Sunscreens help to filter out ultraviolet (UV) radiation. Ultraviolet radiation (UVR) may cause age spots, dark spots, wrinkles, sagging as well as cancer.  The Sun Protection Factor (SPF) is a measure of how much radiation a sunscreen blocks. Broad spectrum sunscreens protect from both UVA and UVB. Sunscreen is the most important skin care product that should be used every day, even in winter to prevent signs of premature ageing.

Professional sunscreen products are not heavy, thick, or pore clogging.  These sophisticated sunscreens will benefit different skin types. To avoid sun damage, look for antioxidant ingredients like Vitamins E and C in the sunscreens.  For more sensitive skin, look for Titanium dioxide and Zinc oxide, because they do not penetrate the skin. They only accumulate on top of the skin and reflect or scatter UV waves, thus avoiding skin irritation. Otherwise, broad spectrum sunscreen can be used to absorb UV rays. Fragrance and perfume should also be avoided because they may cause photosensitivity, brown spots or age spots.

Sunscreen should be stored away from heat and direct sunlight (i.e., in a cool, dry place).  Expiration dates should be honored because the product’s integrity cannot be guaranteed, even if it may be effective for a few months after the date.

In short, wherever your plans take you, take your sunscreen along.  Don’t miss a day. Use it like medicine to avid age spots, wrinkles, sagging and cancer.  Your skin and health will thank you.

There are 5 main factors that cause hyper-pigmentation or brown spots, age spots, dark spots.


The sun is the major cause of hyper-pigmentation or dark spots. UV directly stimulates the protection of melanin. Melanin is your body’s way of protecting itself from UV. Excess sun exposure causes age spots or brown spots.

2- Irritation, Inflammation & Trauma

Have you noticed a dark spot after a healing pimple or discoloration from a scar? This is post-inflammatory hyper-pigmentation. Irritation to the skin can cause inflamation. DNA damage caused by inflammation activates the genes for melanin production. The injury causes an increase in pigmentation and scarring.

Irritation can come from many sources – too much pressure (from massage or incorrect extraction technique),  skin trauma or wounds, unprofessional laser treatments , over-exfoliation, even spicy foods and inflammatory diseases such as eczema.

3- Hormones

Changes in the balance of reproductive hormones (estrogen, progesterone) and stress hormones can cause hyper-pigmentation. This is the hardest kind to treat, because there is a ‘hidden’ factor behind the hyper-pigmentation or brown spots.

4- Chemicals

Certain chemicals can trigger a melanocyte to produce melanin. Artificial fragrance is a big one. Oxidized ingredients also cause brown spots. Pure Vitamin C is a perfect example – it oxidizes extremely fast, unless it has been correctly formulated (hard to find).

5. Medications

Certain drugs (anti-malarial, cancer, others) as well as heavy metals may cause dark spots too.

If melanin is produced in high concentrations or becomes “clumped”, they form age spots or brown spots.  These dark spots are not dangerous and can be removed.
