Finding a Sunscreen to Suit Your Skin Tone
Our low down on the UV filters to look out for to avoid a chalky finish
We all know that daily sunscreen is essential for protecting us against skin cancer, as well as premature ageing of the skin. But finding a sunscreen to suit deeper skin tones can sometimes be a pain, so we wanted to give you the low down on which filters can leave you with a chalky finish, so you know what ingredients to avoid and find your ideal sunscreen.
There are two types of UV filter, which can be grouped into mineral/physical or chemical/synthetic. Mineral filters are ground white powders, which work by reflecting UV rays to prevent them causing any damage within the skin. This mechanism means they tend to leave a chalky finish on medium-deep skin tones. These will be shown on the ingredients list (aka the INCI), as the following:
Mineral/Physical UV filters
• Titanium Dioxide
• Zinc Oxide
• Titanium Dioxide (nano) - this is the exception, as this is ground so finely, to nano-sized particles, that is will have a lesser whitening effect on the skin so may be suitable for light brown skin tones, although we would still suggest proceeding with caution and sampling the formula first where possible.
Chemical/Synthetic UV filters
The rule isn’t as simple as avoiding mineral filters, as there is one popular chemical filter that you also want to keep an eye out for.
• Methylene Bis-Benzotriazolyl Tetramethylbutylphenol - this is a powder form chemical/synthetic UV filter which provides protection against UV through reflecting and scattering rays, as well as through absorption. This is insoluble, so is suspended in the formula and can leave a white cast.
Sunscreens are typically formulated with A) mineral-only, B) synthetic-only, or C) with a blend of both filter types. For medium-deep skin tones, we’d suggest opting for a chemical-only sunscreen formula, which does not contain Methylene Bis-Benzotriazolyl Tetramethylbutylphenol, and this should avoid any chalky finish on the skin.
