Product Description
DHC Suncut Q10 is a broad-spectrum SPF 50+ facial sunscreen that provides moderate sun protection from both UVA and UVB rays with powerful chemical-free physical blockers. Other megastar ingredients include brightening alpha-arbutin and coenzyme Q10 to lead your skin moisturizing. Hyaluronan and Rosemary extract are blended to lead your skin beautiful.
I purchased this 30ml size for $32 from the local Watsons. I started off with using it for the hands and body, but moved on to using it on the face, because I prefer this texture to that of Kanebo.
It comes in a sweet baby blue opaque coloured bottle, with a small tip that dispenses the contents. White in colour, the texture of the sunscreen is emollient with a slippery feel. It has a milky texture that is non-drying and non-greasy yet provides a smooth silicon feel after application. However, I did not quite fancy the feel that there is a coating of film on the skin.
Made in Japan, this product contains alcohol which is listed as the 6th ingredient in the list.
It contains the following ingredients for sunscreen protection.
Zinc Oxide :
Zinc oxide is one of only 17 active ingredients currently approved by the FDA for use in sunscreens. Upon application, zinc oxide particles sit on the outermost layer of your skin, the stratum corneum, where they scatter and absorb ultraviolet radiation, protecting your living skin below. Zinc oxide is unique among sunscreen ingredients in that it is truly a broad-spectrum blocker, protecting from UVA, UVB, and even UVC. (source)
Ethylhexyl Methoxycinnamate (Maximum recommended by FDA: 7.5%) :
Often listed on sunscreen products as Octinoxate, Ethylhexyl Methoxycinnamate (also called Octyl Methoxycinnamate) is used in products that are applied to the skin to absorb, reflect or scatter UV rays; it protects the skin from sunburn and other damaging effects of the sun. Ethylhexyl Methoxycinnamate also protects cosmetics and personal care products from deterioration caused by UV rays and allows them to last longer in high UV conditions.
It is a chemical sun blocking agent that absorbs ultraviolet radiation in UVB range.
However, when Octinoxate is exposed to sunlight, "it is converted into a less UV absorbent form hence it is not very stable. This conversion can be partly prevented by certain other UV blockers, particularly bemotrizinol (Tinosorb M).
Note that if Octinoxate combined with Avobenzone, it degrades even faster.
According to the EWG, Octinoxate is a moderate hazard, primarily because it can lead to developmental and reproductive toxicity through enhanced skin absorption. It can produce estrogen-like effects and should not be used by pregnant women and children.
Benzophenone-3 (Maximum recommended by FDA: 6%) :
Benzophenone-3 which is also known as Oxybenzone has a high hazard of 7 according to EWG, which is a sunscreen ingredient associated with photoallergic reactions as it absorbs through the skin in significant amounts.
Acting primarily as a photostabilizer and sunscreen, it is classified as a "chemical" sunscreen agent which is inadequate when used alone. Benzophenone-3 absorbs UVB and short UVA rays but is a relatively weak chemical UV absorber. By absorbing UV rays, it also helps preserve the integrity of other cosmetic ingredients, preventing their deterioration under the sun.
It has been shown that the product penetrate the skin and cause photo-sensitivity. As a photocarcinogen, it has demonstrated an increase in the production of harmful free radicals and an ability to attack DNA cells.
The FDA has approved the use of Oxybenzone as a safe and effective OTC sunscreen ingredient, but only in concentrations up to 6%

Butyl Methoxydibenzoylmethane :
In the United States, when this ingredient is used in sun protection products, it will be listed on the label as Avobenzone. Avobenzone, when applied to the skin, absorbs UV rays. In addition to causing sunburn, UV radiation is a significant cause of premature aging of the skin and contributes to the development of melanoma and other forms of skin cancer.
According to this source, tests have revealed Avobenzone’s tendency to significantly degrade in light over time, lessening its sun protection capabilities. For this reason, most sunscreens containing the ingredient also include photo-stabilizing ingredients like octocrylene.
Avobenzone appears to be relatively non-toxic and non-irritating to the skin. However, because it is often used in conjunction with photo-stabilizers, there is a greater risk for skin irritation and low-level toxicity. Furthermore, some studies have demonstrated it to be absorbed by the body and secreted into urine, and is therefore not recommended to use on children or pregnant women
In this link, the writer mentioned that though this ingredient may be a somewhat more safe product than oxybenzone but after it has been on the skin for a period of time, it could actually lead to increased reactive oxygen series (free radical damage) from what has penetrated a little deeper into the skin.
