Priori LCA fx161 Hydrofill Masque Review
The Verdict
Priori LCA fx161 Hydrofill Masque is a genuinely flexible hydration step — a low 2% lactic acid content, antioxidant vitamins and moisture-binding sericin and algae extract, in a fragrance-free base gentle enough for sensitive skin. It suits anyone whose skin feels tight, dull or dehydrated, whether used as a quick 10-minute treatment or left on overnight. Patch test first if your skin is reactive, and anyone pregnant or breastfeeding should contact our team for advice before use.
Priori LCA fx161 Hydrofill Masque | Hydrating AHA Face Mask | 120ml
£62.50
Priori LCA fx161 Hydrofill Masque is a fragrance-free, creamy hydrating treatment built around a 2% LCA Complex (pH-correct lactic acid) plus vitamins A, C, E and Pro-Vitamin A, with sericin and algae extract for moisture. Priori positions it for all skin types, including sensitive, and it works either as a 10-minute treatment or an overnight mask.
What it is
The Hydrofill Masque is a 120ml rinse-off (or leave-on overnight) treatment mask from Priori's LCA range — the sub-range built around a pH-correct lactic acid complex rather than higher-strength acids. Here the lactic acid sits at a gentle 2%, so it's doing a supporting exfoliating job rather than acting as the headline active. The main focus is hydration: a thick, non-greasy cream-gel texture designed to sit on the skin and lock moisture in, rather than a rinse-and-go clay or sheet mask.

Who it's for — and who should skip it
Priori positions this as suitable across the board: sensitive, dry, normal and oily skin are all listed, with the fragrance-free formulation aimed at making it usable even for reactive skin types. It's a reasonable pick if your skin is feeling tight, dull or dehydrated, if you want a mask that also carries a mild exfoliating element rather than pure occlusion, or if you like the flexibility of a quick treatment on busy days and a longer overnight option when you have time.
It's a lower priority if you're specifically after a strong exfoliating or resurfacing mask — the 2% lactic acid here is gentle by design, so anyone chasing a stronger AHA effect is better served by a higher-percentage LCA-range product. Because it does contain an AHA, get professional advice first if you have rosacea, eczema or another active skin condition, and don't use it immediately after a chemical peel, laser treatment or microdermabrasion.
How to use it
- Apply a generous layer to cleansed skin, avoiding the eye area
- For a quick treatment, leave for around 10 minutes, then rinse or tissue off
- For an overnight option, apply as the last step before bed and leave on; follow with your usual morning routine
- Use 1–3 times a week depending on how your skin responds, and always follow with a broad-spectrum SPF the next morning, since AHAs increase sun sensitivity
Pregnancy and breastfeeding
If you're pregnant or breastfeeding, please contact our team for advice before use.
Key ingredients
The 2% LCA Complex (lactic acid) is formulated at Priori's signature pH-correct level, meant to support gentle skin renewal without the tightness or flaking a stronger AHA can bring. Alongside it sit Vitamin C, Vitamin E, Vitamin A and Pro-Vitamin A — an antioxidant line-up included to help support the skin's defence against everyday environmental stress, alongside the mask's core hydrating job.
Sericin, a silk-derived protein, and algae extract are the two ingredients doing most of the moisture-binding work here — both are humectant-type ingredients used to help draw and hold water in the skin's surface layers, which is what gives the mask its plumping, smoothing finish once removed.
Priori doesn't publish independent clinical trial data for this specific formulation, so we've described what each ingredient is included to do rather than repeating unverified efficacy claims from the brand.
Where it fits in a Priori routine
The Hydrofill Masque pairs naturally with other products in Priori's LCA range built for comfort over intensity. If your skin needs barrier support alongside hydration, LCA fx140 Barrier Restore Complexe is a ceramide-led moisturiser aimed at sensitive or reactive skin, and works well as a daily step either side of a weekly masque session. For a gentle daily cleanse that won't undo the mask's work, see our review of the LCA fx110 Gentle Cleanser.

FAQs
Is Priori Hydrofill Masque good for sensitive skin?

Can I leave Priori Hydrofill Masque on overnight?
Yes — Priori designs it for either a quick 10-minute treatment or use as an overnight sleep masque, so you can choose whichever suits your routine that day.
How often should I use the Hydrofill Masque?
Around 1–3 times a week is a reasonable starting point, adjusting up or down depending on how your skin responds and what else is in your routine.
