The small wrinkles that remain visible even when the face is perfectly rested, that moment when the complexion seems less plump than before… Not really dramatic, but enough to start looking at anti-aging serums with a different eye.
And K-beauty just loves to bring out a slightly different formula just when we thought we had seen it all. COSNORI’s Korean Retinal and PDRN Serum combines two very popular active ingredients in a texture filled with small yellow capsules that melt directly onto the skin.
Retinal and PDRN: two active ingredients to no longer choose between wrinkles and rebound
On the one hand, we find retinal, a vitamin A derivative particularly appreciated in routines that target fine lines, irregular texture and lack of firmness. On the other hand, COSNORI adds PDRN of plant origin, more focused on hydration, comfort and the revitalized appearance of the skin. The duo is quite clever. Because in practice, wrinkles aren’t always the only problem: when skin becomes drier and less plump, they also tend to appear much more present.
Capsules that melt upon application
Above all, the bottle has a very K-beauty feature: its active ingredients are integrated into double capsule technology. The small beads melt on contact with the skin and mix with the serum during application. COSNORI explains that this system helps preserve the freshness and stability of retinal and PDRN until the time they are used. Around it, the formula adds niacinamide, panthenol, squalane and hydrolyzed hyaluronic acid. In other words, this anti-aging serum does not only rely on its anti-wrinkle active ingredient: it also seeks to keep the skin supple, comfortable and well hydrated. And that, when you use retinal, is frankly not a detail.
The anti-aging serum that prefers regularity to overkill
With retinoids, using three times more product has never allowed you to go three times faster (too bad). A small amount of this Korean COSNORI serum is enough in the evening, on clean skin. For skin new to retinal, a spaced frequency remains more comfortable initially, before gradually increasing according to tolerance. Evenings already loaded with exfoliating acids or peels are not necessarily the best for adding another stimulating active ingredient. And the next morning, sun protection obviously remains important.
What is the difference between retinal and retinol?
Retinal and retinol both belong to the retinoid family. Retinal requires one less conversion step before becoming active in the skin. It is therefore particularly appreciated in treatments that target wrinkles and texture. Its tolerance nevertheless depends on the formula and the sensitivity of each skin.
What is PDRN used for in a Korean anti-aging serum?
PDRN has become one of the most popular ingredients in Korean beauty. In this formula, COSNORI uses a plant-based version to support hydration and the revitalized appearance of the skin. It therefore complements the more targeted action of retinal. However, the evidence on topical forms of PDRN remains less numerous than that available on retinoids.
Can we use this Korean serum every night?
It all depends on the skin’s tolerance to retinal. People already accustomed to retinoids will generally be able to use it more regularly. On novice or sensitive skin, a few evenings a week is a gentler approach. The frequency can then change according to skin comfort.
