makeup with sun

Makeup enhances us, accentuates facial features and brings more life and color, but in summer you have to take utmost care.

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

Benzoyl peroxide is an antibacterial active ingredient with anti-inflammatory action that is used in the treatment of acne “because it reduces the presence of bacteria that trigger this process”, explains dermatologist Jenn about this ingredient. that in itself can produce as a side effect some sensitivity of the skin, irritation and dehydration “Therefore when using this type of preparation it is recommended to use moisturizing agents, of which retinol is not found. is.” In terms of use, dermatologist Montsay Fernandez indicates that it has to be done at different times of the routine, “one in the morning and the other at night and always with sunscreen.”

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”.

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.
