How Does Dermalogica Biolumin-C Serum Work?
To get a better idea of what you can expect from Dermalogica Biolumin C Serum, it would help to understand how one of the premier ingredients in this skincare product works: vitamin C. So, how does vitamin C affect the skin, and how would it work in the context of this skincare product?
The first and possibly most well-documented effect of vitamin C on the skin is UV protection. UV rays can damage your skin by drying it out and exposing it to radiation. Some scientific studies have concluded that vitamin C actually negates the effects of UV rays and helps improve overall skin tone.
So this may be how Dermalogica Biolumin C Serum works for some people: it may balance skin tone and protect the skin from the effects of UV rays (sun spots, blemishes, etc.) On the other hand, vitamin C may not be universally effective, as some studies have come up with contradicting results and found no clear skin benefit of vitamin C.
Dermalogica Biolumin-C Serum Ingredients
For more insight into how Dermalogica Biolumin C Serum might work for you, let’s review the ingredients:
Tocopherol – Tocopherol is also known as vitamin E and is claimed to have antioxidant properties and benefit overall skin health. The National Institutes of Health has acknowledged that tocopherol may have photoprotective effects on the skin, but more studies are needed to confirm such benefits.
Lactic Acid – Lactic acid is part of a family of hydroxy acids that may replenish the skin with moisture. The Pubmed staff has stated that,
The results demonstrate that cosmetic benefits from the use of alpha-hydroxy acids are caused by modification of the skin surface, the epidermis, and the dermis. Although 5% lactic acid modulates surface and epidermal changes, 12% lactic acid influences both the epidermis and the dermis.
But as you can see, only a precise dosage would work, and it is unclear how much lactic acid is in this formula.
Sunflower Seed Oil – Natural oils are often used in skincare products to help maintain hydration and fortify the skin’s natural moisture barrier. In some studies, it has been found that sunflower seed oil is safer than another common oil, olive oil. Still, sunflower seed oil may cause side effects for people with sensitive skin.
Grapefruit Peel Oil – Grapefruit peel oil is another natural oil that is meant to stabilize the moisture barrier of the skin and help improve overall skin tone. The PubMed staff has also recognized that grapefruit peel oil may have anti-inflammatory effects on the skin that could reduce overall irritation.
Vitamin C – Vitamin C has been observed to reduce the appearance of sun damage and blemishes on the skin. It has also been demonstrated that vitamin C supplementation can help with acne by reducing overall skin inflammation. Some people may be extra sensitive to the effects of vitamin C, though.
Benefits of Dermalogica Biolumin-C Serum
Reduced Appearance of Wrinkles: It’s possible that by improving the overall moisture of the user’s skin, this product will reduce the appearance of wrinkles and fine lines. This effect should not be considered universal, though.
Sun Protection: The sun is one of your skin’s worst enemies and can rob it of elasticity. The makers of Dermalogica Biolumin C Serum claim that their product will protect your skin from damaging UV rays and even erase some of the damage it has already caused.
Anti-Inflammatory Effects: Dermalogica Biolumin C Serum may have anti-inflammatory and antioxidant effects. This may reduce overall skin irritation and protect it from the effects of free radical cells.
