This Serum is designed to target dullness, uneven texture, and early signs of aging. It blends 10% pure vitamin C for brightening with 8% lactic acid and 2% citric acid for gentle exfoliation, plus retinyl propionate for longterm skin renewal. Hyaluronic acid boosts hydration, while natural antioxidants like white thyme oil and licorice root extract help calm and protect the skin. The formula is fragrance-free and avoids harsh additives like parabens and sulfates.
I’ve tried my fair share of “miracle” serums that promise the world and barely deliver, so I didn’t expect much when I picked up Dr. Perry’s NightThyme Serum. But this one caught my attention because it was developed by a plastic surgeon and backed by actual research (not flashy marketing). After using it consistently at night for a few weeks, I can say it’s one of the few that lives up to its claims without feeling gimmicky.
What’s Inside and Why It Matters
The formula is pretty straightforward: 10% vitamin C (L-ascorbic acid) for brightening and smoothing, 8% lactic acid plus 2% citric acid for gentle exfoliation, and a dose of retinyl propionate (a milder vitamin A derivative) for long term skin renewal. Add hyaluronic acid for hydration and a few natural antioxidants like white thyme oil and licorice root extract, and you’ve got a serum that checks most boxes without overcomplicating things.

It’s fragrance free, no parabens, sulfates, or dyes; which my skin appreciates. I have mildly sensitive skin, and I didn’t experience any redness or burning, just a light tingle that disappeared within minutes.
How It Actually Performs
After about two weeks, my skin looked noticeably brighter and felt smoother. The texture of the serum is lightweight and sinks in fast; no sticky residue or greasy feel. Over time, I saw some fading of dark spots and a slight softening of fine lines around my eyes and mouth. It’s definitely not an overnight transformation, but the progress feels real and steady.
The application is simple: one dropper on clean, dry skin before bed. I learned quickly to let it absorb fully before hitting the pillow; otherwise, you might leave a faint stain. The bottle lasts roughly six months if you’re using it nightly.
How It Stacks Up
Compared to other vitamin C serums I’ve used (like Eva Naturals and SkinCeuticals), NightThyme feels more balanced. It doesn’t just target brightness; it also smooths texture and hydrates. Some brands try to do too much by throwing every trendy ingredient into the mix. This one sticks to proven stuff, which I actually prefer.
The only catch? It’s about $80 per ounce. Pricey, yes, but considering it replaces the need for a separate exfoliant or retinol product, it’s not outrageous if you value simplicity and results.
What I Liked
- Created by a plastic surgeon with real clinical background
- Transparent ingredients with proven science behind them
- Gentle but effective exfoliation
- Fragrance free and great for sensitive skin
- Feels light and absorbs fast
What Could Be Better
- It’s expensive compared to other vitamin C options
- You have to stick with it for a while to see the best results
- Very sensitive skin might tingle at first
- You can’t just toss or shake the bottle carelessly it’ll make a mess
Who It’s Best For
If you want a simple, science driven serum that covers brightening, hydration, and anti aging without layering multiple products, NightThyme fits the bill. It’s ideal for people who prefer clean formulas and steady improvements over “instant” results.
If you’re on a tight budget or want dramatic changes in a week, this might not be your pick. And since it contains exfoliating acids, it’s better suited for nighttime use only.
Final Thoughts
Dr. Perry’s NightThyme Serum feels like something developed by someone who actually understands skin not just someone trying to sell skincare. It’s not cheap, but it’s honest, thoughtfully made, and it works over time. For me, it’s one of the few products that genuinely earns a spot in my nightly routine.
