Higher % can irritate your skin real quick.
Start low and see how your skin reacts.
GHK-Cu hits even at low concentrations.
0.2% max for most DIY mixes.
Too strong and your skin might not like it.
Consistency matters more than pushing the dose.
Low dose, long run = better results.
Hyaluronic acid just helps with delivery and hydration.
Some people even go lower like 0.05%.
Don’t overdo it thinking you’ll get faster results.
Skin care is more about patience than blasting doses.
GHK-Cu is strong, treat it like it is.
Better to build up than start too high.
Most commercial serums stay in that low range anyway.
Higher % doesn’t equal better skin.
