This product offers a good level of protection against both UVB and UVA rays.
This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.
This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.
“The protection is lightweight, effective and leaves your skin looking luminous and youthful.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains gluconolactone.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
This product can also help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: gluconolactone.
This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, sodium hyaluronate.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: carthamus tinctorius seed oil, olea europaea fruit oil.
This product contains antioxidants (gluconolactone) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Filter by role to see what each ingredient is doing.
A weak sunscreen that offers some protection against the sun rays that cause sunburn (UVB), but does not offer meaningful protection against protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen. When used in low concentrations, helps to stabilize the product formulation
More about HomosalateA weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen
More about OctocryleneA synthetic ester of salicylic acid that is used to help disperse pigments and boost effectiveness of sunscreen ingredients. It is able to absorb UV light (working as an organic, or chemical filter), but is not approved as a sunscreen ingredient on its own
More about Butyloctyl salicylateOctisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen
More about Ethylhexyl salicylateOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
More about GlycerinAvobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.
More about Butyl methoxydibenzoylmethaneA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals
More about GluconolactoneHelps products spread more easily and works as an emollient to soften skin
More about Dicaprylyl carbonateHelps oil and water mix together
More about Sodium stearoyl glutamateTraditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin

More about Sodium hyaluronatePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
More about TocopherolA more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.

We believe that "Coola - Sun Silk Drops SPF30" can provide reliable sun protection based on the ingredients listed. It can protect from both UVA and UVB rays. This is great news because not all sunscreens with SPF ratings give UVA protection. (UVA rays do not cause sunburn, but still damage our skin and lead to early aging).
This sunscreen should also be hydrating enough to use without an additional moisturizer during the day. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: avobenzone 2.00% (declared), butyloctyl salicylate 3.50% - 5.20%, octisalate 5.00% (declared), homosalate 10.00% (declared) and octocrylene 6.00% (declared).
This product contains a bunch of common irritants, including ingredients that do not provide any known benefit for the skin. It might not be the best choice if your skin is sensitive. We assess the overall irritancy of this product to be high. For a detailed overview of all potential irritants: click here
