Tretinoin · The approved retinoid behind most "anti-ageing" claims
A prescription medicine with decades of evidence — and the standard other skin products are measured against.
Revisado médicamente por Bernard Garcia, MD
Qué es
Tretinoin is a prescription retinoid FDA-approved for acne and, in specific formulations, for fine wrinkles and photodamage. It has the strongest evidence of any topical for skin ageing and is the benchmark against which peptide creams are usually compared.
Cómo funciona
Tretinoin binds retinoic-acid receptors, increasing cell turnover and collagen production over months. Irritation is expected early; sun sensitivity requires protection. It is contraindicated in pregnancy.

Preguntas frecuentes
Why is a retinoid on a peptide site?
Because it is the honest comparison for skin peptides like GHK-Cu: a prescription with strong evidence versus cosmetics with modest evidence.
Is over-the-counter retinol the same?
No. Retinol is a weaker precursor available without prescription.
Does Vitrex prescribe it?
No. A provider may consider it after intake; that is their decision.
