Which retinol strength is best for wrinkles?Updated a year ago
In our experience, retinaldehyde hits the sweet spot between strength and gentleness. Research shows that it offers the same anti-aging effects as tretinoin, but without irritation.
Our clients show incredible results, even when they’ve previously used stronger retinoids. This is probably because retinal is significantly less likely to irritate the skin. Inflammation can trigger oxidative stress that contributes to premature aging, so in a way, retinaldehyde actually addresses wrinkles much like pure retinoic acid would, but without potentially contributing to further inflammation.
The skin only converts as much retinal as it can handle, which has an attenuating effect on inflammation. The remainder can then be stored in the skin, for conversion at a later time when the skin can handle it.
Ultimately, any retinol can help your skin appear younger and smoother, but retinal is our favorite by far.
