What I Look for in a GHK-Cu Peptide Serum
When I shop for a GHK-Cu peptide serum, I first check the ingredient list and the formula strength. I want a product that clearly states the presence of GHK-Cu and avoids unnecessary fillers that could irritate my skin. I also look for a serum that feels lightweight, absorbs well, and fits easily into my routine.

How I Check Product Quality
I trust brands that are transparent about sourcing, testing, and formulation. If a company explains the concentration, packaging, and usage instructions clearly, I feel more confident in the product. I also prefer serums in dark or air-tight packaging because I want the formula to stay stable and effective for longer.
How I Match It to My Skin Type
I always think about my skin type before buying. If my skin feels dry, I look for a richer hydrating formula. If my skin is oily or combination, I choose a lighter serum that layers well under moisturizer. For sensitive skin, I prefer a gentle formula with fewer active ingredients and a simple ingredient list.
How I Use It in My Routine
In my routine, I usually apply GHK-Cu peptide serum after cleansing and before moisturizer. I like to use it on clean skin so it can absorb properly. I also make sure to follow the instructions on the label and introduce it slowly if I am trying a new product for the first time.
What I Compare Before Buying
Before I make a purchase, I compare price, ingredient quality, texture, packaging, and customer reviews. I do not always choose the most expensive option, but I do look for good value and a formula that seems well made. Reviews help me understand how the serum feels on real skin and whether it layers well with other products.
