Tetrapeptide-30 FAQs
Common questions about this ingredient in skincare.
What is Tetrapeptide-30?
It is a synthetic four-amino-acid peptide, Pro-Lys-Glu-Lys or PKEK, used in topical formulas for uneven tone and visible discoloration.
How does Tetrapeptide-30 work?
It helps modulate UV- and inflammation-related signaling from keratinocytes, including pathways that can stimulate melanocytes and melanin production.
Is it a direct tyrosinase inhibitor?
Its best-described action involves reducing upstream inflammatory and pigmentation signals, although tyrosinase-related changes have also been observed.
Can it help post-blemish marks?
It may support gradual improvement in visible post-inflammatory discoloration, especially when paired with gentle blemish care and daily sunscreen.
Can Tetrapeptide-30 treat melasma?
It is not an approved melasma treatment. Persistent or recurring pigmentation should be evaluated by a dermatologist.
How long before results are visible?
Tone-evening products usually require consistent use over several skin-renewal cycles. Results vary with concentration, formula, sun exposure, and the cause of discoloration.
