The difference
Both contain GHK-Cu, BPC-157 and TB-4. KLOW adds a fourth — KPV, an anti-inflammatory peptide. That is the whole distinction.
Which one
The common rule of thumb: GLOW when skin is calm and the goal is firmness and texture; KLOW when inflammation or redness is in the picture (e.g. reactive or rosacea-prone skin), because KPV targets the inflammation side.
Frequently asked questions
Can you switch between GLOW and KLOW?
They share the same three core peptides, so they are commonly described as interchangeable depending on whether inflammation is a factor. Reference information, not medical advice.
