What the brand claims
In the brand’s own words, quoted as written.
“The Retinol 0.5 Oil features 0.5% pure retinol suspended in a rich blend of squalane and vitamin E to help improve the appearance of deep wrinkles, uneven texture, and loss of firmness. Formulated for all skin types, especially those accustomed to retinol, it supports smoother, more resilient skin with a naturally luminous tone over time.”
