Best Face Masks Under £20
A face mask is a concentrated treatment held against the skin long enough to do something a rinse-off product cannot. Which type is right depends entirely on the outcome you want: clay and charcoal masks absorb oil and suit congested skin; sheet and gel masks flood the skin with humectants and suit dehydration; exfoliating masks use acids or enzymes to work on texture; overnight masks are essentially occlusive moisturisers left to work while you sleep. The mistake that recurs across this category is treating masks as an intensity dial — using a strong clay mask on dry skin because it feels like it must be doing more. The picks below are masks available on Amazon UK, ranked on customer rating weighted by review volume.

What to look for
Clay masks should not be left to crack
Once a clay mask dries fully it starts pulling moisture from the skin rather than oil from the pores. Rinse while it is still slightly tacky — the fully cracked look is a sign it has gone too far.
Sheet masks are about the serum, not the sheet
The fabric is a delivery mechanism for the essence it is soaked in. Read the ingredient list as you would for a serum, because that is effectively what you are buying.
Do not stack exfoliation
An acid mask on the same evening as an acid toner or a retinol serum is a common route to irritation. Masks are a treatment step and should replace other actives that day, not join them.
Multi-masking is reasonable, not a gimmick
Applying clay to an oily T-zone and something hydrating on drier cheeks reflects how combination skin actually behaves. It costs nothing beyond a little time.
Frequency is lower than the packaging suggests
Once or twice a week suits most skin for treatment masks. Hydrating masks can be used more freely, but a clay or acid mask several times a week will eventually show as sensitivity.
Frequently asked questions
- How often should I use a face mask?
- Once or twice a week for clay or exfoliating masks. Hydrating sheet or gel masks can be used more often, since they add rather than remove.
- When in a routine does a mask go?
- After cleansing, before the rest of the routine. Rinse-off masks are followed by toner, serum and moisturiser as normal; overnight masks go last, as the final sealing step.
- Are sheet masks worth it?
- They deliver a large dose of hydration in fifteen minutes, which is genuinely useful before an event or after travel. As a daily habit they are an expensive and wasteful way to buy essence.
- Should a clay mask dry completely?
- No. Rinse it while it is still slightly tacky. Letting it dry fully draws water out of the skin, which is why skin often feels tight after a mask that was left too long.
