The weather has finally started to indicate that spring is imminent, and perhaps you, too, are fantasizing about the wardrobe and beauty swaps you'll be making in the coming weeks. Your big, cumbersome jacket will be tucked out of sight and a streamlined, lightweight skincare routine will emerge, wherein Youth to the People's new serum is a perfect fit.

The new Retinal + Niacinamide Youth Serum is a singular product that can replace several steps of your skincare routine — your retinal cream, hyaluronic acid serum, and vitamin C — all in one fell swoop. And in the interest of a rejuvenated spring-ready complexion, InStyle readers get an exclusive 20 percent off discount on the serum with code INSTYLE20.

Not every serum can replace so many products, but Youth to the People's is literally jam-packed with practically every ingredient you could ask for in a skincare product: retinal, ceramides, niacinamide, hyaluronic acid, vitamin E, and more. What you get is a potent and effective product that targets signs of aging, fades hyperpigmentation, evens out complexions, minimizes pores, and provides long-lasting, deep hydration.

According to the brand, the soothing ingredients cocooning the retinal, a more potent version of retinol, will avoid the typical irritation associated with the potent active ingredient. Still, the best practice with a retinal is to first patch test on your arm, and if there is no irritation, introduce it slowly into your routine.

I have been occasionally using the Retinal + Niacinamide Youth Serum since Youth to the People gifted it to me two weeks ago. I can't speak to long-term benefits, but it absorbed so quickly and seamlessly that I forgot I had it on. A couple of times, I layered a moisturizer on top (because my skin is still dry and yet to be spring-ready), and I experienced no pilling or stickiness. Nights when I use the serum, I notice my skin feels calm. The next morning, I look supple, hydrated, and glistening. Some mornings, my complexion looks so good that I hold off on doing my usual skincare routine until the afternoon.

Head to Youth to the People to get your Retinal + Niacinamide Youth Serum for 20 percent off with code INSTYLE20 until March 14.

The first morning I tried the new Summer Fridays Dream Oasis Serum, I woke up very tired — I had been tossing and turning the night before with a bilateral charlie-horse situation — and my skin looked sullen. I didn’t expect anything dramatic, that’s not the vibe of a gentle, hyaluronic-acid serum. However, after splashing my face with cold water, I rubbed a pump of the gel-like serum into my face — directions say, ‘Smooth over cleansed, damp skin (which is the proper way to apply most serums wi
