We know that vitamin C is the real secret to glowing, elastic and even skin, that AHAs have an almost magical power to reduce fine wrinkles and blemishes, and that retinol is the ingredient that’s the gymnastic ingredient for wrinkles. works like that. We know a lot about the cosmetic properties that are the source of beauty for the skin, but perhaps we are not aware that when mixed they can produce the opposite effect and not benefit us at all. Before applying an impossible combination to skin, experts help us identify the alchemy we should avoid, especially in summer, because the sun is one of the ingredients behind many reactions we don’t want.
perfume and incense
If you can’t do without your favorite scent, you may need to change habits, at least when you decide to tame the sun. Since, “perfume contains substances that react to sunlight and can cause irritation, spots and even minor irritation on more sensitive skin. These components are mainly alcohol and fixatives known as fragrances.” such as the essence of bergamot and musk, also known as musk”, explains Paula Jane, pharmacist and head of the Pedro Jane Group cosmetic unit, who recommends using perfumes before sun exposure “and if it is If unavoidable, clean the areas where it has been applied, such as the neck, wrist or décolleté, to avoid irritation or stains”.
makeup with sun
Makeup enhances us, accentuates facial features and brings more life and color, but in summer you have to take utmost care. Although the makeup we use has SPF, but when it is applied, usually the amount required for protection is not used. When out in the sun, experts agree: Neither perfume nor makeup. This is confirmed by Paz Torralba, director of The Beauty Concept Beauty Centers. “The sun doesn’t get in with chemical products at all, no matter how much natural makeup, blush or shadow we use,” he warns. So for the beach, always bet on naturalness, with safety.
Retinol and other acids
Retinol is a derivative of vitamin A, an ingredient present in many cosmetic formulations thanks to its powerful anti-aging effects and ability to accelerate cell renewal. “It improves expression lines, wrinkles and also lightens blemishes.” and leaves skin smoother and more radiant; but if it is combined with alpha hydroxy acids it can cause redness, irritation and even dryness and flaking”, details facialist Toralba. This is confirmed by pharmacist Paula Jane: “The exfoliating effect will be enhanced with combined application of other acids, the most commonly used in cosmetics are glycolic, lactic, malic, tartaric, citric, salicylic acids, which are also exfoliating and Hence they should not be applied together to avoid unnecessary irritation, sensitivity and flaking. All these components are excellent property on their own but are dangerous when combined”.
Regarding this explosive mixture, Montse Fernández, a dermatologist in the Pedro Jane group, assures that “under medical supervision, the action of retinol with glycolic acid may become a more potent cosmetic and the action of the two acids may have an additive effect.” But so will the potential for irritation. Hence, you have to be careful while using it, it should always be prescribed by a dermatologist and use of sunscreen in the morning is mandatory”.
Retinol and Benzoyl Peroxide
Vitamin C and Benzoyl Peroxide
Do not panic. You can use them together but their combined action reduces the effect of both the parts. This is what Paz Torralba suggests: “Benzoyl peroxide is an oxidizing agent that kills acne-causing bacteria. However, when it comes into contact with an ingredient such as vitamin C, which is harmless to oxidation, the two active substances form one. cancel the other and lose their potency and efficacy.”
Vitamin C and Alpha Hydroxy Acids (AHA)
Although they have remarkable benefits for the skin individually, they can have adverse effects in combination. “The antioxidant effects of these ingredients can cancel each other out. And you also have to be very careful because too much acid can cause irritation, flaking, and redness. It should be kept in mind that some acids can also destabilize vitamin C.” can”, argues Paz Torralba regarding these two active ingredients that do not have chemistry with each other.
Vitamin C and Niacinamide
Niacinamide is a form of vitamin B3 that is so essential for the proper functioning of our bodies, as explained by Pedro Jan Group dermatologist, “to smooth the skin, control pigmentation and also reduce acne scars.” Works for. Combination with vitamin C will not be photosensitizing, but since they are two very potent compounds, it is recommended to use them separately”.
AHA’s and AHA’s
AHA acid is a chemical exfoliator so combining the two products with AHAs can over-exfoliate the skin. So be warned from Korean cosmetics store NIIM. We recommend that you check that AHA acids feel great on your skin and, if you want to increase AHA levels in your routine, look for a product that has a higher percentage of glycolic, lactic, malic or citric acids. Ho. You can go through the level carefully and progressively. If you want to use two different products with AHAs, for example in a tonic and an essence, mix them in separate routines”, he elaborates. His recommendation is to use one product in the morning and the other in the evening.
Vitamin C and Sun
Surprise! Although it is popularly believed that they are incompatible, this is a good duet and is confirmed by the head of the Pedro Jane Group cosmetic unit: “Vitamin C is a fantastic antioxidant and depigmenting agent. It is the most widely used active ingredient to brighten skin and it is recommended to use products that include it in their formula for the day. Vitamin C is not incompatible with the sun, this is a false myth. We’ve heard that it can stain or irritate the skin, however, as long as it’s prepared and stabilized correctly, this won’t happen. The combination is often used with vitamin E and ferulic acid, which, in addition to enhancing the antioxidant effect, completely stabilizes these formulations for day use. They should be applied prior to sun protection required in any routine” sentence.
