Understanding cosmeceuticals is paramount to enhancing the effectiveness of their daily use. As a medical practitioner I find that the most frequently asked questions regarding cosmeceuticals follow the same mold, so here is a roundup of topics commonly covered.
1. Price equates with quality for many consumers, however the most expensive constituents of a skin care product are the fragrance, the bottle and the packaging. Unfortunately, it´s important to understand that none of these contribute to the quality of the product itself.
2. A quality moisturizer should contain an occlusive agent to reduce water loss from the skin, a humectant, which draws moisture to the outermost layer of the skin, and some form of silicone, which combines both benefits. One should always review the ingredients list for these when purchasing a moisturizer.
3. Moisturizers do not remove wrinkles. They do, however, improve their appearance, due to increased skin hydration, so remember to include them in your daily skin care.
4. Topical vitamins and oral vitamins do not hold the same effectiveness for skin improvement. Although most oral supplements are more effective than topical vitamins, there are exceptions, such as Vitamin E, which is an effective emollient. Oral consumption of Vitamin E does not enhance skin texture, because internally Vitamin E can only function as an antioxidant.
5. Products that contain vitamins don’t reverse photoaging (sun induced skin damage) they merely help to reduce the appearance of photoaging. Only specialized treatment can treat photoaging effects, for which one should consult a dermatologist.
6. Sunscreens with SPF 15 and above provide more protection, however this increase is limited. While a SPF 15 blocks 93% and a SPF 30 blocks 97%, dermatologists may prescribe a lower SPF mostly due to the consistency of the product, since the higher the SPF is, the stickier the product is. Note that frequent reapplication of sunscreen is essential to achieve adequate sun protection.
I hope to have shed some light on the topic and promoted a better daily care routine for your skin. Know your cosmeceuticals and keep healthy!
