SIDE EFFECTS OF SUN PROTECTION

For many years, dermatologists have advised their patients to avoid the sun or to have limited contact; Because ultraviolet (UV) rays are the primary cause of skin cancers, exogenous skin aging, skin wrinkles and uneven pigmentation (freckling, spotting on the skin). Cosmetic patients are a group that is open to learning about the harmful effects of the sun and protection methods and is interested in the subject. If patients are protected from the sun within all skin protective measures and make it a behavior; It should be explained that they will not waste money on cosmetic products and procedures.

When the available data are examined, there are no systemic effects among the side effects triggered by chemical sunscreens. However, there are side effects that occur in the local (cutaneous) skin such as contact dermatitis, irritant dermatitis, allergic, phototoxic, photoallergic reactions, hyperpigmentation (spot).

Carriers of sunscreens, especially oily ones, can exacerbate acne with UV contact and cause comedones to form.

Chemical sunscreens that cause allergic contact dermatitis usually contain PABA, benzophenols, cinnamates and methoxybenzoyl methane.

Another point to remember; Ingredients added to sunscreens, such as fragrances and preservatives:

As a result, allergic reactions may occur in sensitive individuals.

Another issue to be clarified:

Sunscreens provide complete protection, increasing the frequency and length of contact with the sun. No sunscreen can block all of the sun’s rays. In fact, the FDA has not allowed the term sunblock to be written on the labels of sunscreen products for a while. Because protection in most sunscreens is limited to the short wavelength of UVB and UVA 2 (320 – 340 nm). The use of such products paradoxically increases contact with long wavelength UVA (320 – 400 nm). UVA ( 320 – 400 nm ) constitutes an important part of the UV rays reaching the earth’s surface and plays a role in the development of skin cancer, the formation of photodermatitis, and the formation of other skin diseases that are also activated by sun rays.

Interestingly ; The lowest protection against UVA activated pigmentation is provided by sunscreens with an SPF value of 45-50. This shows that selective high SPF sunscreens cannot be used as the only guide in comparison with recommended sunscreens for UVA protection…

Wishing you healthy days
