Explained: The number 1 factor for damage to the skin is sun damage

Welcome to the blog of Lindsay

Lindsay van der Looij is co-owner of KNAP Institute and with her 14 years of experience she can call herself a very experienced skin specialist. She manages many specializations and is an expert in the field of anti-aging. Lindsay receives a lot of questions about her own anti-aging regime and lifestyle, both professionally and privately. In this new category’The Blog of Lindsay ‘she will keep us regularly informed with findings and tips & tricks in the field of anti-aging and lifestyle.

Today I would like to discuss the number 1 factor for damage to the skin; sun damage. I often get questions like how is it that I am still experiencing premature aging in addition to all my facials and expensive creams? Or how is it that those pigment spots are popping up again. The best thing you can do for your skin is always to protect it from the sun. And you do this not only against skin aging but also to prevent skin conditions such as skin cancer.

When you wake up on a beautiful spring morning and you take your dog for a quick walk before breakfast, it happens quickly that you do this without first sprucing up an SPF. Or went on a quick terrace visit whilde fully being in the sun with that pretty face without extra protection because it is only for half an hour? And Vitamin D is so healthy? Dear readers, we definitely need vitamin D but sun is really harmful to the skin and sun rays are responsible for skin aging, weakening and wrinkling for up to 90%. Of course we forget about it every now and then but my advice is do yourself and your skin a favor and make sure you have an SPF in every handbag, just next to your powderbox.

Which SPF should I use?

An SPF lubrication should be just as standard in your beauty regime as applying your day cream. You can of course also opt for a day cream that already contains an SPF. I myself use: !QMS medicosmetics Cellular Sun SPF 50. This sun block offers the highest protection against both UV A (available all year) and UV B (mainly in spring and summer). It is actually the perfect day cream that protects and repairs cells against skin aging due to sunlight. Tip: it is also important to rub your neck, décolleté and hands next to your face. Many day creams and some foundations have already included an SPF. Usually this is an SPF 15 but you can also find excellent products in which an SPF 30 has been processed. My advice is to always opt for the SPF 30. SPF 30 is fine for the winter months I think. If you have light skin and suffer from pigmentation and redness, I recommend to pick up an SPF 50 as standard. In the summer months I recommend an SPF 50.

Some SPF facts in a row:

SPF 15 blocks 93% of the UVB rays
SPF 30 blocks 97% of the UVB rays
SPF 50 blocks 98% of the UVB rays

How often should I smear?

Remember that a higher factor is not a license for less lubrication. The rule is (and not everyone is aware of this) that when you apply an SPF, the efficacy is usually only a few hours (according to studies about 2 hours). In my opinion the SPF 50 of! QMS offers protection for at least 4 hours, but of course that is still quite short. Some SPFs even have a shorter operation. For optimal care, you should apply the SPF several times a day (the most preferably every 2 hours) and this is especially important during sunbathing.

Sun tips

Do you want that nice brown color in the summer? Consider for example a spray tan or other self-tanning products. Please note; even after a self tanner, the skin must be protected with an SPF. It is certainly not the case that a self tanner makes a filter, as it were. Do you really want some sunbathing in the summer then do this preferably in the morning or in the afternoon and lubricate well and preferably stay under a parasol. Important: apply at least 30 minutes before sunbathing. And do not forget that it is absolutely a fable that you can not brown if you lubricate well. On the contrary, because with good lubrication you will become nicer and smoother brown without burning. After sunbathing, it is important to help restore the skin with a good moisturizer to prevent lines and dryness of the skin.

Sun protection from the inside

In addition to applying an SPF, you can also strengthen the skin from within by eating healthy and taking certain supplements that help to strengthen the skin from the inside.
For example, I use Laviesage Skin Protect and Laviesage Skin Balance. Skin Balance contains essential fats for healthy skin and circulation and Skin Protect provides optimal protection of the skin from the inside. These supplements strengthen the skin so that the skin can also better resist external influences and in case of damage, strong skin will recover faster.

Treat sun damage

Despite all the measures, it is often almost impossible not to suffer any damage at all. Fortunately, there are a number of treatments that can reduce the effects of sun damage on the skin or even make it disappear. Sun damage to the skin is also called ‘photo-aging’. The effects of photo-aging are often only visible as we get older and the most common complaint is the pigmentation spots. These spots are produced by the so-called pigment cells, which are located in the bottom layer of the epidermis. Unfortunately, the dark spots usually do not disappear on their own and can be experienced as disfiguring. They are most common on the face, on the hands, in the neck and on the décolleté.

In the clinic we treat photo-aging with IPL treatmentTIXEL treatment and peelings (especially the retinol peeling is very suitable) or with the Erbium laser treatment. Which treatment is most suitable depends on the severity of the damage and the objective. The aforementioned treatments also help for overall skin improvement, tackling fine lines and strengthening the skin. It is best to plan these types of treatments in autumn, winter or early spring. For example, the skin still has enough time to recover before the summer starts and we still get more sunlight on our skin. Note that after these treatments you have to fully lubricate and protect your skin to ensure that the pigmentation does not come back.

Prevention is better than cure. So invest in good SPF products and make sure you use them every day. Put reminders in your telephone if necessary. Enjoy the nice weather this week!
