([Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/28963772/))
- Nanofibrillar cellulose dressing provides efficient wound healing comparable to polylactide-based copolymer dressings at skin graft donor sites in 24 patients, with significant improvements in observer scar thickness and vascularity and skin elasticity. ([Advances in Wound Care, 2020](https://pubmed.ncbi.nlm.nih.gov/32117583/))
- Topical cream loaded with 2% Ananas comosus extract significantly improved epidermal hydration up to 56.74% and reduced transepidermal water loss up to -73.19% compared to baseline in 11 healthy human volunteers over 12 weeks, outperforming the placebo control. ([Acta Poloniae Pharmaceutica, 2016](https://pubmed.ncbi.nlm.nih.gov/27180442/))
- Oral bromelain slightly reduced pain compared to controls (mean difference -0.27) and topical bromelain reduced time to complete debridement by 6.89 days, with no major health risks reported. ([Nutrition and Health, 2023](https://pubmed.ncbi.nlm.nih.gov/37157782/))
- An upcycled pineapple leaf fibre crosspolymer forms a physical barrier that protects against environmental aggressors while providing antioxidant, anti-inflammatory, antipollution, UV protection, hydration, and hair benefits. ([International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/41524117/))
- A coaxial electrospun core-shell nanofiber scaffold delivering bromelain and salvianolic acid B demonstrated sustained drug release, in vitro endothelial cell migration, increased capillary formation in an in ovo assay, and in vivo efficacy for skin regeneration and wound healing. ([Biomedical Materials, 2017](https://pubmed.ncbi.nlm.nih.gov/28580904/))
- Bacterial cellulose membranes with and without glycerin showed good skin compatibility and no barrier disruption in human subjects compared to a negative control, with glycerin-containing membranes additionally providing a statistically significant skin moisturizing effect (p=0.044). ([European Journal of Pharmaceutics and Biopharmaceutics, 2014](https://pubmed.ncbi.nlm.nih.gov/23973717/))
- AgNP-BC exhibited over 99% reduction in Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa with no cytotoxicity, allowing epidermal cell attachment and growth compared to unmodified bacterial cellulose. ([Carbohydrate Polymers, 2014](https://pubmed.ncbi.nlm.nih.gov/24507345/))
- Cellulose acetate and soy protein hydrolysate nanofibrous dressings promote fibroblast proliferation in vitro and accelerate wound healing with reduced scar formation in vivo. ([Advanced Healthcare Materials, 2018](https://pubmed.ncbi.nlm.nih.gov/29359866/))
- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

## What reviewers say

Based on a very large amount of data, this product is highly praised for its gentle, acid-free enzymatic exfoliation that effectively removes dead skin cells without causing irritation, making it ideal for sensitive, dry, and combination skin. Users consistently report that it leaves their complexion feeling baby-soft, smooth, and radiant, while helping to unclog pores and improve overall skin texture. Some users question the efficacy of the visible 'rolling' effect, suggesting it may be due to the cellulose ingredient rather than actual dead skin removal.

## 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.
