10% Gluconolactone (PHA): Known as gentle giants of the hydroxy acid family, PHA molecules are larger and allow gradual penetration into the skin to dissolve dead skin, revealing a glowy and younger-looking complexion without causing stinging, burning, itching or redness sensations, and UV sensitisation of that experienced with traditional AHAs.

A multi-tasking super ingredient, PHA also acts as a humectant, which means that they attract and retain moisture as they fight glycation, a process that weakens collagen and elastin in the skin. The results? A plump, hydrated and smooth complexion with a reinforced skin barrier primed to keep the signs of ageing at bay.

Kakadu Plum: A superfruit containing an interesting antioxidant, collagen-boosting cocktail of gallic acid, ellagic acid and Vitamin C to boost skin luminosity and radiance. Kakadu Plum is also known as the world’s highest source of Vitamin C, containing 5300 mg of Vitamin C per 100 g compared to just 53 mg of Vitamin C per 100 g of oranges!

Pumpkin Seed Extract: A patented blend of 2 ingredients: a marine spring water naturally rich in trace elements, and an alkaline amino acid extracted from the seeds of Cucurbita pepo that acts to quickly soothe skin inflammation and limit skin reactivity. A 20 women sensitive skin panel evaluated by a dermatologist showed significantly reduction in skin sensitivity of up to 24% within 7 days and up to -42% within 14 days of daily use.

Heard alot of good reviews and decided to try it. I think I've been through at least 2 bottles? Love that doesnt sting my sensitive skin or irritate it. Great for layering with other serums too. Helps my skin achieve smoother and radiant surface in a short time!

Totally Hydrating

I had purchased LUMIWHITE 10% PHA RESURFACING GLOW SERU for the 4th time. For first time, I bought it as I saw the ad. When I used it, it was totally like what the ad described. My skin is combination skin and thus some areas are dry. When i used this product before my moisturizer, it glided so smoothly on my skin. At times when my skin dries due to coffee overdose, this product actually prevents it from dehydration. It is really effectively hydrating (like the skin soaked in readily, without the usual oil serum type) and I also noticed my skin getting whiter with use. Thank you est.lab's team for their dedicated customer service as well!

Smooth and clearer skin

It's my first time trying out a serum with PHA and i have been using it for almost 10 days. My skin is smoother and clearer and I can see a natural glow after about a week. It absorbs really quickly onto my skin and I have been using this daily every day and night.


The packaging is so pretty and refined. I havr combination skin and its not oily at all. It is absorbed very fast into my skin. Used 2 days so far and i could see more clarity on skin surface. Looking forward to using it for a longer period.

Amazing results

I have very dull skin due to long term pigmentation. After I have used this pha serum for maybe about a week or so, the pigmentation lighten up and my face looks more radiant now. Very satisfied with the results.
