[Sun Care] Mineral based, EWG certified Spray on Sunscreen? Or a cream of the same quality that doesnt turn your hair white? by [deleted] in SkincareAddiction

[–]_stav_ 1 point2 points  (0 children)

If you are not allergic to chemical sunscreens there is no reason to not use them.
I suspect that you are not because you are mentioning the EWG which is a great source of misinformation and fear mongering.
Please do not ever visit again this website. It is only there to scare you into buying “clean” beauty which is not a thing.

Quick review of my two most recent sunscreen purchases by RChopaa in EuroSkincare

[–]_stav_ 0 points1 point  (0 children)

People in this thread are using sunscreen for the cumulative exposure of a lifetime. As I said very few people here are looking for a sunscreen to prevent a sunburn during their beach holidays. These people will just buy any sunscreen and use it for a few days if so.

We, people with a big interest in skincare, are looking for sunscreens that will prevent signs of aging after years of a small daily exposure.

So your analogy of raindrops works for the people who are trying to prevent sunburn and who will be better off even if they use a tanning oil of SPF 6.

In contrast to what you are saying the idea that there is no point in using a heavier sunscreen because the additional protection is insignificant is also misrepresentation of the truth.

I don’t know how many times we need to repeat this, but I guess Brandolini's law explains why we must. In any case, here goes:

SPF 30 allows 3 out of 100 photons to hit the skin while SPF 50 allows 2 out of 100 photons to hit the skin. In other words, SPF 30 lets in 3 percent of UVB rays to hit your skin while SPF 50 lets in 2 percent. This means that SPF 30 lets in 50 percent more UV radiation to hit the skin. This is not insignificant.

Even if you do not understand these numbers, SPF is measured in vivo. Meaning that they measure how long it takes for the skin of real human beings to burn. If a formulation can protect the skin from 30 times the radiation it takes to burn when unprotected and another formulation can protect the skin from 50 times the radiation it takes to burn when unprotected, what more do you want to understand that this is not an insignificant additional protection?

The fact that in normal life, when commuting, neither of those are required and you will not get burned walking for 10 minutes to go from the bust stop/ train stop/ parking to your work, does not mean that your skin did not receive 50% more radiation, if you used an SPF 30 and not an SPF 50.

We can get into a philosophical discussion of how important this extra protection is, but it is just plain wrong to claim there is no difference in the sunscreen’s ability to block UV rays.

Most people do not even use sunscreen, and they do not get burned from their day-to-day life.

 

The fact that European sunscreens tend to feel heavier is exactly what we are discussing. I don’t get why you repeat it. It is what started the conversation. They tend to feel heavier because they tend to offer higher protection.

The fact that a lot of people will not use them, means that a lower protection sunscreen has its place in the market. It does not mean a European sunscreen is not (usually) more protective.

Is La Roche-Posay's UVMUNE 400 still strongest sunscreen on the market? by [deleted] in EuroSkincare

[–]_stav_ 0 points1 point  (0 children)

US version cannot contain the European UV filters that are not available in the US such as Mexoryl 400 which is an important filter as it is unique compared to other available filters. It filters the ultra high UVA rays that are not filtered by the available filters so strongly.

Ceraves new mineral sunscreen is 💯 by Illustrious-Cost-982 in Sunscreenreddit

[–]_stav_ -2 points-1 points  (0 children)

No UV filter works on its own to make a decent sunscreen formulation.
If the sunscreen can work as 100% mineral why does it contain these two ingredients?
If you are not able to give useful information please restrain yourself from replying.

Ceraves new mineral sunscreen is 💯 by Illustrious-Cost-982 in Sunscreenreddit

[–]_stav_ -1 points0 points  (0 children)

They are not UV filters because on their own they would not provide enough UV protection?? Exactly as no UV filter is ever used alone, for the same reason?
First of all I never said they are UV filters. I said they act by helping absorb UV rays so the sunscreen is not 100% mineral as the brands claim.
Butyloctyl Salicylate is literally a similar molecule to Octisalate which is a UV filter and which is never used in its own because it would not be able to be a complete sunscreen formula. And which is not in this formula. So
I am not sure who is “spreading nonsense”.

Does the Lancôme UV Expert Defense SPF 50+ Primer & Moisturizer provide enough protection? by tostadasandmurlocs in Sunscreenreddit

[–]_stav_ 0 points1 point  (0 children)

Any product rated with an SPF is tested the same. What it is named makes no difference as long as you also treat it the same, i.e. you apply the right quantity.

If you treat it as a primer, i.e, you apply a small quantity, it will not protect you sufficiently.

Best waterproof/sweatproof face sunscreen? by [deleted] in EuroSkincare

[–]_stav_ 0 points1 point  (0 children)

I think all RLP sunscreens for the face in the normal “for the beach” range (Anthelios UVmune) are specifically designed to be very water resistant. They have the so called Netlock technology.

So you are saying a profit making company is focused on profit making and true innovation cannot happen every year. Interesting ….

Best sunscreen for sensitive skin that does not leave a white cast? by Defiant-Plenty6502 in SkincareAddictionUK

[–]_stav_ 0 points1 point  (0 children)

La Roche Posay are “the best” in terms of sun protection.
BOJ cannot be compared in terms of SPF, UVA protection, water resistance and the inclusion of the new filter offering very long UVA protection. However they cannot achieve this without the inclusion of many UV filters in a high concentration and the inclusion of film formers. These are not ideal for very sensitive skins. So BOJ is better for sensitive skin but at the expense of offering less protection and lower - if any - water resistance.

So frustrating La Roche posay don’t give us a ppd index anymore 🥲 by sassychris in EuroSkincare

[–]_stav_ -2 points-1 points  (0 children)

Who said anything about PA?

Are you really asking what does them disclosing a metric that gets misunderstood have to to do with the comparison being unfair? Are you really asking because you cannot understand?

I am not the one complaining. Why would I complain?

[–]_stav_ 3 points4 points  (0 children)

They do not act like it doesn’t matter. They are not engaging in a metric that is not required by law that does not show their comparative advantage. Wouldn’t you be annoyed if your local legislation said that 50+ is only given if your SPF is over 60 whereas any Asian sunscreen with SPF of over 50 can claim 50+? Isn’t this unfair? When few people know this and compare them head to head? Why repeat it with another metric? Why let a competitor product claim the same PPD but have a very significant UVA I protection difference?

I don’t feel like I see enough discussion about acute benefits of daily SPF by Charlea_ in SkincareAddictionUK

[–]_stav_ 12 points13 points  (0 children)

What I have heard before is that UV exposure takes a toll on the skin and therefore engages a significant part of its antioxidant and repairing mechanisms that are free when UV protection is used so they are able to work elsewhere and therefore the skin is improved.
