Dr. A. Geronimo Jones is a dermatologist at Beyond Basics Medical Day Spa located at 9 Walkers Road, 3rd Floor. The document discusses the relationship between wavelength and frequency of light, the beneficial and harmful effects of UV rays from the sun, the different types of UV rays and their effects on the skin, conditions caused by sun exposure such as solar elastosis and poikiloderma of civatte, and how the UV index varies throughout the day based on location.

4. The wavelength and frequency of
light are closely related.
Wavelength-the distance between
successive crests of a wave. (or
base)
Frequency-the number of waves
that pass a fixed point in a unit of
time.
The higher the frequency, the
shorter the wavelength.
Shorter wavelengths are
higher energy and longer
wavelengths are lower energy

5. Wavelength – the
distance between each
wave.
Frequency – the number
of time the waves crash
against the shore in a
given time period.
The closer waves are
together, the more
frequent they hit the
shore…the more energy
that is produced.

7. Beneficial effects of UV
 Triggers vitamin D - Helps
strengthen bones and muscles.
 Helps some skin conditions –
Psoriasis and Eczema
 Helps moods – Pineal Gland
(Tryptamine) – improves mood (“Son
Worship”)
Harmful effects of UV
 Causes Skin CA – Gene mutations
leading to MM, BCC, & SCC
 Suppresses Immune System – Poor
repair of damaged skin
 Causes sunburn – Cells damaged,
blood flows to skin to repair (red)
 Ages skin – Damage to collagen

8.  UV-C: Most dangerous type of
UV. Can’t penetrate earth's
protective ozone layer.
 UV-B: Sunburn/*Skin cancers.
 UV-A: Premature skin ageing
(wrinkles & photoaging)/Skin
CA/damages collagen

10.  Tanning beds release UVA/
UVB to mimic the effects of
sunlight.
 But tanning beds damage your
skin just like the sun does.
 Tanning beds emit UVA 3X more
intense than natural sunlight!
 Major cause of skin cancer in US.

13. • Cutis Rhomboidalis
Nuchae
• Solar Elastosis
• Poikiloderma of
Civatte
• Eruptive Pustular
Dermatosis
• Solar Comedones
• Colloid Milium

21.  UV index varies throughout the day.
 Max. UV levels occur during the “Solar
Noon” (sun at highest point). 12-2pm
 Varies with geographical location
 When the UV index is over 9, UV-B is
extremely strong, and you will burn in
less than 15 minutes.
