Let’s take a closer look at why retinol is such a staple in skincare routines—and then I’ll share my personal review of the Haruharu Wonder Black Rice Night Knight Retinol Serum.
Let’s get started!
What Is Retinol?
Retinol is truly one of skincare’s hero ingredients. What makes it so special is its ability to address a broad range of concerns. Whether you’re worried about fine lines and wrinkles, skin sagging, dullness, uneven texture, dark spots, visible pores, or even blackheads and breakouts—retinol is one of the few ingredients that can tackle almost all of them.
Retinol is actually a derivative of vitamin A, and it has a long history of use in dermatology. Its skincare journey began back in 1943 when it was first studied for treating acne. In the 1980s, scientists discovered that retinol could also reduce visible signs of aging like wrinkles and rough skin texture. Then in 1997, a South Korean cosmetic company became the first to successfully stabilize retinol, which was a huge milestone—it meant retinol could finally be used effectively in over-the-counter products without losing potency.
So, how does it work exactly? The power of retinol lies in its ability to increase skin cell turnover and neutralize free radicals. This dual action encourages collagen and elastin production—both of which are key proteins that keep the skin looking firm, bouncy, and smooth. It also helps shed dead skin cells more efficiently, leaving your skin brighter, clearer, and more refined. As a result, pores appear smaller, dark spots begin to fade, and your skin just looks healthier overall.
But Is Retinol a Miracle Ingredient?
It almost sounds too good to be true—and like everything in skincare, there’s a catch.
While retinol delivers amazing results, it can come with some side effects, especially when you’re just starting out. The most common ones are dryness, peeling, irritation, and sensitivity. That’s because retinol is powerful, and with power comes the need for patience and strategy.
The good news? These side effects are usually temporary and preventable—as long as you introduce retinol into your routine gradually and with care.
How to Start Using Retinol the Right Way
If you’re new to retinol, here are a few essential tips:
🧴 Start with a Gentle Formula
Look for beginner-friendly or low-strength retinol products. A lower concentration (like 0.05–0.1%) is more than enough to see results without overwhelming your skin.
🕓 Introduce Slowly
The golden rule: less is more at first. Start with once or twice per week, and slowly increase the frequency as your skin builds tolerance. It might take a few weeks or even a couple of months—but it’s worth the wait.
🧬 Support Your Skin Barrier
Because retinol speeds up skin renewal, your skin barrier can become more vulnerable. To keep it strong, layer on barrier-repairing products that contain fatty acids, cholesterol, and ceramides.
One product I really recommend is the Haruharu Wonder Black Rice Probiotics Barrier Essence. It features the golden ratio of barrier-strengthening ingredients that keep your skin nourished and protected.
☀️Never Skip SPF
Sunscreen is a daily essential in any skincare routine, but when you’re using retinol, it becomes non-negotiable. Retinol reveals fresh, baby-soft skin cells that are more sensitive to UV rays. Without sunscreen, you risk undoing all the progress and possibly causing more damage.
Also, retinol should only be used at night, since sunlight can break it down and reduce its effectiveness.
Pairing Retinol With Calming Ingredients
Another way to avoid irritation is to choose a retinol product that’s been formulated with soothing, balancing ingredients—which brings us to my review of the Haruharu Wonder Black Rice Night Knight Retinol Serum.
This serum is a perfect example of how to formulate retinol the right way: effective, yet gentle.
Here’s what’s inside:
🔬 Key Ingredients:
-
0.08% Pure Retinol – a low but effective concentration that’s ideal for beginners or sensitive skin.
-
1% Bakuchiol – a plant-based retinol alternative that offers similar benefits (firmness, smoothness, improved tone) but with far less risk of irritation.
-
Fermented Black Rice Extract – rich in antioxidants, helping calm and nourish the skin.
-
Ceramides + Sunflower Seed Oil – these moisturize and reinforce the skin barrier.
It’s designed to gently improve skin texture, tone, and elasticity—all while keeping the skin soothed and hydrated.
🧪 Clinically Proven Results:
After just 2 weeks:
- 12.1% wrinkle reduction
- 39.6% decrease in pore size
- 40% reduction in pore volume
These results are pretty impressive, especially considering it’s such a gentle formula.
Packaging & First Impressions
Let’s talk packaging—it’s gorgeous! The gradient design (soft purple fading to white) is chic and calming, and the lettering gives it a high-end feel. But more importantly, it features an airless pump, which is a must for retinol. Air and light can break down retinol quickly, so this packaging helps maintain full potency until the last drop.
Texture, Scent & Application
The texture is a silky, milky lotion that spreads easily and absorbs quickly. One pump is the perfect amount for my face and neck, which I really appreciate—it makes application super simple.
There’s a slight scent when first applied (from the retinol), but it’s very mild and disappears fast once absorbed. It’s not perfumed or artificial smelling, which I like.
My First Use Experience
After double cleansing and applying my toner, I gave my skin a few moments to dry, then applied one pump of the retinol serum. I carefully avoided the eye and mouth area, and gently massaged it into my face and neck.
My first thought? Wow—it’s so gentle. No tingling, no tightness, no dryness. In fact, it left my skin feeling lightly moisturized, which surprised me because many retinol products can feel drying right away.
I followed up with the Black Rice Probiotics Barrier Essence and my Phyto & 5 Peptide Concentrate Cream to seal everything in.
Two Weeks Later
After easing into it, I’ve been using the serum every night for the past two weeks—and here’s what I’ve noticed:
✨ Smoother Skin Texture
The most obvious change is how smooth my skin feels. My pores, especially on my cheeks and nose, look visibly smaller, and overall my complexion looks more refined. Even my makeup is going on more evenly.
💫 Clearer, Calmer Skin
My skin is oily and a bit breakout-prone, but since starting this serum, I’ve had fewer pimples and less congestion. When a spot does show up, it clears faster and leaves less scarring.
💪 Preventive Skincare That Feels Empowering
I’m in my mid-20s, so while I don’t have deep wrinkles yet, I’m a big believer in collagen banking—doing what I can now to protect my skin’s firmness and elasticity long-term. This serum makes me feel like I’m actively supporting my skin’s future health.
Final Verdict
Overall Rating: 9/10
Pros:
- Gentle yet effective retinol concentration
- Combined with bakuchiol for added results, minus the irritation
- Clinically backed improvements in pores and wrinkles
- Hydrating and barrier-supportive ingredients
- Beautiful, functional airless pump packaging
- Lovely texture that absorbs easily
- Beginner- and sensitive-skin friendly
Cons:
- Slight natural retinol smell (but fades quickly)
- Smaller size (20ml), though ideal for keeping ingredients fresh
Conclusion
If you’ve been thinking about adding retinol to your routine but were intimidated by potential irritation—this is the one to try. The Haruharu Wonder Black Rice Night Knight Retinol Serum is a thoughtfully crafted formula that balances power with gentleness.
Whether you’re aiming to refine texture, clear breakouts, minimize pores, or just future-proof your skin, this serum offers a great starting point.
Just remember: start slow, wear SPF every day, and listen to your skin. With consistency and care, retinol can absolutely transform your skin over time—and this one makes the journey smoother and more enjoyable.
