The Skin Diary may not yet be a household name but among skincare enthusiasts it already carries the quiet confidence of a brand that punches above its weight with science driven formulations. Its latest overnight treatment is deliciously literal in name: Night Repair Therapy promises to tuck your skin into bed and have it wake up looking better than it did the evening before.
The brand touts some bold claims: 20x the potency of retinol, boosted collagen and elastin, a fully restored barrier and absolutely no irritation. All wrapped up in research spearheaded by Professor Chris Griffiths OBE and Dr Tamara Griffiths who have spent decades decoding skin biology. It is an enticing pitch, especially if late nights, sun exposure and the occasional skipped SPF have left their mark.
I put Night Repair Therapy through a full two-week test drive, applying it nightly to see if it could live up to its high-tech promise and merit a spot in an already crowded routine.

What Is Night Repair Therapy?
Night Repair Therapy is an overnight treatment, meaning a leave-on product designed to work while you sleep. Overnight formulas tend to be richer and more active than daytime moisturisers because they do not have to contend with UV, pollution or makeup. They take advantage of the skin’s natural repair window when cell turnover peaks and trans-epidermal water loss rises, allowing actives to penetrate more effectively.
This particular treatment sits at the intersection of anti-ageing and barrier support. The Skin Diary positions it as a clinically proven alternative for people who want the wrinkle smoothing benefits of retinol without the dryness and flaking that often come with traditional vitamin A. According to the brand, the blend of peptides, a gentler retinyl ester and antioxidant plant extracts is 20 times more effective than standard retinol at stimulating collagen and elastin. At the same time, a base of fatty acids and humectants aims to replenish the lipid layer so the skin stays calm and hydrated.
In practical terms you apply Night Repair Therapy as the last step of your evening routine, allow it to absorb then let it get on with fortifying the skin against photo damage, fine lines and moisture loss until morning.
Did It Work?
In the name of science I benched my usual overnight cream for a few days, a move that felt very lab-coat of me given the test subject was my own face. Fourteen nights struck me as a decent window to judge performance so I applied two pumps as the final step every evening, no facial oils or sleeping masks allowed to muddy the waters.
Texture wise Night Repair Therapy is a light custard that spreads easily and sinks in within a minute. The first morning my skin felt pleasantly cushioned, not greasy, with a subtle sheen that suggested good overnight hydration. No redness, no tingle, no odd pillow stickiness. Sensitive skins will appreciate that uneventful start.
By day seven I noticed the areas around my mouth and between my brows looked a touch smoother. The effect was more “well rested” than “airbrushed” but it was visible in natural light. My cheeks, prone to winter flakiness, stayed free of dry patches which speaks to the barrier support claim. What I did not see was any change in the two sun spots on my left cheek or the slightly slack jawline that keeps reminding me of gravity.
Heading into the second week the glow plateaued. Skin remained comfortably hydrated and calm yet the promised firmer, springier feel never fully materialised. Fine lines were softened rather than erased and overall tone looked even but not dramatically brighter. On the upside I experienced zero irritation so the gentle label holds up.
After fourteen nights I would score Night Repair Therapy a solid if unspectacular success. It moisturises, soothes and offers a modest smoothing effect but the headline claim of being twenty times more effective than retinol feels ambitious. I will finish the jar because it plays nicely with my skin however I am not racing to make it a permanent resident on my shelf.
Night Repair Therapy’s Main Ingredients Explained
The formula is split into three themed clusters so let’s tackle them in that order. In the Protect phase bilberry extract acts as an antioxidant bodyguard, neutralising free radicals before they nibble away at collagen. Lycopene rich tomato skin offers a second shield by dampening photo-oxidative stress which is science speak for the chain reaction that follows too much UV. A decent 5% niacinamide rounds out the trio and quietly improves barrier strength while keeping pigmentation in check.
Renew is where the heavy lifters sit. Palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7 are the same matrikine pair found in many clinical serums aimed at wrinkle depth so the inclusion here is meaningful. Retinyl palmitate, a gentler ester of vitamin A, encourages cell turnover but with far less sting than traditional retinol. It is worth noting that any vitamin A derivative is classed as a no-go during pregnancy so always clear it with a doctor first.
The Restore complex stitches everything together with a cushion of sunflower, coconut, cocoa, almond and jojoba oils plus multi-weight hyaluronic acid. The good news is this blend mimics the skin’s natural lipids so hydration levels stay buoyant until morning. The caveat: coconut oil and cocoa butter carry a higher comedogenic rating which means they can sit in pores and provoke breakouts in acne-prone skin. If you are very oily or struggle with congestion patch test on the jawline before committing.
All raw materials are plant or lab derived and no animal by-products appear on the INCI list which makes Night Repair Therapy suitable for vegans and vegetarians. Fragrance is mercifully absent so the risk of sensitising essential oils is zero. The formula also skips silicones, parabens and drying alcohols, features that will please ingredient purists.
One last note for the savvy shopper: although the peptides and antioxidants are impressive the jar packaging means air exposure is inevitable. Store it away from bright bathrooms and screw the lid promptly to help those actives stay potent for the full shelf life.
What I Liked/Didn’t Like
After two weeks here is the straightforward rundown of strengths and caveats.
What Works Well:
- Light custard texture sinks in quickly and leaves skin cushioned rather than greasy
- Noticeable overnight hydration with steady barrier support that keeps flakiness at bay
- Peptide pair plus retinyl palmitate deliver gentle line softening without any redness or peeling
- Fragrance free vegan formula makes it a safe pick for sensitive or ethics-minded users
What to Consider:
- Jar packaging exposes actives to air so potency may taper over time
- Coconut and cocoa butter content may clog pores on very oily or acne-prone skin
- Firming and brightening results are modest so expectations should be set accordingly
My Final Thoughts
Night Repair Therapy lands at a solid 7.5/10 for me. It’s a dependable performer – the kind that delivers consistent results without fanfare. If your skin leans sensitive, dehydrated, or you’re wary of harsh retinols, this cream makes a courteous companion. It smooths fine lines, keeps flakes at bay, and does it all without the drama of peeling or purging. However, if you’re chasing rapid pigment fading or dramatic lifting, you might find yourself wanting something stronger.
I’ve tested my share of overnight treatments and gave this one a fair trial: two uninterrupted weeks, no competing serums, no sneaky face oils. The takeaway is simple. Night Repair Therapy is for the cautious optimiser who values comfort and incremental gains. It is not for the thrill seeker chasing prescription-level results overnight. Would I recommend it to a friend? Yes, but with the note that it’s more restorative lullaby than cosmetic mic drop.
Should you fancy window shopping before settling down, a few alternatives I’ve personally drained to the last dollop deserve mention. Deascal’s Nocturnal Revive Cream is an excellent all-rounder, the sort of covers-all-bases formula that behaves on every skin type and does so at a wallet-friendly price. Medik8’s Advanced Night Restore leans into ceramides and antioxidants for those who crave barrier repair with a side of brightening. If plush texture and spa-like scent are your love language, ELEMIS Pro-Collagen Night Cream delivers both while still firming noticeably. For the minimalists, BIOSSANCE Squalane + Ectoin Overnight Rescue offers heavyweight hydration in a featherlight gel that never clogs a pore.
Before you slather: A quick patch test along the jaw for a night or two is always wise – irritation diaries are no fun. Remember, any smoothing or firming benefits will only stick around with consistent use, so keep the jar handy and pair it with daily SPF.
