How it works
Retinal Skin Booster Serum 150ml is a serum built on Retinal, retinaldehyde, a faster-converting retinoid step above retinol, named 28 of 65 entries on MEDITHERAPY's own manufacturer INCI for this formula. Niacinamide runs alongside it, the brightening and barrier-support active, and the rest of the list rounds out a MEDITHERAPY formula built for this format rather than a stripped-down version of it. It takes after toner and before moisturizer, and the serum format is the reason it behaves the way it does once it is on skin. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on.

Key actives
Retinal
Retinal is Retinaldehyde, a faster-converting retinoid step above retinol. It appears at position 28 of 65 on MEDITHERAPY's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Niacinamide
Niacinamide is The brightening and barrier-support active. It appears at position 9 of 65 on MEDITHERAPY's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Adenosine
Adenosine is The wrinkle-care active recognized in Korea's own cosmetic functional-ingredient system. It appears at position 19 of 65 on MEDITHERAPY's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Sodium Hyaluronate
Sodium Hyaluronate is A hyaluronic form working at the surface. It appears at position 24 of 65 on MEDITHERAPY's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Is the Retinal Skin Booster Serum 150ml sold here MEDITHERAPY's Korean-market formula?
Yes. What ships is MEDITHERAPY's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the Retinal Skin Booster Serum 150ml go in a routine?
It takes after toner and before moisturizer. That placement follows from what a serum is, not from anything unusual about this specific unit. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on, so moving it earlier or later in a routine works against the format rather than with it.
What does Retinal do in this serum?
Retinal is Retinaldehyde, a faster-converting retinoid step above retinol. It appears at position 28 of 65 on MEDITHERAPY's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Does the Retinal Skin Booster Serum 150ml contain fragrance?
No. Parfum and fragrance do not appear anywhere on the manufacturer's own ingredient list for this formula, which is one reason it reads as a shorter, calmer list than a heavily scented formula in the same category.
How does buying the Retinal Skin Booster Serum 150ml here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market MEDITHERAPY release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
