Ask Our Expert: What is the best type of sunscreen?

Wednesday, August 22nd, 2012

 

Q: What is the best type of sunscreen?

A: Historically, it has been shown that physical sunscreens provide the best protection against both UVA & UVB radiation and are less likely to cause skin irritation.  Dr. Castillo, cosmetic surgery and anti-aging expert  https://www.cosmeticplasticsurgery.com/ recommends medical-grade, physical sunscreens to all his patients.

There are two divisions of sunscreen ingredients; physical and chemical. Physical sunscreens reflect the UV radiation while chemical sunscreens absorb the UV radiation and break it down within the skin. Some sunscreens contain both a physical and a chemical component.

There are two types of physical sunscreens available; zinc oxide and titanium dioxide. Both provide broad spectrum UVA and UVB protection. Today, these ingredients can be found in finely micronized, nano-sphere  form which allows for ease of daily use. Not only does zinc oxide and titanium dioxide provide needed broad-spectrum coverage but they are also beneficial to those who have sensitive skin or are irritated by chemical ingredients.

You will typically find multiple active ingredients listed in chemical sunscreen.  Each chemical ingredient protects only against a specific portion of the UV spectrum. Be aware that at this time many over-the-counter sunscreens protect against UVB rays only, although there are a few chemical ingredients like Oxybenzone that do offer UVA/UVB protection. Therefore, when purchasing over the counter sunscreen, it is important to examine the label for the claim “broad-spectrum.”  Also look for a sunscreen that says “very water resistant.”  However, keep in mind that even the best water resistant sunscreens can only protect you for 80 minutes.  Then you will need to re-apply.

With inconsistent OTC product labels and the idea that active ingredients in sunscreens differ from manufacturer to manufacturer it can be difficult to decipher all of them so I have provided at chart of the more common ingredients found in sunscreens.  When in doubt whether a sunscreen will effectively protect you and your family, I recommend selecting a medical grade sunscreen from your local cosmetic surgeon, plastic surgeon or dermatologist. Our patient’s favorite sunscreens are:

Sun Defense by Castillo MD Skin Science, which offers medical grade 12% Zinc Oxide, 7.5% Octinoxate broad-spectrum UVA/UVB protection

Prime Defense by Castillo MD Skin Science, which offers 10% Titanium Dioxide, 4% Zinc Oxide broad-spectrum UVA/UVB protection with an added skin primer.

 

Chemical & physical ingredients found in sunscreens.

Ingredient:                                            Ray Type:

Avobenzone UVA
Dioxybenzone UVA/ UVB
Homosalate UVB
Octocrylene UVB
Octyl methoxycinnamate UVB
Octisalate UVB
Oxybenzone UVA/ UVB
Padimate O UVB
Mexoryl UVA/UVB
Titanium dioxide UVA/UVB     broad spectrum
Trolamine salicylate UVB
Zinc oxide UVA/UVB     broad spectrum

WARNING: You must actually apply the sunscreen to your skin.  Just purchasing it will not provide sufficient protection! lol

Say Goodbye to Chest Lines, Wrinkles and Brown Spots!

Wednesday, August 8th, 2012

 

Roxanne performs CO2 Micro-Fractional Laser Resurfacing to remove lines and brown spots of the chest.

I was speaking with one of Dr. Castillo’s breast augmentation patients during a skin rejuvenation consultation.  She explained to me that a few years back she had breast enhancement https://www.cosmeticplasticsurgery.com/cosmetic-surgery/breast-enlargement.cfm in Dr. Castillo’s Cosmetic Surgery facility in Savoy, Illinois and that she couldn’t be happier with her results and the entire Cosmetic Plastic Surgery experience.

However, she has some fine lines and wrinkles on her chest between her breasts along with a moderate amount of brown spots. She expressed that she would like to show off her new cleavage https://www.cosmeticplasticsurgery.com/photo-gallery/results.cfm?Category=10 without being embarrassed about having wrinkles between her new, perky breasts.  She asked if G.D. Castillo M.D. and Cosmetic Plastic Surgery Skin Restoration and Laser Institute offered skin treatments to remove the wrinkles and brown spots of the chest.

I explained to her that the vertical lines and brown spots she was describing are common among those who have been over-exposed to the sun. The sun breaks down elastin and collagen of the chest, creating lines, wrinkles, and sagging skin.  It also causes melanocytes (pigmented cells that create brown spots she is seeing on her chest) to over-populate the surface of the skin in attempt to protect itself from damaging UV radiation.

I explained to her that yes, we can help with her chest lines and brown spots.  To improve the look of her damaged skin, first, she would need to begin to protect her décolletage using medical grade broad-spectrum sunscreen 365 days per year.  UV radiation will create more severe damage to areas such as the chest, neck and hands. The characteristics of the skin of the chest, neck and hands simply cannot tolerate the same amount of UV radiation as the face. The skin of the chest is not as forgiving as skin surfaces such as the face when it is repeatedly over-exposed to the sun. The skin of the chest is thinner, containing less elastin / collagen.  As the elastin is broken down, lines, wrinkles and sagging of the skin WILL occur.

Unlike the face, skin of décolletage does not contain an abundance of oil glands.  Why is this a problem?  Having an abundance of oil glands is important because as oil glands cells divide, they can become almost any other type of epidermal cell.  Therefore, when cells get damaged, they provide new cells to help to restore your damaged skin.

The good news is there are a few ways to correct or at least improve the skin of your chest.

  1.  First, and most importantly, PROTECT your chest for the sun.  Use a medical-grade, broad-spectrum, physical sunscreen  every day of the year. I recommend one of two  physical sunscreens:  Sun Defense or Prime Defense By Castillo MD Skin Science.  Both have high percentages of physical block ingredients (Titanium Dioxide and / or Zinc Oxide) making them superior  choices for sun protection.
  2. Avoid tanning beds as UVA rays will only create more damage to your skin.
  3. Use UV protective clothing and a wide brimmed hat to provide additional protection.
  4. Consult G.D. Castillo M.D. or another Cosmetic Plastic Surgeon regarding the following treatment options:
    1. CO2 Micro-Fractional Laser Resurfacing – This will decrease the lines of your chest (décolletage) while building collagen within the treated skin.  It will also make a significant improvement to the texture of your skin and decrease or remove your brown spots or discoloration. More than one treatment may be necessary due to the delicate state of the chest skin.  Did you notice that I highlighted, underlined and italicized the “CO2” in CO2 Micro-Fractional Laser Resurfacing?  That is because CO2 is the key there!! CO2 Micro-Fractional Laser Resurfacing far surpasses other non-CO2 laser technology using a “similar” name such as “fractional” or “Fraxel”… https://www.cosmeticplasticsurgery.com/cosmetic-surgery/laser-skin-rejuvenation.cfm
    2. Medical Microdermabrasion – Multiple microdermabrasion treatments https://www.cosmeticplasticsurgery.com/cosmetic-surgery/skin-resurfacing.cfm will soften the appearance of your chest lines and lighten the brown spots over time.  Be aware that this treatment will not build collagen, provide tightening or remove the lines and wrinkles on your chest.  It is meant only to brighten the skin by removing the build-up of dead skin cells.
    3. Medical Grade skincare products – There are effective medical grades skincare products created to specifically treat the chest area.  These products will not solve your problem alone but work well to support and prolong the effects of the above mentioned treatments. Medical grade means that they are of a higher strength and must be over seen by a physician therefor these are not your average over-the-counter disappointments.
