Copper Peptides Causing Skin Problems? Here’s What’s Actually Happening | Derm Explains

Summary

Dermatologist Dr. Shereene Idriss explains that “copper uglies” is an internet-coined phrase, not a medical diagnosis. Redness, peeling, breakouts, or burning after starting a copper-peptide product do not automatically mean copper itself is responsible. She recommends considering your entire routine, your skin’s condition before you started, and the product’s full formula.

Practical skincare guidance

• Separate copper peptides from pure vitamin C (L-ascorbic acid). They may neutralize one another, though the speaker says evidence is limited. If using both, apply pure L-ascorbic acid in the morning and copper peptides in the evening.
• Other forms of vitamin C may be compatible. The speaker says vitamin C derivatives such as tetrahexyldecyl ascorbate, ascorbyl glucoside, and sodium ascorbyl phosphate can be used with copper peptides.
• Don’t combine benzoyl peroxide and copper peptides in the same routine. Because benzoyl peroxide is a strong oxidizer, the speaker advises using them at different times. She suggests using benzoyl peroxide as a wash-off product, applying it briefly and rinsing thoroughly.
• Azelaic acid can generally be used with copper peptides. The speaker says there is no strong clinical evidence that the two cancel each other out.
• Introduce new products cautiously. Try a new product on its own for an evening before combining it with the rest of your routine. Be especially careful if you also use exfoliating acids or retinoids.
• Don’t add copper peptides to already irritated skin. If your skin barrier is sensitive or compromised, simplify your routine and let your skin settle before introducing another active. The speaker recommends two to three weeks of simple care in this situation.
• Avoid starting several new products at once. Adding them one at a time makes it easier to identify what your skin tolerates.
• Check the full ingredient list, not just the product label. A serum may also contain exfoliating acids, essential oils, fragrance, or other potential irritants. Copper-peptide concentrations can also vary.
• Pay attention to how your skin responds. The speaker says burning, persistent irritation, or a rash should not be treated as a necessary “purging” phase. Copper peptides do not cause a skin-cleansing process.

Injectable copper peptides and evidence

• The speaker distinguishes topical products from injectable GHK-Cu and cautions against assuming they raise the same safety questions.
• She says injectable GHK-Cu is not FDA-approved and raises concerns about uncertain manufacturing standards and product quality. She refers to an investigation that reportedly found contaminants in some injectable products.
• She considers copper peptides promising but not proven or magical, and says more rigorous clinical studies are needed for topical use. She describes retinoids as a better-established option for skin tightening.
