it with cross-merchant snapshots so shoppers can verify whether a "sale" is actually a discount and whether today's "lowest price" really is lower than the 30-day average. We have no affiliation with Olive Young or any cosmetics brand.

Data sources

• Olive Young KR / US / Global — public product pages, observed directly (5-min hot / 1-h warm / 24-h daily tiers)
• Naver Shopping — cross-merchant snapshots for the same SKU
• MFDS (Korean Ministry of Food & Drug Safety) — public cosmetic-report dataset (ingredients, manufacturer mapping)
• freetsa.org TSA — RFC 3161 timestamp anchoring of our daily Merkle root (tamper-evident integrity)
