Arencia Retinal Booster Shot 30 ml

Retinal (retinaldehyde) and retinol are both vitamin A derivatives that the skin converts into retinoic acid. Retinal is one step closer in this pathway. Both retinal and retinol tend to be better tolerated than retinoic acid, which is found in prescription medicines. Individual reactions vary, though, so introduce retinal gradually too. Read more in our glossary entry on retinol.

Try the serum on a small area first. Then start with one or two evenings per week and gradually increase the frequency as tolerated. Some mild dryness or flaking may appear at first. If your skin starts burning, becomes significantly red or begins to peel, stop using newly introduced products and return to a simple, well-tolerated routine. Consult a dermatologist if symptoms persist.

According to the brand, the serum contains 200 ppm retinal, equivalent to 0.02%. Percentages referring to other ingredient complexes should not be confused with the concentration of retinal itself. The low concentration is one reason retailers also recommend it for starting out with retinoids. Tolerance varies, so introduce the serum gradually even at this concentration.

With retinoids, any change in skin texture and fine lines is generally assessed only after longer regular use. The brand does not provide results for this specific serum, and changes cannot be guaranteed within a specific timeframe: it depends on your skin's condition, how often you use it, SPF and how your skin responds to retinal.

Retinal is sensitive to light, so it belongs in your evening routine. Retinoids can also make your skin more sensitive to the sun, so use SPF 50 as the last step of your morning routine, even in winter and on cloudy days, and avoid intense sun exposure.

Not in the same evening routine. Don't use the serum on the same evening as Dr. Ceuracle Azelaic 10 & Madeca Ampoule, Sungboon Editor Green Tomato Pore Lifting Ampoule+ (which contains a PHA) or Sungboon Editor Kojic Acid Niacinamide Brightening Ampoule. Likewise, don't layer it with AHA/BHA/PHA acids, peels, strong vitamin C, benzoyl peroxide or another retinoid. Alternate these products on different evenings, or use them in the morning with SPF and retinal in the evening.

No. The serum contains retinal, a retinoid (vitamin A derivative), and retinoids are not recommended during pregnancy or breastfeeding. During this time, choose skincare without retinoids and discuss your choice with your doctor.

Both belong to an evening routine with a retinoid. PURITO Timeless Bloom Retinol Spot Cream is a retinol cream designed for targeted application to selected areas. Arencia Retinal Booster Shot is a retinal serum for the whole face, avoiding the eye area and lips, applied before moisturiser. If you want a retinoid only on specific areas, choose PURITO; for the whole face, choose Arencia. Don't use both retinoids on the same evening.

Skip the serum during pregnancy and breastfeeding, if your skin is very reactive, currently irritated or broken, and shortly before or after cosmetic procedures (peels, laser, waxing). It contains macadamia seed oil and rapeseed sterols. If you have a confirmed allergy to nuts or rapeseed, do not use it without prior advice from a qualified healthcare professional. If you have a diagnosed skin condition such as rosacea or eczema, discuss introducing a retinoid with your dermatologist. The brand does not state the origin of the cholesterol and ceramide, so we cannot recommend the serum as vegan.
