I started using Dr. Wu Intensive Renewal Serum With Mandelic Acid 18% about eight months ago. I started with the 18% version as I am worried that the 8% one is too mild for my normal to dry skin. My mom uses the 8% version.
About a month before purchasing this serum, my friend and I discussed how our complexion had greatly improved by incorporating acids into our daily skincare routine. She then mentioned how she briefly came across the term “mandelic acid” but did not bother doing much research into it.
Being a naturally nosy person, I thought I should maybe educate myself on this new acid lest I miss out on a star ingredient that could give me flawless skin … wishful thinking, but hey, what is life without hope amirite?

On their website, this father and son company (interestingly known as the ‘Godfather of Cosmetic Medicine’ in Taiwan) claims to allow their customers to “enjoy skincare just like having a doctor perform medical treatments at home.”

Key Ingredients Explained
Mandelic acid
Mandelic acid is derived from bitter almonds and is an alpha hydroxy acid (AHA). It is most suitable for hypersensitive skin types, and being gentler, it would be perfect for those dipping their toe in the AHA/BHA pool for the first time. It targets three main skin concerns: wrinkles / fine lines, hyperpigmentation, discoloration, and acne.
This miracle acid strengthens collagen and sloughs off the outermost layer of the skin, allowing it to reflect light better, thus making the skin look more youthful. It also excels at correcting skin tones, and because it is so gentle, it can be used by those with rosacea.
This serum contains 18% mandelic acid, but do not be put off by this high concentration as it is, in reality, very gentle.
If you want to learn more about the benefits of mandelic acid for the skin, here is Alyssa‘s Guide:
Other ingredients like Beta-Glucan, Centella Asiatica, Panthenol, Calendula Flower Extract, and Allantoin are all soothing ingredients to calm and heal the damage and irritation potentially caused by the chemical exfoliation.
Ingredients not included in Dr. Wu Intensive Renewal Serum With Mandelic Acid 18%: alcohol, fragrance, and essential oil free.
Packaging
The product comes in a brown glass bottle, which protects the contents from excessive light. Labeling is minimalistic, as with most cosmeceutical products, where the product speaks for itself and does not need to rely on fancy-schmancy labeling.
It has a rubber tip, which works well to pick up a good amount of the product with a squeeze. A tiny complaint I have is that the bottle does not close properly. It is just a standard screw cap bottle, but it will pop open again if you apply pressure and try to tighten the cap when closing (I like to ensure all my products have their covers screwed on tightly).
I am not sure if it is my bottle that may be a little defective or if that is the case with all bottles. We shall see when my second bottle arrives. Yes, I love it so much I can see this becoming a staple in my routine.
Smell
It smells faintly of almonds, and each time I use it, it evokes a memory of when I was growing up in Malaysia and how I used to love the hot almond milk tea from a particular street vendor. Not only did it have a comforting smell of almonds, but it also tasted divine. Yum….
After a bit, the smell disappears, so do not worry about those who dislike fragrances in their products.
Texture
Dr. Wu Intensive Renewal Serum With Mandelic Acid 18% is a clear and runny liquid that comes in a dropper form.
I find the serum a bit oilier than what I am used to, maybe because the other serums I use, in comparison, dry up relatively quickly on my skin.
My Skin and My Mom’s Skin After 60 Days
I should have reviewed this six months ago, but I have so many other things to review, and I still have more than half left in the bottle, hence the delay. I was not paid for this review or received it as a gift.
The main ingredient, Mandelic acid, is an excellent alternative to glycolic acid as it has larger molecules and is less irritating to the skin. It doesn’t give me the tingling effect glycolic acid typically does. It is also oil-soluble, so people with oily skin can use this too. It will clear out blackheads due to its oil solubility properties. Mandelic acid works like all other AHAs to target aging-related problems. It can diminish the appearance of fine lines and remove the aged epidermis. Doing so will give you smoother, clearer, younger-looking skin!
The first time I applied this serum to my skin, I wasn’t too fond of it. The serum is a bit oily and has a chemical scent. But, after applying this serum, my skin feels softer and plumper. Maybe it is a combination of the serum and the mini face massage I give myself. It absorbs well into the skin, and here is where I am thankful for the slightly oilier consistency, as my skin does not tighten and dry out while I wait 15 minutes before continuing with the next step. During that waiting period, my skin feels nicely moisturized and hydrated.
The nostalgic smell and the plumper feeling of skin is an excellent tri-weekly skin booster, and my skin thanks me for it. I cannot provide concrete reviews on its anti-aging properties as I do not yet have many wrinkles or fine lines, but I think this serum helps slow aging.
As for blackhead removals and pore cleansing, my nose strips testify that gunk still lurks in my pores. My complexion is brighter regarding brightening properties, and the blemish marks around my chin slowly fade. As with most good things, do not expect instantaneous results because it takes time.
This would be the one if I were to recommend an AHA serum. It is the gentlest and most effective one I have tried. I also love The Ordinary Glycolic Acid toner*, but that one is more like an AHA toner, and TO uses a more potent acid (glycolic), which always gives me a slight tingling effect. Dr. Wu doesn’t have that, so you know it can tackle sensitive skin, too.
Also, my mom had excellent results. Finding a gentle AHA that works so well on my mom’s skin is exciting since she is reaching her 50s.
How to Use Dr. Wu’s Serum?
You may be wondering where something like this fits into your routine.
At night:
- Cleanse;
- I drop about five drops of the serum on my face and give it a good massage for a few minutes. I avoid the lip and eye area.
- Please wait 15 minutes for the product to absorb before continuing with my toner. This will impede the pH or the toner’s ingredients from interfering with this serum’s efficacy.
- Follow up with Vitamin C serum (preferably in the AM, optional);
- Follow up with your first treatment essence (optional);
- Rest of your toner(s) and serum(s);
- Moisturizer
- SPF or sleeping mask.
I use this product thrice a week. You must wear sunscreen daily after using it as it will make your skin more vulnerable to sun damage!

Photos Before and After
When I started using this, I was not in the mood for selfies, so I didn’t keep any before and after pictures. I noticed that it helps remove zits and bumps on my skin. There was also a soft glow on my skin when I started to use this. But it doesn’t help fade my freckles.
My mom, however, got better results. She sent me her pictures almost daily to rave about how this makes her skin a lot brighter and younger, her pore sizes smaller, and her fading dark spots.
I know she is on her 3rd bottle since this has made her a different person altogether. Her skin is now a bit younger, smoother, baby-soft, less dull, and brighter. She suffers from lesser acne and blackhead issues, too! Double thumbs-up from her!
Pros
- a gentle and effective formula
- convenient dropper design
Cons
- pricey (unless you buy it in Taiwan)
- AHA serum is quite a hassle to use
Verdict
This mandelic acid serum is a chemical exfoliant that refined my skin texture. It works like SK-II Facial Treatment Essence* or any other treatment essence but at a much faster rate and is less pricey than those.
I would say I like it.
Will I Repurchase Dr. Wu Intensive Renewal Serum With Mandelic Acid 18%?
Sometimes, I think there are so many excellent skincare products out there, and repurchasing a particular product is so lame when there are so many options left to try, which might be even more impressive. However, this serum suits me so well. I only use it thrice a week and am happily willing to incorporate it into my routine.
