all you need to know about sunscreens
Exposure to UV rays from the sun as well as mobile phones and laptops is the number one cause of skin ageing. Every moment we are exposed to daylight, the skin damage gets compounded like money in the bank. Unprotected skin can show signs of premature ageing, wrinkles, dull and uneven skin tone, hyperpigmentation, among others. The best defence against this type of skin damage is to limit daylight exposure and protect your skin with Broad Spectrum SPF. Here is everything you need to know about sunscreens, how they benefit the skin, and what type of sunscreen would work best for your skin type.
what are UV rays and how do they affect the skin?
While UV rays are invisible to the naked eye, they cause significant skin damage. About 95% of UV rays that reach the ground are UVA rays, which cause early skin ageing, while the other 5% are UVB rays, which are chiefly responsible for ‘sunburns’.
UVA (ageing) rays generate free radicals, which can lead to premature skin ageing, hyperpigmentation and wrinkles. UVA rays can penetrate deeper into skin, all the way to the dermis. UVA rays are always present and can penetrate glass, which is why it is imperative to wear sunscreen every single day, even when you are indoors.
UVB (burning) rays cause sunburns. These high-energy rays typically penetrate the epidermis and can cause long-term damage to the skin.
what is SPF?
The Sun Protection Factor (SPF) in sunscreen is an indication of the level of protection a sunscreen could give to prevent burning.
SPF 15, 20, 25 = Medium Protection
SPF 30-50 = High Protection
How does SPF work?
SPF15 blocks 93% of UVB rays; SPF30 blocks 97% of UVB rays; and SPF50 blocks 98% of UVB rays.
Doubling the amount of chemical agents to produce SPF 50+ provides little extra protection.
Note that mixing one SPF30 sunscreen with another SPF50 sunscreen will not make your sunscreen SPF80; on the contrary, the sunscreen will get diluted and you will be protected with SPF40. It is best not to mix one sunscreen with another, or anything else, unless the sunscreen is specifically designed to be mixed in with something else.
will using sunscreen prevent vitamin D production?
The lack of Vitamin D is another growing concern amongst Indians today, so this is a legitimate question. The answer, however, is no. Since sunscreens cannot block 100% of UV rays, Vitamin D production can be achieved even while wearing sunscreen. Studies have shown that with a small amount of incidental exposure during daylight hours, such as walking to the car or exercising in the balcony, the skin can produce sufficient levels of Vitamin D.
You should always apply sunscreens 30 minutes prior to exposure, even if you intend to boost your Vitamin D levels. We strongly recommend that you wear sunscreen every day, regardless of the weather, whether you’re indoors or outdoors, or your skin type.
different types of sunscreens
physical sunscreen (also known as mineral sunscreen)
- How it works: This type of sunscreen sits on top of skin and reflects the sun’s rays off it like tiny mirrors.
- Benefits: It is better suited for sensitive skin as it prevents the UV rays from penetrating and does not get absorbed into the skin.
- Ideal for: all skin types and conditions, including sensitive skin and post-resurfacing treatments.
- How it works: Chemical sunscreen absorbs and transforms the sun’s rays into heat.
- Benefits: These tend to feel light and look unnoticeable on any skin tone, and are more water resistant and thus useful for sports or swimming activities.
- Ideal for: Chemical sunscreen is suited to most skin types and conditions.
how to choose a sunscreen based on your skin type?
Sunscreen is one of the most important elements of your skin care routine and Dermalogica offers a few which are suitable for all skin types. These take care of your skin, protect it from UVA and UVB rays, and environmental assault like free radical damages, and help you live in your healthiest skin.
Do remember that sunscreen must be generously applied all year round, whether indoors or outdoors. Sunscreen provides protection not only from the sun’s harmful UVA and UVB rays, but also from those emitted by blue screen devices, like laptops and smartphones. Sunscreen can be either physical or chemical, and it’s important to understand the product and your own skin type before incorporating one into your routine.
what is dry skin?
If your skin often feels tight, especially after bathing, you notice that it is flaking or peeling, and it feels rough to touch, it looks grey or ashy or excessively red, then you likely have dry skin. A simple test to check whether your skin is dry is to lightly scratch the skin with your nail - if a grey line develops on the skin, then your skin is dry. Dry skin often worsens in the winter months and generally needs a lot of moisture and hydration through the year. Dry skin, if not cared for properly, can cause fine lines, cracks, and skin to age quickly. The sunscreen you choose should not only protect you from the sun’s harmful UV rays indoors or outdoors, but should provide hydration and nourishment as well.
what is oily skin?
Oily skin is characterised by a constant shine or greasy layer on your skin, enlarged pores and acne or breakouts around the oilier areas, and the fact that your makeup just won’t stay put. This is further exacerbated in the summer and monsoon months when the excess sweat makes your skin oilier still. Oily skin needs to be handled with care and products that are specifically suited to oily skin types, so as not to further increase the sebum produced or worsen any skin concerns like clogged pores or breakouts.
what is sensitive skin?
If your skin easily reacts to new products and fragrance, and tends to get easily red or irritated, chances are your skin is sensitive. Sensitive skin must be protected from the sun and other harmful free-radicals, especially during the summer months when the rise in the temperature may already affect the skin internally. Using skin care products meant for sensitive skin will minimise the chances of irritation and flare-ups.
If you have no such complaints from your skin, then congratulations, you have normal skin! This means that you can choose skin care products meant for ‘all skin types’ or even products labelled ‘oily to normal’ or ‘dry to normal’, depending on which skin type you identify with more.
