K-Beauty brand KSecret is launching its skincare products online and in stores at Ulta nationwide, with the eight-product Ulta assortment built around retinal, a vitamin A derivative. The brand's products are already sold in more than 500 Ulta locations following an earlier Costco debut this year.

Why it matters

Retinal is a vitamin A derivative that is often compared with retinol, a long-established skincare ingredient, and the brand claims it works 11 times faster. A broader national retail rollout puts retinal-based products within reach of more shoppers, though the speed claim comes from the brand and is not an independent finding.

The figures come from the brand's own launch details and distribution reporting, not from a clinical trial or independent study. The speed comparison of retinal against retinol is the brand's claim and is not backed by published testing in the source.

Health Landscape

Retinol has been a mainstay of over-the-counter skincare for decades, and retinal sits in the same vitamin A family. Its positioning as a faster-acting option reflects a wider shift in beauty toward stronger, ingredient-focused products sold through mass retail.

If you are considering a retinal or retinol product, it is worth discussing with your dermatologist or physician, especially if you have sensitive skin, are pregnant, or use other active treatments. Stronger vitamin A derivatives can cause irritation, so starting with a lower strength is a conversation to have with a clinician.

The takeaway

Retinal is a vitamin A derivative that is now available on national retail shelves, but its faster-acting claim comes from the brand rather than independent research. Check with a dermatologist before adding a stronger retinoid to your routine.
