A gentle exfoliating serum powered by 10% PHA (polyhydroxy acid) to smooth rough texture, refine pores and brighten dull skin. Formulated with sensitive skin in mind, it helps improve uneven skin tone, reduce the appearance of pigmentation and leave skin looking brighter and more even, while remaining gentle on sensitive skin.

Formulated with 10% gluconolactone (a high-performing water-soluble PHA) and antioxidant-rich Kakadu Plum, this lightweight formula gently lifts away dead skin cells to reveal smoother, clearer and more radiant-looking skin. Unlike traditional exfoliating acids, it also helps attract and retain moisture, leaving skin soft, hydrated and comfortable after every use.

Known as the super acid for sensitive skin, PHA has a larger molecular size than AHAs, allowing it to exfoliate more gradually while delivering comparable improvements in texture and radiance. It's an ideal alternative for anyone who finds traditional exfoliating acids too harsh.

Clinical studies show that daily use of 10% PHA for 6 weeks helps improve skin clarity while reducing the appearance of pigmentation, roughness and enlarged pores. After 12 weeks, skin texture, tone and firmness improved by up to 2×.

Good for: All skin types, especially dull skin, uneven skin tone, rough texture, enlarged pores, hyperpigmentation and sensitive skin.

Note: Best used on its own. Please avoid layering with other serums that contain Vitamin C, Retinol, AHAs, BHAs, or other exfoliating acids.

For best results, pair with LumiGlow TXA Brightening Cream, powered by Tranexamic Acid to even out skin tone, lighten the appearance of hyperpigmentation and enhance radiance.

Size: 30ml

 


  • Gentle Exfoliation Smooths rough skin texture, refines pores, and boosts natural skin renewal without irritating sensitive skin.

  • Brightens and Improves Skin Clarity Boosts radiance while visibly fading dark spots, post-acne marks, and uneven pigmentation for a clearer, more luminous complexion.

  • Hydrates & Strengthens Attracts and locks in moisture while strengthening the skin barrier to keep skin soft, plump, and resilient.

  • Refines & Smooths Improves overall skin smoothness and minimises the look of pores for visibly softer, clearer skin.

  • Antioxidant Protection Kakadu Plum (rich in Vitamin C) helps defend against environmental stressors and supports long-term skin health.

  • 10% Gluconolactone (PHA): A gentle, sensitive skin-friendly exfoliant with a larger molecular size that absorbs gradually, making it less likely to cause irritation. It smooths rough texture, refines pores, and boosts skin radiance, without the stinging, redness, or photosensitivity often linked to traditional AHAs. It also acts as a humectant to lock in moisture and delivers antioxidant protection to help prevent collagen and elastin breakdown, supporting firmer, healthier skin.

    Clinical studies show that daily use of 10% PHA for 6 weeks significantly improves skin clarity, pigmentation, roughness, pore size, and fine lines, with up to 2x improvement in texture, tone, and firmness after 12 weeks.

  • Kakadu Plum: A powerhouse superfruit rich in Vitamin C, gallic acid, and ellagic acid, it delivers a potent antioxidant boost to help brighten skin and restore radiance. Recognised as the world’s most concentrated natural source of Vitamin C (up to 100x more than oranges), it helps even skin tone, fade dark spots, and defend against environmental stress.

  • Pumpkin Seed Extract: Rich in fatty acids, vitamins, and minerals, it soothes irritation, calms inflammation, and strengthens the skin barrier, helping reduce sensitivity and restore healthy, balanced skin.

    In a dermatologist-evaluated study on women with sensitive skin, daily use reduced skin sensitivity by up to 24% within 7 days and up to 42% within 14 days.

FAQ:
1. Is LumiWhite 10% PHA Resurfacing Glow Serum suitable for sensitive skin?
It is suitable for all skin types, including sensitive, reactive, or compromised skin. Its gentle PHA formulation is designed to exfoliate effectively without irritation.

2. How is PHA different from AHA or BHA?
PHA (Polyhydroxy Acid) has a larger molecular size than AHAs and BHAs, which means it works more gradually on the skin. This makes it safe for sensitive skin, as it provides exfoliation with minimal risk of stinging, redness, or irritation.

3. How is this different from LumiWhite Exfoliating Scrub?
The LumiWhite Exfoliating Scrub uses physical exfoliation with jojoba beads to manually buff away dead skin cells on the surface for instantly smoother skin, while the 10% PHA Resurfacing Glow Serum provides chemical exfoliation, gently dissolving the bonds between dead skin cells to promote cell turnover and reveal fresher, brighter skin over time.

For best results, we recommend using the serum daily for ongoing maintenance and incorporating the scrub 1–2 times a week for an extra boost of smoothness and radiance.

4. Can I use this serum with other active ingredients?
We recommend avoiding layering with other strong actives such as AHAs, BHAs, retinoids, or high-dose Vitamin C in the same routine to prevent over-exfoliation. Always patch-test when introducing new products.

5. How often should I use this serum?
We recommend starting 2–3 times per week to build tolerance, then increasing to daily use if your skin is comfortable.  Although PHAs are much less likely to cause photosensitivity compared to AHAs and BHAs, we still recommend applying sunscreen daily to protect your skin and maintain results.

6. Is this serum safe to use during pregnancy or breastfeeding?
Yes, it is safe for use during pregnancy and breastfeeding. 

7. Which cream works best with LumiWhite 10% PHA Resurfacing Glow Serum?
Pair with LumiGlow TXA Brightening Cream to smooth texture, fade dark spots, and boost overall radiance.

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.

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.
