What is the difference between ‘Microblading’ and ‘Digital Machine’ SPMU?

Digital machines such as 'The Pro Pad' Will create thee most crisp natural hairs using A single needle that penetrates at the same depth into the skin every single time with the exact same pressure and precision this will give longer lasting more even coverage and colour retention results of up to 2/3 years. Micro-blading is A hand held blade with 4-5 slanted needles manually engraved into the skin some times penetrating 'too deep' into the skins layers. Human pressure can never be the same with each incision, therefore there is an inconsistency throughout the Brow sometimes causing A uneven effect of colour and fading, this type of method usually only lasts 6 to 12 months.
