My Tri-defense Formula Against the Sun in my Skincare Routine

It’s a fact that the sun is the main cause of aging and skin discoloration. As much as it provides us with the beneficial vitamin D, it also is our skin’s worst enemy. So, protecting our skin against the damaging effects of the sun is imperative if you want to retain that youthful glow and age well.


I discovered this combination a year ago but I only started using the products this year. The philosophy behind this combination and layering is that they boost each other’s efficacy creating a somewhat tri-defense weapon. The routine is very simple. You layer the products right after you cleanse in the morning and after you applied your toner or essence.



The Tri-defense skincare routine:

Vitamin C

Vitamin C contains antioxidants and contributes to our skin’s collagen synthesis making this an important factor in skin health. Moreover, studies have shown that Vitamin C limits the damage induced by ultraviolet (UV) light exposure. Vitamin C is not a “sunscreen” because it does not absorb light in the UVA or UVB spectrum. Rather, the antioxidant activity of vitamin C protects against UV-induced damage caused by free radicals.


Furthermore, similar studies also showed that topical application of vitamin is more effective on photoprotection than oral supplements because the approach is more direct.


PURITO Pure Vitamin C Serum - My triple defense formula against the sun | Korean Skincare
PURITO Pure Vitamin C Serum. This vitamin c serum can sting a little bit because it uses pure ascorbic acid. So, if you are sensitive, this might not be good for you. This has also a weird smell that might affect your sensorial experience. INGREDIENTS: Sodium Hyaluronate (Hyaluronic acid, humectants), Ascorbic Acid (pure vitamin C), 1,2-Hexanediol (stabilizers), Niacinamide (brightening), Arginine (pH adjusters), Nelumbo Nucifera Flower Extract (fading-protecting agents), Magnolia Liliflora Bud Extract (humectants), Lilium Tigrinum Extract (humectants), Paeonia Lactiflora Root Extract (skin-conditioning agents), Tuber Magnatum Extract (skin-conditioning agents), Pyrus Malus (Apple) Fruit Extract (humectants), Panax Ginseng Root Extract (humectants), Tocopheryl Acetate(antioxidants), Brassica Oleracea Italica (Broccoli) Extract (cosmetic astringents), Ananas Sativua (Pineapple) Fruit Extract (skin-conditioning agents), Curcuma Longa (Tumeric) Root Extract (skin-conditioning agents), Sodium Polyacrylate (emollient), Adenosine(improves wrinkles), Disodium EDTA (stabilizers)


Amino Acids

Amino acids are organic compounds that combine to create proteins and they are naturally found in our skin. As we are taught in elementary science, amino acids and proteins are the building blocks of life. In topical applications of amino acids on the skin, different studies have shown that amino acids can increase collagen content of the skin.


Several amino acids used in the present study, such as EAA, BCAA, Gln, Glu, and Arg, have been reported to stimulate protein synthesis in several tissues in in vivo and in vitro studies.


Moreover, amino acids help promote skin immunity, maintain skin hydration, and resilience as it protects the skin from free-radicals that the sun and the environment may cause.

We should all know this by now how extremely important wearing sunscreen is. As the last step of our morning routine, sunscreen provides us the protection we need from the sun’s photo damaging effects. The filters present in a sunscreen can either block directly the UV rays as mineral sunscreens or absorb it and transform the UV into heat as in chemical sunscreens. No matter how effective the products that you use prior, but without spf it will be useless. So, as you finish layering the first two, complete the routine with a sunscreen.
