What is retinal?
Retinal (retinaldehyde) is a more potent form of Vitamin A than retinol, but gentler than prescription tretinoin.

Who is this serum best for?
Mature clients ready for active anti-aging support. Best for those who have built tolerance to other retinoids.

How often should I use it?
Start 2–3 nights per week. Build to nightly use under esthetician guidance over 4–6 weeks.

Will I experience retinization?
Possible — mild dryness, peeling, or sensitivity in the first 2–4 weeks. Reduce frequency if persistent.

Can I pair with other actives?
Use on alternate evenings from AHAs or BHAs. Vitamin C in the morning pairs well.

Is it safe for sensitive skin?
Introduce gradually — start once a week if your skin is reactive.

Can I wear under makeup the next day?
Yes — morning skin should be fully absorbed.

Do I need sunscreen?
Absolutely non-negotiable — daily broad-spectrum SPF 30+ is essential with any retinoid.

Retinal Advanced is our go-to retinoid recommendation at Le Petit Spa Charlotte for committed anti-aging clients. Retinaldehyde (Retinal) sits between retinol and tretinoin in potency — it delivers more visible results than retinol with less irritation than prescription tretinoin. We recommend it for clients in their 40s, 50s, and beyond who are serious about smoothing fine lines, wrinkles, and signs of photoaging. Pairs beautifully with our anti-aging facials, microcurrent treatments, and chemical peel protocols.
