([Clinical, Cosmetic and Investigational Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30858720/))
- Combining 10% gluconolactone chemical peeling with oxybrasion or microneedle mesotherapy increased skin hydration and decreased sebum, pH, and TEWL in twenty-one Caucasian women, with no significant differences between the two methods. ([Skin Research and Technology, 2023](https://pubmed.ncbi.nlm.nih.gov/37357656/))
- Lactobionic acid produced better skin performance with a lack of skin irritation and barrier impairment compared to glycolic acid in 77 healthy volunteers. ([Journal of Cosmetic Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20367666/))
- Daily treatment with a facial serum containing multiple acids reduced post-inflammatory hyperchromia lesion grade and number by 29.4% at 56 days, and decreased skin oiliness by 30.7% at 7 days in Brazilian patients with acne vulgaris. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))

([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))

([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))

## What reviewers say

Users with hyperpigmentation and dullness frequently praise this cleanser for its ability to gently exfoliate and smooth skin texture without stripping moisture.

## How to apply

- Use this exfoliant PM once a week to start, and gradually increase if your combination skin tolerates it well. Always apply SPF the next morning to protect your clear skin.
- Apply the exfoliant after cleansing and toning, but right before your moisturizer step. This ensures the treatment targets blemishes effectively.
- Gently press 2-3 drops of the exfoliant into your skin without rubbing. Let it absorb for a minute before moving to the next step.
- Apply the exfoliant on clean, dry skin to help control breakouts safely. Since your skin is not sensitive, this dry application method ensures good product absorption.
- Avoid the sensitive eye area and do a patch test before your first use. Do not mix this exfoliant with other strong acids in the same routine.
