Dermaviduals® Suncream SPF30 provides the skin with what are classified as "new generation" sunscreens that can give a high level of UVA protection and have high photostability.  Creams with SPF30 absorb about 98% of UVB radiation. In other words, they allow you to stay about 30 times longer in the sun before an erythema (sun burn) will develop. 
Thermal radiation from the sun is quite stressful for the skin and excessive sun exposure can have some serious consequences  It is therefore advised to expose the skin in moderation to the sun even when wearing the protection of an SPF.  
This product contains a combination of these new generation sun screen agents that work well together. When combined they have the ability to absorb ultraviolet light over a wide range of wave lengths offering broad spectrum protection from UVA and UVB radiation and have excellent photostability. 
Information on the sunscreens in this product:
Butyl Methoxydibenzoylmethane  - also know as Avobenzone.  Protects against the whole UVA range 310-400nm which includes both UVA 1 and UVA2 with a peak protection at 360nm.  However it is not photostable and loses 35% of it's UV absorption capacity after just one hour which is why many sunscreens have to be applied regularly.  However Dermaviduals combines it with other sunscreens which increase it's photostability. 
Bis-Ethylhexyloxyphenol methoxyphenyl triazine - also known as Tinosorb.  This is considered one of the best sunscreen agents known today.  It is broad spectrum covering the whole UVA and UVB range - 280-400nm with peak protection at 310nm to 345nm.  It is very photostable, hardly deteriorating  at all in the presence of UV light and is also useful in stabilising other less stable sun screen agents.
Diethylamino hydroxybenzoyl hexyl benzoate - also known as DHHB - a "new generation" sunscreen designed for high UVA protection and high photostability  It gives sun protection in the whole UVA range (320-400nm) with peak protection at 354nm.
Ethylhexyl Triazone - another "new generation" sunscreen also known as octyl triazone and Uvinvit 150.  It gives the highest photostable absorption of all available UVB filters today.  It protects in the UVB range 280-320nm with a peak protection of 314nm.  It is odorless so works well in fragrance free formulas such as Dermaviduals.   
Diethylhexyl Butamido Triazone - also known as Uvasorb HEB.  This is known as "super photo stable" and loses only 10% of it's SPF protection ability in 25 hours.  In the world of sunscreen 2 hours is counted as photostable so 25 hours is quite considerable.  It requires only low concentrations to achieve high SPF values.  It protects in the UVB and UVA 11 range but not in the UVA 1 range with a peak protection at 310nm.  It is water repellant and water resistant.
Sun protection is important for all skins but it's worth mentioning that exposure to the sun while acne is active or in the healing stage can increase the chance of scarring.
Wearing an SPF can help to prevent that.
Sun protection also prevents UV induced free radical damage and inflammation that can exacerbate the sumptoms of Rosacea.
