Ascorbyl Palmitate is an oil-soluble vitamin C ester formed from ascorbic acid and palmitic acid. It is more stable than the water soluble vitamin C derivatives like Sodium Ascorbyl Phosphate and Magnesium Ascorbyl Phosphate. However, it is still prone to oxidation upon a contact with the oxygen atom in water.
Ascorbyl Palmitate May Intensify Skin Damage due to UV Radiation
The antioxidant and skin benefiting properties of Ascorbyl Palmitate in skincare and beauty products is questionable. A study published in the Journal of Investigative Dermatology revealed that Ascorbyl Palmitate may intensify skin damage due to UV radiation, particularly UVB radiation.
The Botanical Alternatives to Ascorbyl Palmitate
To protect skin against UV-induced free radical damage, choose plant oils like Rice Bran and Cacay oil.
Rice Bran oil is a good source of oryzanol, ferulic acid and tocopherols. These powerful antioxidants help protect skin against free radical and UV damage. Rice Bran oil has excellent anti-inflammatory and moisturising properties too. It is suitable for all skin types from mature, ageing to irritation-prone sensitive skin.
Cacay oil is the best source of Linoleic Acid (aka Omega 6 essential fatty acids). Cacay oil contains up to 85% Linoleic Acid. A study showed that Linoleic Acid helps protect skin against UV damage and premature signs of ageing.
Both Cacay and Rice Bran oil are the key important ingredients in Blue Chamomile & Cacay Facial Oil. For best protection against free radical, UV and other environmental skin damage, gently massage this facial oil all over the face and neck. Follow with your usual moisturiser.
Alternatively, you can mix a few drops of Blue Chamomile & Cacay Facial Oil with a small amount of serum or moisturiser, then apply it all over the face and neck.
Above all, it is important to apply a sun block whenever you plan to stay outdoor during the day. After serum, oil and or moisturiser (depending on the season and skin condition), I apply sunblock before I go out in the morning. A good sunblock helps prevent UV-induced skin damage including hyperpigmentation. At this moment, I am preparing to launch a zinc oxide-based sunblock. Watch this space!
