How Often Should You Get a Facial? What the Skin Measurements Actually Say

How often should you get a facial? The answer most spas give is once a month, and the reason they give is that skin renews itself every 28 days. There are two problems with that. The scientists who measured how long skin takes to renew got answers from about 20 days to 48, depending on which layer they measured, how, and in whom. And nobody has tested whether a facial every four weeks does anything a facial every eight, or a facial now and then, does not. The honest answer is shorter: a gentle mask facial can be repeated within the weekly limits dermatologists give for face masks, the exfoliating part has a stricter limit, and on a holiday one is enough. We are Nghê Prana, a riverside hotel and spa on the Thu Bồn at Cẩm Nam in Hội An; our facials are three plain masks with a face massage, and this page is written so that you could decide not to book a second one.

How often should you get a facial: the short answer

AAD is the American Academy of Dermatology, whose patient pages were read on 17 October 2026; Vinmec is the Vietnamese hospital group, whose skin-care pages are dated July 2024; Werner is A Massage Therapist's Guide to Pathology, 5th edition, the standard textbook on when not to massage. The skin-renewal studies are below, with their numbers. "Our reading" means exactly that: a judgement from the sources, not a finding.

Where "every four weeks" comes from

The 28-day figure has a respectable ancestor. In 1965 the dermatologists Weinstein and Van Scott tracked labelled cells through the living layers of the skin and found they took about 13 days to cross them. Added to an earlier estimate of 13 to 14 days for the dead outer layer, the stratum corneum, that gave "26 to 27 days" for the whole epidermis (Journal of Investigative Dermatology, vol. 45, as recorded by Harvard's BioNumbers database; the paper has no abstract online and we have not read it in full). Round it up and you have a month. That this is where the spa rule comes from is our inference; nobody we found says so in print.

The measurements since then have mostly come out longer. Weinstein's own group, repeating the work with better methods in 1984, put "the mean epidermal turnover time of the entire tissue" at 39 days. Ten years later Iizuka recalculated the same data and got 47 to 48 days. And age matters: Grove and Kligman, timing how long a fluorescent dye took to wear off the skin's surface, found the outer layer renewed in about 20 days in young adults and took more than ten days longer in older adults, with the slowing becoming marked after fifty.

None of these papers is about facials. They measure how long skin takes to replace itself, which is a fact about skin, not a prescription for a spa. A facial does not reset that clock, and nothing in the literature we searched links the two. We searched the medical literature on 17 October 2026 for any trial of how often to have a facial and found none.

What dermatologists say about routine facials

The clearest statement of the doubt is a 2009 New York Times piece by Catherine Saint Louis, "An Expression of Doubt About Facials": "Aestheticians and spas have long promoted such routine facials as required maintenance for radiant skin. But dermatologists don't necessarily agree." Leslie Baumann, a dermatology professor at the University of Miami, called a facial "a great cost to cut" because "it's not doing anything preventative or anything long term for your skin". Amy Derick suggested that "massaging of the skin alone can cause temporary swelling", which may be the lifted look people notice afterwards. And Jeffrey Dover said something aimed squarely at places like ours: "If you drop into a hotel, they do a similar thing to everybody. It's a recipe." That is a fair criticism, and the answer to it is to tell us about your skin when you book; we have three masks for different skin, not one.

The American Academy of Dermatology's page on face masks (updated March 2026) is kinder but makes the same point: masks "can help you address some skin concerns", but "a facial mask is not a replacement for your skin care routine", and if you "apply it too often, your skin may end up feeling worse". Read together, the sources describe a facial as a pleasant hour and a glow that lasts a day or two, not as maintenance. The maintenance is the daily routine and the sunscreen.

The part with a limit: the scrub

Exfoliation is the one part of a facial with a frequency rule, and even that rule is a sliding scale. The AAD's page on exfoliating safely (updated February 2026) says "How often you exfoliate depends on your skin type and exfoliation method", and "Generally, the more aggressive the exfoliation, the less often it needs to be done", warning that over-exfoliating leaves skin "red and irritated". It adds two cautions that matter for a holiday: avoid strong scrubs if you have a darker skin tone or dark marks left by spots, burns or bites, because harsh exfoliation can increase pigmentation; and "Never exfoliate if you have open cuts or wounds or if your skin is sunburned." Vinmec's Vietnamese page on how often to exfoliate the face gives numbers: "Thông thường, tẩy da chết khoảng 1-2 lần/tuần, tuy nhiên tần suất này còn tùy thuộc vào loại da", usually about once or twice a week depending on skin type, and it warns that physical scrubs can abrade the skin if used several times a week.

On our menu the scrub is the sea salt and fresh milk scrub mask: fine salt, which is mechanical exfoliation by friction, as our facial page says plainly. One in a week sits inside both the AAD's caution and Vinmec's numbers. If you scrub at home, or you have had a body scrub with us the same week, choose one of the other two masks instead. If you take isotretinoin, the AAD's isotretinoin page lists sugar, coffee grounds and exfoliating beads among exfoliants that "can weaken and irritate your skin"; skip the scrub entirely and tell us when you book.

Masks: the part you can repeat

Vinmec's page on how often to use a face mask (July 2024) reports dermatologists' guidance of one to three times a week, depending on what the mask is for. Our other two masks are the gentle end of that: oat, yogurt and honey for dry or reactive skin, and green tea with yogurt for skin that has been in the sun. The AAD lists colloidal oatmeal among ingredients that "can soothe irritated skin"; ours is a kitchen oat mask, not a certified colloidal oatmeal, and our facial page explains the difference. Either mask twice in a week is well within the guidance. The AAD's rule for any mask is the one to remember on the day: wash it off immediately if you feel itching, burning or stinging. Tell the therapist and it comes off.

Facials and the Hội An sun

A holiday in Hội An is mostly sun, and that changes the timing more than the frequency. A burned face should not be scrubbed or massaged: the AAD says never to exfoliate sunburned skin, and Werner allows massage over a burn only when it is "very mild sunburn" (p. 53). Our page on massage after too much sun has the rest. There is also the question of sun after a facial. The United States Food and Drug Administration's page on alpha hydroxy acids reports that after four weeks of using an AHA cream, volunteers' sensitivity to sunburn rose by 18 percent, reversibly, and it advises sunscreen while using such products and for a week afterwards. Yogurt contains lactic acid, which is an alpha hydroxy acid, but we do not know how much is in our masks and they are rinsed off after about twenty minutes, so we do not apply that figure to them. We would still put on sunscreen after any facial before going out, and we suggest booking yours for late afternoon, after the beach rather than before it.

How many facials on a trip

Our answer for a stay of a week or two is one, and two at most on a long stay if both are the gentle masks. A second scrub in the same week adds friction to skin that is already dealing with sun, salt water and air conditioning. Vietnamese guidance points the same way when it is honest about the evidence: Hello Bacsi's page on spa facials, medically reviewed by Dr Nguyễn Thường Hanh, opens with "Không có một khoảng thời gian cụ thể nào cho việc đi spa chăm sóc da mặt", there is no specific interval for a spa facial; it then suggests once or twice a month "để cải thiện sức sống cho làn da", to improve the skin's vitality, without citing anything for it. For massage the books are more generous, and our how often to get a massage page explains why a massage every day of a holiday is fine where a facial every day is not.

Our three facials, and what each costs

Prices are per person, read from our live spa menu on 17 October 2026; at the 26,000₫ rate we use across the site, 450,000₫ is about US$17 and 600,000₫ about US$23. A facial is also part of four packages: Package 1 Full Recovery at 1,350,000₫ (a 45-minute facial scrub and massage with a mud mask), Package 2 Full Body Cleanse at 1,500,000₫ (a facial scrub, mask and facial steamer), Package 4 To Looking Your Best at 1,440,000₫ (a 60-minute facial massage with mask) and the Nghê Special at 1,890,000₫ (a 60-minute facial). The spa packages page does the arithmetic against booking each part separately, and the facial page explains what is in each mask. Nothing on our menu is a peel, a machine facial or an extraction, and there is no dermatologist on the premises.

What nobody has measured

No trial has compared facial frequencies, and none of the skin-renewal studies was designed to answer the question. The renewal figures themselves come from small groups measured with methods from the 1960s to the 1990s, and they disagree with each other by a factor of more than two. We read the 1965 figure through a database entry rather than the paper. The New York Times piece reports dermatologists' views, not data. And the Vietnamese weekly numbers for masks and exfoliation are guidance for home use, not results of trials. Everything else on this page is our reading of those sources, and we are a hotel spa, not a clinic: if you have a skin condition, your dermatologist's advice comes first.
