Hi all,
I recently moved from a very hot and sunny place to the south of England. Out of habit I continued using SPF each morning, but I feel a bit ridiculous doing so when the UV index indicates low radiation. Most days the sun is not out at all, it's not dark but everything is in shade, and it is probably going to become gloomier and gloomier as the winter progresses.
I had bad hyperpigmentation and took care of that and I'm now using retinol and BHA in the evening. Would you say it's best to continue using SPF every morning or maybe I'm just blocking myself from getting vitamin D and not gaining any actual benefit?
Thank you!
Hey is there any way to see your own skin damage using an app or something like that? Like not one that’s like this is what you’ll look like in 10 years if you don’t use sunscreen etc? Like how the add shows how sunscreen works on someone’s face using a uv light? Thank you
My SIL has this skincare and she keeps talking about on the molecular level with nanotechnology - but I can’t help to be sketched out by it. She tried to explain to me that it just uses “smaller molecules”. But my main question is, “Is Molecular Nanotechnology legit when skincare companies say that or it’s just filler?” The skincare on topic is about Atomy Skincare
I found a nice airless pump bottle that I want to use for storing Garnier Ombrelle's Complete SPF 60. I have reached out to Ries to double check, but I believe their bottles are made out of polypropylene (PP).
The active ingredients for the sunscreen are:
And the inactive ingredients are:
I did come across this FDA study in which they tested custom sunscreen formulas for stability up to 1 year. They used PP for the storage and all of the formulations remained stable for the full duration. That leads me to believe that PP is fine for decanting sunscreen into.
Questions:
Is decanting sunscreen alone enough to reduce sunscreen effectiveness by more than a negligible amount?
Would it be safe to decant this formula into this bottle?
In general, are there any ingredient/material combinations to watch out for?
I'm a 16 year old girl who loves shopping at sephora and since my birthday is coming up, i'm thinking of asking for some skincare and makeup. however, i'm not sure if any of these are okay for teens / young skin to use. i've tried looking online for reviews but they are rather mixed. would any of these be unsafe / harmful for young, generally clear skin?

There are so many different kind of masks from the basic sheets masks, the gel masks from Dr. Jart, the rubber masks from Dr. Jart, DermaModeling masks from Mediheal and collagen masks from Biodance. What makes each one so different and what should I be using each for?
So I'm a 35 year old woman with very sensitive skin that can dry easily. Due to a compromised immune system, I have to start making up again (basically until spring). Last winter when I had to do the same thing, I got a lot of breakouts, and I'm wanting to avoid that this year. So does anyone know of any wipes I could use periodically throughout the day to clean my skin? I don't wear makeup, so I'm not worried about needing to reapply anything. Thanks for anyone who has ideas.
(Sorry for any mistakes, english isnt my first language) So my husband(28m) has extreme dry issues on his eyelids. I did some research and it might be eyelid eczema. There is a lot of hyperpigmentation around his eyes and texture like loose skin around his eyes and eyelids. He also has sinusitis mostly due to the humid country we live in. Because of his sinus issues, his eyes get itchy or irritable so he rubs his eyes unintentionally making it worse. We have tried, vaseline, moisturizers, graham eyelids and face eczema cream, eucerine. Its not getting better. We dont want to go to a doctor as we dont have good doctors in this country and moving is not an option. Or going abroad for medical. Is it possible to fix this without steroid creams from doctors? I would like to add that he sweats A LOT from his head and face, more than normal. This has also been an issue as his face gets too hot and he rubs his eyes or tries to wipe the sweat off with his hands. Thick moisturizers is too heavy as he sweats all the time from his head and face.
It just seems ridiculous to me that Skinceuticals seems to have a monopoly on effective vitamin c serums.
I know I'll just go without as opposed to paying over 50 for anything skincare related.
Is there another type of vitamin c serum that performs well? Not even as well as skinceuticals, just well?
Hi everyone, as I am trying to perfect my skincare routine, I have been checking out different websites/apps. I want to find a good way to avoid ingredients which may be a health hazard or which may not work well in combination. Additionally, it would be great to get some help trying to figure out if I am missing any important active ingredients for my skincare concerns. I havent been fully happy with any such site yet. What do you use? Do you have any good recommendations? Preferrably free if possible.
I am so overwhelmed by all the information online about hylauronic acid, rose water toner, green tea toner, vitamin a/c, glycolic acid acid, sunscreen, what to put and when, anything to simplify this?
Hey everyone, I made a DIY moisturizer with mango butter, Shea butter, some light oils, water, emulsifying wax and phenoxyethanol. The Shea butter smell is kind of overwhelming. Anything natural I could add in besides essential oils to mask the smell? Or maybe suggestions on the formula? It has a slightly colloid-ish like look to it at times

I have strawberry legs and I have accepted that but also multiple ingrown hair and red spots. I can not shave my legs as when the hair starts growing back it itches so bad. I always wax my legs but this last time made me itch for days and now I have these red spots. I exfoliate in the shower but the ingrown hair are so deep in the skin's surface that nothing seems to work for me. I tried the Skin Doctos' Ingrown Go to shed the top layer of the skin and that did not help as well as I still have deep ingrown hair. Is their a specific way of exfoliation or products that I need to try?
Please any suggestions are appreciated!
My GP doesn't want to do allergy testing because it is not accurate according to him.
