Sunlight can promote reactions in many skincare chemicals. It can denature a compound into something inactive. Most of the skincare products in the market don’t show such directions as where to store and when to use them. Most of these chemicals act as exfoliators. As you all know, exfoliators remove dead skin cells, revealing the underlayer of the skin and promoting new cell growth. The layer of dead skin cells protects you from sunlight and newer cells are more prone to damage due to sunlight. Therefore, it’s necessary to exfoliate at night. Avoid them from direct sunlight whether they are part of a product or your natural DIY skincare.
Here are some chemical ingredients you should avoid exposing to sunlight.
1. Exfoliating Acids
Exfoliating acids like lactic acid naturally found in yoghurt, and glycolic acid naturally found in sugar and honey should be avoided from the sun. In addition to that some acids like mandelic acid, salicylic acid and azelaic acid which are part of many acne treatment products should also be prevented from sun exposure.
2. Retinol
Retinol is a part of many anti-wrinkle or anti-ageing products. It helps in cell renewal. Therefore, retinol is always recommended to use in a night-time skincare routine.
3. Citrus oils
Citrus oils are extracted from citrus fruits. They are used for healthy skin but can burn the skin when exposed to the sun.
4. Hydroquinone
It is a lightening agent which reduces melanin production in the skin. Less melanin means more sensitivity to the sun.
5. Antibiotic treatments
Antibiotic products are usually recommended for oily acne-prone skin to fight acne. Antibiotics like benzoyl peroxide and clindamycin dry out the skin and dried skin is more susceptible to sun damage.
