Phototypes: the starting point for protecting your skin in the sun
What is it and how to recognize your phototype?
Phototype is a characteristic that classifies different skin types based on their reaction to sun exposure and UV radiation.
Our phototype is determined by the amount of melanin in our skin, consequently telling us how it reacts when we sunbathe, that is, how much and how we tan.
SUN EXPOSURE
The atmosphere
The atmosphere absorbs much of the sun's radiation, including UVC rays, which are very harmful to humans.
UVB and UVA rays on the contrary
strike the skin surface, resulting in different effects due to different penetration capacity.
THE SUN.
Luminous energy and skin
The light we see, visible light, is composed of a beam of waves of different lengths.
Sun exposure can be intentional and has the purpose of getting a tan, or NOT intentional, related to everyday outdoor activities: work, recreation, sports.
SUN EXPOSURE
The positive and negative effects
POSITIVE EFFECTS
- Indispensable to life - Warmth
- Anti-depressant effect - Anti-rachitis: synthesis of Vitamin D (15 minutes a day over the course of a year is sufficient)
HARMFUL EFFECTS
-IMMEDIATE
Rapid-onset dermatoses: Solar erythema -Sunburn
- Polymorphous solar dermatitis
- RETARDED.
Dermatoses arising years later: Photoaging - Photoinduced tumors
SUN EXPOSURE
In the sun without risk
Avoid the middle hours of the day (12-4 p.m.)
- Avoid prolonged exposure and sunburn
- Expose yourself gradually to sle
- Protect yourself with hat and T-shirt, sunglasses
- Use cream, sunscreen sprays by applying them carefully and
on all exposed areas
- Repeat application every 2 hours and also when you are
already tanned
- Artificial tanning does not effectively protect
from the sun's rays
