The patient who switches every six weeks
A version of this conversation happens in clinic almost weekly;
Someone comes in frustrated. They've tried everything. Three different vitamin C serums. Two retinols. Four different moisturisers. They've spent hundreds of euros over the past year and their skin doesn't look any different.
I always ask the same question. How long did you use each one before you switched? The answer is almost always four to six weeks.
Skin renewal takes around 28 days at best, and slows as we get older. To see meaningful change in pigmentation, fine lines, firmness, or texture you need three to six months of consistent use. Sometimes longer. Six weeks barely qualifies as a warm-up.
The patient who switched every six weeks didn't have a product problem. She had a consistency problem. And once she committed to one routine for six months, her skin transformed. Same products other people had been using for years. The difference was time.
