A Closer Look at Its Key Ingredient, Mandelic Acid
At the heart of DR.WU’s Intensive Renewal Serum is mandelic acid, a key ingredient that redefines gentle exfoliation. Mandelic acid offers a milder approach while still providing effective results, unlike more abrasive exfoliants such as glycolic and salicylic acids.

It removes dead skin cells, unclogs pores, and promotes a brighter, smoother complexion. Mandelic acid is particularly effective in addressing a range of skin concerns, including acne, uneven skin tone, and dullness, all without causing irritation.

With a pH formula of 3.5 to 3.8, DR.WU Mandelik Intensive Renewal Serum offers a mild yet effective solution for optimal skin rejuvenation.
The combination of ingredients in DR.WU’s Intensive Renewal Serum does more than just exfoliate. “B-Polyglucosome can help deliver mandelic acid and hyaluronic acid more effectively into the skin, enhancing their overall benefits.
While mandelic acid can sometimes cause dryness or irritation, hyaluronic acid helps to counteract these effects by providing moisture and soothing the skin,” Dr Ang shared.

DR.WU Mandelik Intensive Renewal Serum Expert Review
To provide insight into the effectiveness of DR.WU Mandelik Intensive Renewal Serum, we turn to Dr Ang’s expertise.
As someone with a combination-oily skin type that’s prone to acne, Dr Ang’s primary skin concerns include uneven skin tone, enlarged pores, and occasional blemishes.
She has explored a range of skincare solutions, from moisturisers and hydrating serums to topical treatments and professional procedures like chemical peels and microneedling.
While many renewal serums have addressed her concerns, none have delivered long-lasting or comprehensive results. She noted that although professional treatments such as lasers and chemical peels are effective, they demand regular maintenance and can be costly.
First Impressions of DR.WU Mandelik Intensive Renewal Serum

Upon receiving DR.WU Intensive Renewal Serum with 18% Mandelic Acid, she was impressed by its lightweight, gel-like texture and quick absorption.
“My first impression of the DR.WU Mandelik Intensive Renewal Serum was quite positive, especially considering its reputation for being effective yet gentle.
The serum has a lightweight, almost gel-like consistency, making it easy to apply and layer with other products. It absorbs quickly without leaving a sticky residue, which is a plus for those with oily or combination skin.”
She added that “it seemed like a well-formulated, user-friendly product suitable for regular use, particularly for those looking to gently exfoliate their skin without the harshness of stronger acids.”
Is Mandelic Acid a Better Option Compared to Other Chemical Exfoliants?
“Mandelic acid is known for being a gentler AHA compared to others like glycolic acid and salicylic acid as it has a higher molecular weight structure and penetrates through the deeper part of skin gradually without irritating the epidermis (i.e. top layer of skin),” Dr Ang highlighted.
She continued sharing that the mandelic acid “made the serum feel approachable, especially for those with sensitive skin or first-time acid users. The promise of exfoliation without significant irritation was appealing.”
Dr Ang found the serum particularly beneficial in her routine, noting, “After using the serum for a week, I noticed a visible reduction in blackheads and breakouts, and my pores appeared more refined. It’s rare to find an exfoliant that’s effective but also hydrating.”
The Results

After two weeks of consistent use, Dr. Ang noticed significant improvements in her skin.
“My pores appear smaller, my skin felt smoother, and there was a visible brightness that hadn’t been there before. I didn’t experience any irritation or breakouts during the trial period, which is a common concern with exfoliating serums,” she praises.
With continued use, Dr Ang’s skin looked noticeably clearer and more radiant. “the serum delivered on its promise of minimising pores and brightening my complexion. I especially appreciated how lightweight it felt, even when layered with other products.”
“But what makes this serum particularly interesting is its potential to deliver results in such a short timeframe. It’s possible to see visible improvement, especially with acne and pore size, within seven days of consistent use.
The serum’s 18% mandelic acid concentration is potent enough to make a difference quickly without overwhelming sensitive skin,” Dr Ang explained.

For those dealing with acne, enlarged pores, or dull skin, the DR.WU Mandelik Intensive Renewal Serum offers a gentle yet effective solution. Dr Ang believes that its formulation is particularly suited for individuals with sensitive skin or those new to chemical exfoliation.
“The combination of mandelic acid with hydrating ingredients like hyaluronic acid makes this serum stand out. It exfoliates without stripping the skin, leaving it smoother and brighter without irritation,” she says.
