Skincare Science

𝔾𝕃𝕆𝕎𝕀𝕊𝕄 ☀️ | skincare coach on Instagram: "Science time! The skin consists of three main layers, including the outermost layer called epidermis. Epidermis has multiple layers itself: from the top stratum corneum to the bottom basal layer. If the ingredients of a cream or serum manage to make it somewhere in between these two, then that’s successful penetration. ⠀ There are a number of factors that can promote or inhibit ingredient penetration into the skin. ⠀ ➡️ A widely adopted rule says substance with a molecular weight or size less than 500 can penetrate the skin. To enter the cell, it must be even smaller, approximately around 400 in terms of molecular weight. Substances below 100 may enter the blood stream. The fact that a given molecule is incorporated into a formula with many other ingredients only complicates matters. For instance, an ingredient may bind to other ingredients in the formula making it larger. This is why conducting a clinical study and observing what changes occur in the skin gives a clearer picture of penetration. It is not possible to simply say that the molecular size of an ingredient will enable it or prevent it from penetrating the skin. ⠀ ➡️ There are other factors, not related to an ingredient’s size, that affect product penetration. Many people are uncertain as to why a toner containing alcohol or other solvents would be used in a skin care regime or as a skin-prepping agent, especially since solvents can be drying. The reason is that solvents change the solubility of the skin, allowing more water-soluble (hydrophilic and polar) ingredients like lactic acid to penetrate the skin. On top of that, most active ingredients are most effective at lower pHs. Our skin's barrier consists of oily stratum corner, which likes dissolving uncharged (free acid form), oily things, and don’t like dissolving charged, polar, watery things. So lower pH helps ingredients to To pass through the oily stratum corneum and into the skin to do their work. ⠀ Let me know if this is helpful!"

𝔾𝕃𝕆𝕎𝕀𝕊𝕄 ☀️ | skincare coach on Instagram: "Let’s learn about a powerful moisturizing ingredient - Squalane - today! My favorite night serum recently is Biossance squalane and lactic acid night serum, it contains plant based squalane and provides light exfoliation overnight. I only use it two or three times each week, but I always notice smoother and softer skin the second day when I wake up. ⠀ 👉Squalane vs Squalene Squalane oil is a saturated byproduct of squalene oil, a polyunsaturated hydrocarbon. Don’t be confused by “Squalane” and “Squalene” - Squalene (with an “e”) is a lipid produced naturally by our own skin cells, which is why its derivative, squalane (with an “a”), is such an excellent moisturizer for the hair, skin and nails; our bodies know what to do with it. ⠀ 👉Where is squalane sourced from Traditionally sourced from the livers of deep-sea sharks in the South Pacific, squalane oil has long been used in traditional medicine and is known as a “cure-all” across Asian cultures. It’s been used as a remedy for many different diseases, from constipation to cancer. Thanks to skin care professionals today, squalane is now harvested from many plant sources including olives, rice bran and sugarcane—providing an environmentally friendly and cruelty-free option. ⠀ 👉The benefits of squalane Squalane oil can mimic our natural sebum (oil), thus it’s very hydrating while keeping it lightweight and not clog pores. Along with its known moisturizing benefits, squalane oil helps fight bacteria on our skin. It could help relieve the symptoms and banish those blemishes. ⠀ ⠀ Do you like this ingredient?

𝔾𝕃𝕆𝕎𝕀𝕊𝕄 ☀️ | skincare coach on Instagram: "Drop a comment if you have any questions regarding acne! ⠀ Though people may have different skin types and conditions, breakouts are mainly triggered by the overproduction of oil and hormones. Basically, hormones ramp up your oil under the skin, which clogs your hair follicle, which leads to the growth of the zit-causing bacteria known as P. acnes. ⠀ Most mild acne can be treated with OTC (over the counter) treatments, including: ⠀ - Benzoyl peroxide. This ingredient kills the bacteria that cause acne, helps remove excess oil from the skin and removes dead skin cells, which can clog pores. OTC benzoyl peroxide products are available in strengths from 2.5 to 10 percent. Possible side effects include dry skin, scaling, redness, burning and stinging, especially if you have sensitive skin. ⠀ - Salicylic acid. This ingredient helps prevent pores from becoming clogged. OTC salicylic acid products are available in strengths from 0.5 to 5 percent. Possible side effects include mild stinging and skin irritation. ⠀ - Alpha hydroxy acids. Two types of alpha hydroxy acids that are used in nonprescription acne products are glycolic acid and lactic acid. Alpha hydroxy acids are synthetic versions of acids derived from sugar-containing fruits. They treat acne by helping to remove dead skin cells and reduce inflammation. Alpha hydroxy acids also stimulate the growth of new, smoother skin. This helps improve the appearance of acne scars and gives the impression of smaller pores. ⠀ Yet many skin disorders, including acne, can be a window into a systemic condition. For example, hair loss, excess hair growth, irregular menstrual cycles, or rapid weight gain or loss in addition to acne, or rapid onset of acne with no prior history of acne, can all be red flags of an underlying disease, such as polycystic ovarian syndrome, or other endocrine disorders. Talk with your doctor if you are experiencing additional symptoms; he or she may recommend further evaluation."
