sunumbra daily spf 15

Isn’t SPF 15 a bit too low for daily wear? That’s the question that popped into my mind when I heard Sunumbra was releasing a new sunscreen called Sunumbra Daily SPF 15.

I get what they’re doing. The lower the SPF, the lighter the texture. No greasy mask on your face. No white cast. But does that compromise protection? It depends. There’s a time and a place for SPF 15 in your skincare routine, too. Here’s what I mean:

Key Ingredients In Sunumbra Daily SPF 15: What Makes It Work?

ZINC OXIDE

Like all Sunumbra sunscreens, Daily SPF 15 uses zinc oxide (9%, non-nano, non-coated). This white mineral protects ON ITS OWN from the entire UV range. Plus, it’s so gentle, even babies can use it.

You’ve probably heard that zinc oxide creates a shield on the skin that reflects UV light away from it. That’s only partially true. It deals with some UV rays that way, I’ll give you that. But for the most part, it acts like every other UV filter: it absorbs UV rays and converts them into a less damaging form of energy (heat).

The catch? Zinc oxide can leave a white cast behind. And its thick texture can feel greasy on the skin. Maybe it’s because there’s not too much here, but this sunscreen feels nice and clear to the touch.

ANTIOXIDANTS

Did you know that antioxidants help boost the effectiveness of your sunscreen? Here’s the deal: SPF 15 blocks only 93% of UV rays. The remaining 7% penetrates into your skin, generating free radicals. It’s the first step of a chain reaction that leads to wrinkles, dark spots and, in the worst case scenario, cancer.

That’s where antioxidants come in. The skin’s police, these little molecules patrol the body looking for free radicals to destroy. The more antioxidants you use, the more free radicals damage you can avoid. Sunumbra Daily SF 15 is loaded with antioxidants. Here are the highlights:

The Rest Of The Formula & Ingredients

  • De-ionised water: Water purified from minerals that may otherwise compromise the formula.
  • Baobab (Adansonia digitata) oil: It has powerful moisturising and antioxidant properties.
  • Sodium olivoil glutamate: An emulsifier that keeps all the ingredients well-blended together.
  • Cetearyl alcohol: It makes skin softer and smoother.
  • Glyceryl stearate: It’s both an emollient that makes skin soft and an emulsifier that keeps the formula well-blended together.
  • Carnauba wax: Another emulsifier that prevents the formula from separating.
  • Galactoarabinan: It increases the dispersions of UV filters, thus enhancing their protection.
  • Aspen bark extract (populus tremuloides): It functions as a preservative, helping your sunscreen last longer.
  • Kigelia extract: It has soothing and preservative properties.
  • Aloe vera extract: It’s super soothing and helps reduce UV-induced irritation.
  • Nicotinamide: A form of Vitamin B3, it moisturises skin, soothes irritations, and has antioxidant properties.
  • Tyrosine: An amino acid that moisturises skin. Brands will tell you it does all kinds of skin, like reducing wrinkles or brightening skin, but there’s no proof that’s the case when applied topically.
  • Allantoin: A soothing agent that reduces redness and irritation.
  • Xanthan gum: It thickens the texture of cosmetics.

Texture

For a zinc oxide-based sunscreen, the texture is so lightweight. It feels a bit waxy, but it takes only a minute to absorb, and doesn’t leave neither a greasy residue nor a white cast behind. Phew!

Fragrance

It’s fragrance-free. Yes, it smells a bit sunscreeney – that’s just the natural smell of the ingredients for you. But there’s no artificial fragrance that may irritate sensitive skin.

How To Use It

Generously. Apply at least 1/3 of a teaspoon for the face and neck and a small glass shot for the body. Reapply regularly (at least every couple of hours in the sun).

P.S. Pat, don’t rub. When you rub sunscreen in, you’re actually rubbing some of it OFF your skin!

Packaging

Sunumbra Daily SPF 15 comes in a bright orange and blue tube. It’s both hygienic and practical. Most importantly, it doesn’t release too much product, so nothing gets wasted.

Performance & Personal Opinion

Sunumbra Daily SPF 15 is one of the most aesthetically pleasing mineral sunscreens I’ve tried.It’s not as runny as Asian sunscreens, but it’s not as thick as toothpaste either. You can pile it on without feeling like you’re wearing a thick mask of grease.

On my pale skin, the white texture leaves no cast behind either. Of course I apply sunscreen afterwards, but not because I need to disguise the Caspar-like cast. Talking about makeup, this sunscreen makes a good base for it. What it can’t replace is moisturiser. If you have dry skin, slather it on before you apply anything else.

But how does it protect from UV rays? SPF 15 may be the minimum dermatologists recommend, but it’s incredibly low. It’s enough for daily use in winter when the sun hides under thick clouds and goes bad to sleep after a few short hours. But come summer, you’ll need much higher protection.

What I Like About Sunumbra Daily SPF 15

  • Fairly lightweight and fast-absorbing texture for a mineral sunscreen
  • Fragrance-free
  • No white cast
  • Contains antioxidants that can fight premature wrinkles
  • Makes a good base for makeup

What I DON’T Like About Sunumbra Daily SPF 15

  • SPF15 is very low and suitable only for very dark winter days

Who Should This?

  • Normal skin
  • Combination skin
  • Anyone who’s looking for a winter sunscreen

Does Sunumbra Daily SPF 15 Live Up To Its Claims?

CLAIM TRUE?
A light, non-whitening, moisturising, DAILY sunscreen that provides excellent balanced protection from both the UVA and UVB rays, as well as antioxidants to fight off free radicals that bombard us every day. It’s not moisturising, but everything else is true.
Can be used by anyone with dietary, environment or sensitive skin concerns. Yes – unless you’re allergic to one of the ingredients.
Active natural skin nutrients and antioxidants to help reverse the effects of radiation damage. Some antioxidants can soothe UV-rays induced inflammation. Just don’t expect them to get rid of wrinkles or dark spots.
Sunumbra daily is made exclusively from natural and organic ingredients. It is the unique combination of these ingredients that has enabled the total replacement of harmful chemicals to be found in many sunscreens.  There are NO harmful chemicals in sunscreens. This is just fearmongering.
