IN PARTNERSHIP WITH THE SKIN DIARY
A deep dive into the clinically proven two-step system from The Skin Diary …
Does your skin need a new year reset? Then forget passing trends or fads and look to a simple Irish line that delivers scientifically proven results. The Skin Diary is an expert-led luxury brand co-founded by consultant dermatologist Dr Clare Kiely from Co Mayo. It’s firmly centred on an evidence-based, real-world approach to skincare.
The Skin Diary has been developed by Dr Kiely and a team that includes world-renowned skin ageing expert Professor Chris Griffiths OBE, a pioneer in the use of topical retinoids. Through dermatological expertise and rigorous scientific testing, the team has developed two key products that protect, repair and restore the skin every day. Meet The Skin Diary’s Age Defence Moisturising Day Cream (€110) and multi-award-winning Night Repair Therapy Cream (€160).
Some of Ireland’s foremost skin experts recommend The Skin Diary. Dr Rosemary Coleman consultant dermatologist at Blackrock Clinic, Co Dublin, is hugely impressed with the Night Repair cream, calling it her favourite product of 2025. “I don’t think it has any competition for containing the best and most complete menu of active ingredients in one night cream,” she says.
Great skin doesn’t follow trends, it follows data. And what stands out with The Skin Diary is the level of scientific testing. Rather than rely solely on consumer studies, the team rigorously tests formulas to a gold standard, to ensure lasting, superior results – cellular change beneath the surface of the skin.
The Skin Diary’s Two-Step System To Great Skin
STEP 1: The Skin Diary’s groundbreaking Age Defence Moisturising Day Cream (€110) shields the skin from daily exposure. It’s designed to shield the skin from daily aggressors, countering UV-induced cellular ageing. The formula combines extensively researched ingredients, including encapsulated broad-spectrum SPF50, DNA repair enzymes (an exciting innovation that repairs UV damage as it occurs) and antioxidants to restore youthful, radiant skin. Age Defence reduces cellular senescence, inflammation and collagen breakdown. Age Defence Moisturising Day Cream is an “everything” day cream, offering everything from robust protection to lasting hydration.
WHY WE LOVE IT: The velvety cream provides lightweight all-day hydration that works beautifully under make-up, creating a smooth finish. When it comes to sun protection, what’s vital is that the SPF is pleasant to use and easy to apply. Most visible ageing stems from sun exposure, and this formula is your first point of defence.
STEP 2: Ten years in the making, multi-award winning Night Repair Therapy Cream (€160), a gentle yet potent blend of retinyl ester, peptides, bilberry and humectants, is proven to reverse signs of ageing, repairing cells beneath the skin’s surface. In human-skin biopsies and placebo-controlled studies, it was found to double collagen and fibrillin (the skin’s elastic scaffolding), showing effects to be 20 times more effective than retinol, without irritation. It significantly reduces wrinkles within 12 weeks, visibly reversing the signs of structural ageing. Skin feels renewed, comforted and deeply restored by morning, so you wake up with bouncier, more radiant skin. .
WHY WE LOVE IT: This pillowy cream feels like a cashmere comfort blanket on your skin at night. Luxurious yet non-sticky, it’s a treat for your skin, and is well tolerated even for those with sensitive skin, so it’s an excellent alternative to a retinoid.
Together, The Skin Diary duo offers advanced protection by day and deep repair by night in a simple routine that suits all skin types. The system is built on the dermatological evidence that protecting skin during the day, and restoring cellular health at night, are vital when it comes to optimal ageing, supporting the skin’s natural renewal processes while strengthening its barrier. By stripping away unnecessary steps, the brand delivers effective skincare that supports long-term skin health through a simple, considered routine.
