COMMON QUESTIONS

What is Peptide Skin Complex (4-in-1)?

Peptide Skin Complex contains caffeine, GHK-Cu, tretinoin, and niacinamide in one topical cream. It can target hyperpigmentation, fine lines, and uneven texture.

How do you use Peptide Skin Complex?

Cleanse face and neck thoroughly and pat dry. Apply a thin layer of Peptide Skin Complex to affected areas or entire face once daily in the evening as prescribed.

Tretinoin increases sensitivity to the sun. Always follow with a broad-spectrum sunscreen during the day.

What are the side effects of Peptide Skin Complex?

Common side effects include mild redness or irritation, dryness, peeling, burning, and sensitivity.

When to expect results?

Meaningful improvements in collagen and texture typically take 3–6 months of consistent use. Stopping too early is the most common reason people don't see results.
