We are in over our heads with the summer and heat. The ill-effects of this heat on our skin are countless. Umpteen sunscreens are available to make your life easier. But did you know you can bifurcate sunscreens into two major types? Let me give you a few further details.
Chemical sunscreens are made up of certain ingredients that penetrate the epidermis of our skin and absorb the UV rays themselves. This avoids the harmful rays from being absorbed in the skin. Thus, the sunrays do not hamper the skin but instead get absorbed by this sunscreen. Certain amount of chemical sunscreen is almost always present in our cosmetics.
Thin in consistency,
Do not require too much,
Not heavy on the skin.
Needs to be applied 10-15 minutes before stepping out,
Discolouration of skin is highly likely,
Not suitable for sensitive skin,
May give rise to skin problems like redness and pimples due to increase in internal skin temperature.
These sunscreens act as a shield between our skin and the sunrays. It does not absorb the harmful rays but reflects these rays away from the skin. Physical sunscreens are present in organic and natural beauty products.
Apt for sensitive skin,
Protection against UVA and UVB rays,
Non-camedogenic (does not clogs pores.)
Need to be applied generously,
May come off with sweat and water easily,
Tends to be thicker.
How do you difereniate a physical sunscreen from a chemical sunscreen?
It’s all in the ingredients.
Do not have blind faith on what has the product been labelled as. Instead read through the ingredients and decide for yourself.
Here is a list of ingredients that are not supposed to be present in a physical sunscreen:
Homosalate: A UV rays absorber and a probable hormone disrupter and pesticide absorber.
Octinoxate/octyl methoxycinnamate: A UV rays absorer. It is a probable endocrine disruptor and can increase the skin’s ability to absorb other toxic chemicals too.
Retinyl Palmitate: This is a skin conditioner and is an active ingredient. However, overtime use of a product with this ingredient may give rise to UV related skin damage.
Oxybenzone: Just like octinoxate, this ingredient may increase the skin’s ability to absorb other toxic chemicals present in the environment. It can also disrupt hormonal function.
Fragrances: When a product’s ingedients includes fragrance, you need to ge a little suspicious, since this could be a facade for many toxic chemicals. I say this because fragrance industry is not required to disclose the exact ingredients.
