We are cosmetical, or at least we want to be. We want to know a lot and well what the products contain. It is no longer enough to know that a product is going to work, now we want to understand what is behind it, how it is made, and what its key components are.
The formulas are getting more complex, but there are four ingredients that can be considered the basis for achieving and maintaining a skin with a uniform, smooth and luminous appearance:
Vitamin C helps increase skin firmness and elasticity, as intervenes in the collagen formation, an essential substance to keep the dermis young and luminous. It is also recommended to treat photo-aged and blotchy skin.
Being a natural antioxidant has anti-inflammatory, anti-free radical, andVita hyperpigmentation and brightens the skin.
In topical application the concentration should be a minimum of 10-15%. Otherwise it would be insufficient. It is great in flash treatments. ANDs better use it with sun protection, above alli in its composition is ascorbic acid or ethylated ascorbic acid.
Everyone recommends it. What will it have. Retinol, also known as Vitamin A, is known as the star ingredient to delay skin aging. When applied to the skin it turns into retinoic acid, which increases and preserves collagen levels inside the skin for a plump, youthful complexion. Vitamin A too stimulates the skin cell regeneration cycle, reduces sebum production and prevents the formation of excess melanin to leave the skin smooth and uniform.
When administered at levels high enough to have a visible effect can cause irritation in the form of burning, redness and peeling. Ours are kind, but we recommend that your application is always done progressively and gradually, so that the skin gets used to this ingredient without reacting in an unfavorable way. Likewise, being photosensitive, it is very important that its application is always carried out at night.
Who does not like it. Hyaluronic acid is naturally present in all layers of the skin, where it has a protective effect and the function of retaining water to reconstitute tissues. As the human body ages, its content in the skin decreases. This contributes to the loss of freshness, hydration and elasticity of the skin, in addition to the loss of volume and firmness.
One of the main properties of hyaluronic acid is its ability to keep skin hydrated: It retains water in the epidermis, that is, it is as if it had a filling effect. This makes the skin smooth and gradually restores its elasticity, filling in small wrinkles and fine lines. Cosmetic products that contain hyaluronic acid they can also protect the skin against UV radiation, due to the antioxidant properties that prevent damage caused by the action of free radicals. Nor are often at risk of allergies.
The AHA or alpha-hydroxy acids they are water-soluble fruit acids. They represent an important group of natural, non-toxic acids from fruits and other vegetables.
To this group belong among others the glycolic acid, citric acid, or lactic acid. The salicylic acid is a beta hydroxy acid (BHA) fat-soluble, making it ideal for treatment of oily or acne-prone skin.
The Glycolic Acid removes spots caused by the sun, aging and severe acne. Reduces fine lines and restores fiber in acne-damaged skin tissues, healing and erasing wounds.
The lactic acid has a mildly keratolytic effect, that is, removes part of the dead cells from the horny layer, and that exfoliation helps the sebum to go freely to the outside and not to form pimples.
A major AHA concentration, the efficiency is higher, the maximum concentration allowed for sale being 10% of free acid. AHAs should be formulated at a pH greater than 3.5 and less than 4.2. If the pH is too high the tolerance will be better, but the efficiency will be lower. Hence the importance of getting cosmetic products with a balance between efficacy and tolerance.
Usually, just after the application of the acid, a slight tingling, which tends to decrease with continued use. Hence, it should be applied in a progressive.
Must be avoid its use on sensitive, intolerant skin or that present any pathology such as rosacea or atopic dermatitis. On the other hand, they are ideal in treating acne skin, with daily or weekly use depending on the concentration and pH.
It is preferable to apply them at night, without rubbing, avoiding the corners of the lips and the contour of the eyes. Even though they are not photosensitizing, it is important that during treatment with AHAs in the morning apply a sunscreen of at least SPF30, and that it is renewed throughout the day.
The AHAs used with retinoids and / or depigmentation is one of the most effective cosmetic combinations to transform the skin at night, along with the use of antioxidants and sunscreen in the morning. Hence it is considered a false myth that retinol cannot be used with AHAs.
