I didn't start using retinol because a magazine told me to. I started because I ran my finger across my cheek one night while I was taking off my makeup and felt something I hadn't really noticed with my eyes: little ridges. Not deep lines, just a rough, uneven texture that hadn't been there a few years earlier. My skin used to feel smooth under my fingers the way a countertop feels smooth. It didn't anymore. So I bought the Tree of Life retinol serum, mostly because it was inexpensive enough that I wouldn't feel foolish if it did nothing, and I used it most nights for three months before I let myself have an opinion. I'd tried retinol once before in my thirties and gave up after a week because my skin flaked and burned. I was older and warier going in this time, which turned out to matter.
Here's what I'd actually tell a friend if she asked whether it's worth adding to her nightstand. Ten reasons, no fluff, nothing I wouldn't say to her face over coffee.
The bottle that changed my nighttime routine
If you want to see the exact one I've been using, Tree of Life's retinol serum is what's sitting on my nightstand right now. Current price and availability are on Amazon.

This surprised me. I expected to be watching my forehead for changes, but the first thing I actually noticed about the Tree of Life serum was texture, not lines. Around week three, my cheeks stopped feeling like sandpaper under my fingertips at night. By week six I could run my hand across my jaw in the dark and not feel the little ridges that used to catch under my nails. I wrote about that shift in more detail in my long-term review, but the short version is that smoother texture showed up well before anything you'd call a wrinkle improvement.
The fine lines around my eyes softened, not disappeared
I want to be honest about this one because I've read reviews that promise more than any serum can deliver. My crow's feet are still there. They just look softer, less carved in, especially in the kind of overhead bathroom light that used to make me wince. That's a meaningful change for a nightly step, even if it isn't a dramatic one.
A little goes a long way, which kept me from overdoing it
I use about a pea-sized amount of the Tree of Life serum, sometimes less. Early on I made the mistake of using more because I figured faster would be better. It wasn't. My skin got tight and a little flaky along my jaw for almost a week. Once I scaled back to a smaller amount and used it every other night at first, that problem went away and stayed away. These days I could probably use less than I do and still see the same results, which tells me the amount matters more than I gave it credit for at the start.
It's formulated with jojoba oil, so it didn't strip my skin
Some retinol products I tried years ago left my skin feeling raw by morning, like it had been scrubbed too hard. This one has jojoba oil worked into the formula, and I noticed the difference right away. My skin felt fed rather than stripped, even during the first couple of weeks when my face was still adjusting to something new. I didn't need to layer on extra moisturizer just to counteract it, which is what I'd always had to do with harsher formulas in the past.
It's gentle enough that I could build up slowly without giving up
I started at two nights a week. Then three. By month two I was using it most nights without any real irritation. If you're nervous about starting retinol at all, that gradual approach made the difference between actually sticking with it and abandoning it in a drawer after one rough weekend. If you want the full breakdown of how to ease into it, I put together a guide on starting retinol without irritation.
It made my pores look less noticeable, especially on my nose
I have larger pores across my nose and upper cheeks, always have, and I never expected the Tree of Life serum to change how they looked. But smoother surrounding skin makes the pores themselves look less pronounced, the same way a freshly sanded piece of wood shows fewer knots than a rough one. It's an indirect effect, not a direct one, but I'll take it.
One bottle has lasted me a genuinely long time
I use a small amount most nights, and three months in, I'm still working through my first bottle with plenty left. For a product I use almost every day and have no plans to stop, the cost per week has been low enough that I stopped thinking of it as an indulgence and started thinking of it as a regular supply run, the way I think about toothpaste.
It softened a couple of faint dark patches near my hairline
I've had some faint discoloration near my temples for years, mostly from sun exposure decades ago. It didn't vanish, and I wouldn't tell you it did. But it's fainter now than it was in the spring, since I started using the Tree of Life serum, and fainter in a mirror at 7am is the kind of small, honest win I've learned to notice and appreciate rather than dismiss. My sister noticed before I said anything, which told me it wasn't just wishful thinking on my part.
It gave my skin an evenness that made foundation almost unnecessary
On the mornings after a retinol night, my skin looks even enough that I've started skipping foundation altogether and just using a light tinted moisturizer. That wasn't the goal when I started this, but it's become one of my favorite side effects. Less product on my face in the morning because there's less to cover up, and fewer minutes spent at the mirror before I can walk out the door.
It's a reasonable, low-risk way to find out if retinol works for your skin at all
Not every face responds to retinol the same way, and I'd never promise otherwise, no matter how well the Tree of Life serum has worked for mine. But at this price, giving it eight to twelve weeks is a fair way to find out without committing to something pricier first. If you want the unfiltered version of how mine went, warts and all, I wrote it up in this honest review.
What I'd Skip
I wouldn't expect a retinol serum to erase deep, longstanding lines on its own, and I wouldn't layer it with a bunch of other active ingredients in the same week just because early results felt encouraging. I made that mistake once, stacking a new exfoliating acid on top of retinol within days of each other, and my skin let me know about it for a solid week with redness and flaking along my chin. I also wouldn't apply it in the same routine as anything with a strong fragrance, since my skin seemed more reactive to scented products during the first month of adjusting. Introduce one new active at a time, ease in slowly, and give it a real stretch, eight to twelve weeks minimum, before deciding whether it's working for you.
It didn't erase the years. It just made the texture underneath them smoother.
Still deciding? Here's the one on my nightstand
After months of nights with this in my routine, it's the step I'd be most annoyed to run out of. See current pricing and reviews for yourself before you decide.
