the science

A variety of sunscreen filters feature in this sunscreen to offer excellent broad protection at the highest level. Single filters include Ethylhexyl Salicylate (also known as Octyl Slicylate) is an organic compound of Salicylic Acid and 2-Ethylhexanol. The former absorbs UVB rays from the sun, the latter acts as a fatty alcohol adding water resistant properties to the sunscreen. Another UVB blocker is the commonly used chemical filter, Homosalate that shields the skin from sun exposure by absorbing UV light and converting it to heat so that it can’t cause DNA skin cell damage. It isn’t particularly photostable on its own and needs support from other filters to achieve this. Focusing on UVA protection, Diethylamino Hydroxybenzoyl Hexyl Benzoate is a new generation, chemical sunscreen agent that offers high UVA protection and photostability. It protects against the whole UVA range (320-400 nm) and is approved for use up to 10% worldwide excluding the US and Canada.
There are also two broad spectrum (offering but UVA and UVB coverage) filters that offer coverage of 280-400 nm. Both are very photostable, meaning there is little to no deterioration in the presence of UV light. They can also help to stabilise other filters within the formulation. Although it’s not US FDA approved, the first, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is considered one of the best sunscreen agents known today and remains widely available in other parts of the world like Europe, Australia or Asia. Featuring both physical and chemical agents, the second, Methylene Bis-Benzotriazolyl Tetramethylbutylphenol is a new generation filter. Its hybrid nature means that it’s organic, but is neither water nor oil soluble and works as a suspension of micro fine particles.

This sunscreen isn’t called a Hyaluronic Acid gel for nothing! There are no less than 8 different molecular weights and types of HA in the formulation (Sodium Hyaluronate, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Ascorbyl Propyl Hyaluronate, Hydrolyzed Hyaluronic Acid, Hydroxypropyltrimonium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Sodium Hyaluronate). Hyaluronic Acid is a Glycosaminoglycan, a vital naturally occurring substance of the skin which works to keep every aspect of skin stable, safeguarded and continuously renewed. Able to attract up to 1000 times its weight in water, it’s also a competent humectant, well supported by Glycerin and a hefty amount of Butylene Glycol, the latter also assisting to increase the effectiveness of other ingredients.
There are several other noteworthy inclusions to discuss. Niacinamide is a well tolerated form of Vitamin B3. It acts as a restorative agent to offer multiple skin benefits. It can brighten skin by inhibiting melanin production. It’s also an effective treatment against hyperpigmentation at concentrations of at least 2% and provides a strong defense against the appearance of discolouration and age spots. Niacinamide is additionally able to improve the appearance of enlarged pores, uneven skin tone, fine lines, dullness and to strengthen the skin surface. Antioxidant protection is provided by Tocopherol (Vitamin E) and Pine Bark Extract which help to neutralise free radicals and slow the formation of lines. Fig Extract also boosts antioxidant content and also offers some moisturisation. Together with Adenosine, this combination of ingredients presents a great anti-aging arsenal.
Soothing ingredients are also well represented in the formula, with popular extract inclusions from Centella Asiatica, Portulaca Oleracea and Houttuynia Cordata. Ceramide NP replenishes the skin’s natural levels of this major lipid to help support moisture barrier function.

the performance

The packaging of this sunscreen is ideal. The narrow opening permits the perfect amount of product to be dispensed cleanly and the screw top cap keeps it secure. The flat base also allows the product to be stored upright, encouraging the sunscreen to flow towards the opening, preventing the need to fiddle with the tube to get it out. The opaque plastic tube ensures it’s well preserved, not subject to unnecessary light and makes it highly portable. The six month use period is ample for a 50ml product that requires frequent application throughout the day.
The cream itself is glossy white and lacks any noticeable scent. The texture is lightweight but not overly watery so it’s easy to apply without mess. It feels creamy and velvety smooth, sliding across the skin without tugging or resistance. Applying the recommended amount is easy and doesn’t feel excessive, the product lacking any greasiness or oiliness. I find that adding it after my moisturiser has settled, encourages the sun cream to dry down within just a few minutes to a slightly dewy finish, giving my skin a healthy glow. Granted, I have just layered my multi-step hydrating routine beforehand, but after this final step, my skin continues to feel plump and comfortable. It doesn’t pill either, no matter how much you rub your skin afterwards. Furthermore, layers apply throughout the day effortlessly, lacking any feeling of suffocation or heaviness. In fact, skin gets a boost of moisture each time so it’s a refreshing top up of moisture and protection.

The formula is superb, and probably one of the very best I’ve tried. I love that it contains multiple sunscreen filters, five in fact, three single (2xUVB, 1xUVA) and two broad coverage (both UVA and UVB). Given the controversy associated with Korean sunscreens in recent times, this combination of filters reassures me that the high SPF rating claimed is in fact achieved. (Worth noting that most of the sunscreens that failed to meet their advertised sun protection employed only two gentle filters). Although both physical and chemical elements are used, the product lacks any white cast or density, keeping it comfortable and transparent on the skin, making it perfect for any skin tone.
Formulation really does tick all the boxes with no essential oils or fragrance plus no alcohol which is often incorporated into sunscreen to enhance texture and experience. There are also some proven skin loving inclusions, the hero being the 8 different molecular weights of Hyaluronic Acid, the hero hydrator of this line of products. Niacinamide is one of my favourite ingredients due to its versatility, easy tolerance and efficacy. As well as generally strengthening skin and improving pore appearance, it’s often a brightening source. As much as I love this sunscreen, I haven’t noticed this effect. It’s also nice to see a few calming ingredients, Ceramide NP for barrier fortification and some antioxidants in there too.
In terms of skin type, not only is this one suitable for any tone, I think it would benefit any skin type too. Oilier complexions will appreciate its lightweight nature while drier skin will love the hydration boost it provides. There are no nasty inclusions in the formula so sensitive skin will also appreciate its benefits.

the conclusion

The Isntree Hyaluronic Acid Watery Sun Gel is one of the best sunscreens I’ve had the privilege of trying. I have nothing bad to say about it. It’s light, comfortable, safe, affordable and most importantly, provides excellent sun protection. It truly is a cosmetically elegant formulation that delivers on all fronts and one I will definitely repurchase in the future.
