Ultimate Guide to Sunscreens VII : Sun screens and Vitamin D deficiency controversy (Indian Context)

There has been a lot of talks and controversy about if sunscreen usage leads to Vitamin D deficiency, Does sun blocks vitmain D synthesized in our body ? On first impression it kinda makes sense : Sunrays causes Vit D synthesis, and hence if we occlude sun rays by sunscreen, Vitamin D wont be synthesized, and hence the deficiency. Is it so ? Read on as we burst another myth here :

Ultimate Guide to sunscreens VI : Physical ( Inorganic ) Vs Chemical ( Organic ) Sunscreens

Back with my sunscreen series , today we'll know more about physical (inorganic) vs chemical organic sunscreen in an overview, not going into nitty gritty technical details !

Physical / Inorganic Sunscreens
Chemical/ Organic Sunscreens


Titanium Dioxide (TiO2)
Zinc Oxide

Octyl methoxycinnamate (octinoxate)

How do they work ?

Act by reflecting the sun rays, forming an occlusive baarier over the skin.

The nano/ micronized versions act as both physical and chemical, both absorb and reflect

Act by absorbing the sun-rays and converting radiation into harmless form.

UVA protection

Zinc Oxide
provides pan- UVA protection, while Titanium dioxide offers protection against a limited spectrum of UVA

Only chemical sunscreens containing meroxyl and avobenzone confers protection against UVA.

UVB Protection

Zinc oxide and titanium dioxide shield against UVB

All except Meroxyl and avobenzone
provide protection against UVB

Cosmetic / Aesthetic property

Have a thick texture, and due to its mineral pigments they reflect light, hence giving a white cast, especially TiO2
(For this reason the particles are nanonized made into smaller sizes, where they exhibit as partially physical and partially chemical sunscreen property)

Usually lighter in texture as compared to physical sunscreens. Also can be worked into gel forms or aesthetic liquids.

Irritation/ Allergy

Less prone to cause irritation as compared to chemical ones.
Remember ZnO is used in lactocalamine for soothing property

(If you are perpetually prone to sunscreen allergies, try using physical one)

Notoriously implicated in contact dermatitis and allergies.

All the ingredients, mostly avobenzone, octinoxate, PABA is widely reported to cause allergies and irritation


Stable when exposed to sunlight, unlike chemical sunscreens. HOWEVER the micronized/ nanoparticles absorb too, with reflecting so they may degrade too.

A few ingredients are quite unstable when exposed to sunrays, like avobenzone and octinoxate.
When the sunscreen molecules absorb UV rays they isomerize into other *unable to protect*  form slowly, and then re-isomerize into the UV filter. But continous sun exposure might cause more degradation, than regenration and thus compromising the protection.


Can be applied immediately before sun-exposure.

Should be applied atleast 20 minutes before sun exposure to create effective UV filter


Since it gets degraded less as compared to chemical sunscreens, reapplication time can be little prolonged

Re-apply atleast after every 2 hours for continous protection.

Free Radical generation

TiO2 can abosrb sunrays too, and hence are capable of generating free radicals and causing damage. Also micronized ZnO is being implicate to cause a little oxidative stress

The free radical damage propensity is much more with chemical sunscreens than physical
However please keep in mind the damage is  so so much lesser than what you’d face if you don’t wear sunscreen.
Its better to use sunscreen and use antioxidant at night to combat the damage.

Now I also wanted to talk about the toxicity and safety aspect of these, but that's a very debatable and elaborate topic in itself and deserves another post altogether.

Hope you found the post helpful :)

Tresemme Keratin Smooth Shampoo and Conditioner for Straight and Smooth Hair 

5 posts in sunscreen series are up, and 5 more to go. I thought I should break the monotony and do some reviews this week. I'd start with Tresemme Keratin smooth range. I was surprised when I saw the press releases about this product on the blogosphere some days back, because this product has been selling . and selling hot on medplusbeauty.com since I guess one and a half months now ! Given my obsession for straight-ish hair and my infatuation for tresemme, I picked it up without even a second thought, and using it since 20 days now.

Did it stand up to my expectations ? Read on to know more :

Ultimate Guide to Sunscreens IV : How much sunscreen you should apply ?

I hope you are liking this series. Next we are up to tell you 'how much sunscreen to apply'. The reason I am doing this post before 'how to choose a sunscreen', and 'how to apply a sunscreen' is because I feel the amount of application is more important than anything when it comes to sunscreen.Honestly if you dont apply enough, even the best of sunscreens would not give you the desirable protection, and you may end up feeling cheated, because in your mind you had chosen the best  sunscreen there is.

Often I have read in reviews of sunscreens, especially the tinted ones, where the reviewer would mention ' it is easy to blend, and a little is enough to cover up the whole face'. I just feel like saying, no it is not enough. No matter how you end up looking, little can never be enough when it comes to sunscreens. Not if you are expecting a decent protection.
