Many consumers understandably choose to use titanium dioxide and zinc oxide as their preference for sunscreen filters.
Titanium dioxide or zinc oxide have been used for many years in combination with chemical sunscreens to enhance protection level in the longer UVA range (370 nm). Unlike chemical sunscreens, titanium dioxide and zinc oxide work by reflecting and diffusing UVR. Titanium dioxide and zinc oxide are hard to disperse and also leave the skin looking white on the skin, which is very undesirable. As a consequence of this the minerals were ground into a finer particle size and micronized.
Micronized Zinc Oxide and Titanium dioxide are the types used when the sunscreen does not leave the skin white and it is almost transparent. Micronized zinc and titanium undergo a chemical surface treatment to stop them clumping. What is not well known however is that the process of micronization leads to changes in the sun protective properties of titanium dioxide. The smallest particle shifts its protection from the longer UVA towards the UBV range.
Breaking out isn't something you should always experience but in some instances you will. Often with breakouts acne sufferers don't realise that lesions under the skin are pre existing. All acne starts with what is called a "micro-comedone" and they are invisible to the naked eye.
We are often asked why Skin Detox causes purging. I want you to think of it like constipation, as gross as it may sound. There is only one way for it to come out, it won't just disappear. We consider Skin Detox a laxative for the skin. The breakout doesn't usually last more than 4 weeks.
Vitamin A and Botanical Vitamin A alternatives cause an increase in exfoliation in the skin. Now if you have dead skin cells at the top of the pore and you suddenly increase exfoliation what happens is a breakout.
Some skins take time to adapt to the introduction of Vitamin A. The reaction you have is called a Retinoid reaction which may appear as:
- pink skin and slight flaking
- mild breakouts
- small red pimples that are itchy (worst case scenario)
Comedogenic products take time to cause breakouts. This is not purging, if you are using something comedogenic then the breakouts will continue. It can take 6 months after discontinuing a comedogenic product for the breakouts to clear.
Have you ever looked longingly into the fruit bowl and wondered what banana may do for the skin? Hey it's good enough to be ingested, why not slather it over my face?
Now we don't want to be the fun police, and it is not our intention to kill your creativity. We just love skin so much that we want you to look after yours and make educated decisions.
REMEMBER just because it's on the internet does not mean it is true. The internet and its counterparts are unregulated sources of information. Anyone can be an expert...and unfortunately there are many D.I.Y skincare recipes that are actually causing more harm than good.
Firstly D.I.Y is a one size approach. The person who came up with the concoction does not know your skin type and most likely does not have an understanding of how the skin works.
Secondly, food and cosmetic ingredients have different grades. Cosmetic grade ingredients are higher quality and have to meet a purity standard.
Thirdly, you need some form of preservative. Many D.I.Y masks contain raw eggs and raw honey which can lead to harmful bacteria.
There are many oils that contain over 25% oleic acid. These oils disrupt the skin barrier by causing moisture loss which results in flaking, an overproduction of skin cells. This may not be seen to the naked eye.
The moisture loss causes a temporary swelling of the surface which makes you feel like you are hydrated. Continued use will degrade the skin barrier. If you were to be measured with a technical device accurately measuring hydration, it would show the skin is losing moisture and the feeling is only superficial.
In an acne skin these oils will result in breakouts. If there are too many skin cells it will clog the follicle. Acne skin cells are different to a normal skin. Their skin comes off in sheets rather than grains of sand which blocks the follicles.
Common oils that contain over 25% oleic acid are Olive Oil, Macadamia Oil, Almond Oil, Apricot Oil, Avocado Oil, Marula Oil and Argan Oil.
There are 3 key ingredients that need to be in a cream to effectively repair the skin barrier. Ceramides, Cholesterol and Fatty Acids. Not only does it need all of these but they also need to be in the right proportions, being a 1:1:3 ratio.
So why does the skin of an eczema sufferer have so much trouble repairing itself?
Well it all comes down to genetics. Eczema sufferers have a mutation in the gene called Filaggrin. Filaggrin provides moisture and is an essential component of restoring the skin barrier. Eczema sufferers only have one copy of this gene, instead of two.
Dr Su (Royal Children’s Hospital – Melbourne) was involved with ground breaking research on eczema. Dr Su discovered that a defective skin barrier was the primary cause of eczema. Eczema sufferers have tiny cracks in the skin barrier that predisposes some people to eczema, allowing irritants to penetrate and set off an inflammatory cascade.
People prone to eczema have a much thinner skin barrier than people with normal skin and this can be seen under a microscope, even if they do not have obvious eczema lesions. This is why daily application of a moisturiser containing the 3 key ingredients is vital, because genetically eczema sufferers don’t have a normal skin.
Our Calm Protect Revive or Rescue Balm is the perfect cream for treating eczema.
Hyaluronic Acid keeps skin moist and elastic while hydrating the skin and smoothing out fine lines. It holds 1000 times it’s own weight in water. Hyaluronic Acid production in the skin reduces as we age, resulting in loss of elasticity which develops as wrinkles. It plays an important role in tissue regeneration and prevention of scarring.
Not all Hyaluronic Acid is created equally.
Peptides are short chains of amino acid sequences. They have the ability to trigger cellular processes that stimulate collagen production.
Peptides evolved from research into wound healing and studies on growth stimulation from human skin fibroblasts. Wound healing studies on human keratinocytes cultures showed a stimulatory effect from topical application of peptides.
There are four types of peptides.
1. Signal Peptides
2. Neurotransmitter-inhibitor Peptides
3. Enzyme Inhibitor Peptides
4. Carrier Peptides
Peptides have been proven to be more effective than the gold standard prescription Vitamin A in the treatment of photoageing.
