Timeline’s winter skin care routine guide
Winter climate can be harsh on the skin. Read on to learn how to keep the skin protected and healthy during the winter season.
What to know
Skin needs to change with the season. Winter climate can be harsh and dry on the skin; skin care requires a focus on protection and hydration.
Winter weather challenges, including low humidity, strong winds, and reduced sunlight, can lead to dry and damaged skin and accelerate skin aging.
Timeline's Skin Health products contain Mitopure®, a powerful compound proven to rejuvenate cells and improve skin resilience.
Skin care is all about identifying what your skin needs, and when it needs it. These needs vary from season to season. While summer skin care calls for more sun protection and rejuvenation, winter skin care requires more hydration. Crafting a seasonal skin care routine can improve overall skin health and appearance. So, let’s take a closer look at skin concerns in winter, and some winter skin care tips to address those concerns!
Winter Skin Challenges
Winter skin challenges and how they impact skin health
You may have noticed your skin appearing dryer and more irritated in the winter months. Weather changes in the winter can strip your skin of important oils and hydrating mechanisms, influencing skin appearance and health. Here are some external factors that dry out the skin in the winter.
Cold air carries less water than warm air. This is why the air is generally dryer in the winter, leading to rough and dry skin (i.e., xerosis). This can lead to an undesirable skin appearance and wrinkling.
Low humidity can also accelerate skin aging and damage skin health. Studies demonstrate that air with low humidity weakens the skin barrier: the outermost layer of skin. The skin barrier is critical to overall skin resilience, health, and longevity. Resilient skin keeps allergens, infections, and irritants out of the body while locking moisture into the skin. Low humidity weakens the skin barrier, leaving the body less protected and skin dehydrated.
Research suggests that strong, cold winds can strip your skin of moisture by damaging the skin barrier. Harsh winds can also stretch out the weakened skin, worsening wrinkles and fine lines.  Excessive skin dryness and damage to the skin barrier can eventually lead to pruritus or eczema.
Although UV-induced damage is a primary accelerator of skin aging, it also stimulates the production of Vitamin D. When exposed to the sun, the epidermis converts a cholesterol derivative into Vitamin D. Research demonstrates that Vitamin D promotes longevity and reduces sun sensitivity in the skin due to its critical role in sustaining mitochondrial health.
Mitochondria and Vitamin D:
Almost all cellular processes have one thing in common: they require energy. Without that energy, stored in the form of the adenosine triphosphate (ATP) molecule, cells are unable to perform vital functions that promote overall health. Our mitochondria are responsible for producing that ATP. Unfortunately, several internal and external factors are known to damage mitochondrial DNA; this leads to cell dysfunction and accelerated aging in the skin and body. Vitamin D helps protect mitochondrial DNA from this damage, leading to healthier skin, more resilient skin with a stronger skin barrier.
Although UV radiation is still present in the winter, exposure is much lower; this is why Vitamin D insufficiencies are more significant in winter. Vitamin D deficiencies are also linked to several inflammatory diseases and skin conditions, including psoriasis and eczema.
Winter skin tips
A weak skin barrier and a Vitamin D deficiency are not exactly desirable. We can avoid the negative impacts of cold weather with a few savvy tips! Here are some winter skin care tips and ways to address dry skin in winter.
- Drink lots of water. Clinical studies demonstrate that staying hydrated can change the skin’s physiology and improve its water retention capabilities. 
- Moisturize religiously. Moisturizing is a quick and easy way to avoid dry and flaky skin. Make sure to use a clean moisturizer without any irritants. Timeline’s Night Cream is an intensely hydrating cream, leaving the skin more resilient than before. This is a great option to promote long-term skin health. 
- Supplement Vitamin D. Studies recommend topically or orally supplementing Vitamin D to strengthen the skin barrier, reduce sun sensitivity, and promote skin longevity. 
- Use sun protection. The importance of using sun protection is not only relevant in the summer. While we all know that it is an essential element in anyone’s summer skincare routine,UV radiation is present all year long. UV radiation can penetrate through clouds, which is why a broad-spectrum sunscreen is needed all year long. Products that decrease sun sensitivity are also recommended to promote healthier skin.
- Eat nutrient-dense foods. Foods that contain antioxidants and essential fatty acids can prevent and repair cellular damage throughout our body, including in the skin.  Topical and oral supplementation of some antioxidants can also slow skin aging. Topical application is known to have a stronger localized impact on the skin, so consider adding an antioxidant to your winter skincare routine. 
- Utilize the power of Mitopure® (Urolithin A). Timeline's Skin Health products provide gentle power. Mitopure (Urolithin A) targets both intrinsic and extrinsic factors that contribute to skin aging without contributing to skin irritation or sensitization.
Timeline Skin Health Products
Winter skincare essentials
There are several cosmetic products you can add to your winter skin care essentials to moisturize dry skin and help protect it from UV damage. However, products that strengthen the skin enable it to retain moisture itself to stay hydrated. Timeline’s Skin Health products contain our proprietary compound called Mitopure®, a highly concentrated form of Urolithin A.
Mitopure® has several longevity-promoting properties when ingested orally or applied topically. In fact, this compound is the first and only bioactive clinically proven to re-energize cells by renewing their power sources, helping them combat intrinsic (biological) and extrinsic (environmental) aging factors.
Timeline’s Skin Health products are powered by Mitopure®. Mitopure® is clinically proven to improve skin resilience. Studies have demonstrated Mitopure's ability to promote collagen organization and assembly and to protect the skin from photoaging damage. This compound is also known to improve skin appearance, visibly reducing wrinkle depth and volume. 
Here are some Timeline products that will keep your skin healthy and hydrated throughout the winter season to add to your winter skin care essentials.
