X-Strength Retinol Serum is a concentrated evening treatment that delivers visibly firmer, smoother, brighter-looking skin — all the results people reach for retinol for — without the flaking or tightness that usually comes with it. The texture is fast-absorbing and light, so it layers easily rather than sitting heavy on skin.

Apply a few drops to dry, cleansed skin in the evening, starting twice a week and building up to nightly use, then follow with a hydrating cream and SPF the next morning. A next-generation, HPR-type retinoid and blue-green algae do the heavy lifting, a peptide complex supports the look of firmness, and squalane, multi-molecular hyaluronic acid, provitamin B5 and allantoin keep the whole thing comfortable on skin.

Key Benefits

  • Next-Generation Retinoid Complex combines HPR-type retinoid and blue-green algae for a comfortable retinol-style routine.
  • Peptide P3 supports the look of skin firmness and elasticity.
  • Squalane & Multi-Molecular Hyaluronic Acid replenish moisture so the formula feels comfortable, not tight.
  • Provitamin B5 & Allantoin soothe skin as the actives work.
  • Fast-Absorbing, Lightweight Texture layers easily under cream.
  • Pairs With a Retinol Toner for a fuller renewal routine when skin is used to actives.

Start with two evenings a week on dry, cleansed skin, then gradually increase to nightly use as your skin adjusts.

Yes, but it's best to separate them — vitamin C or acids in the morning, this serum in the evening.

1. Apply a few drops of the serum to cleansed skin on the face, neck, and decollete in the evening. Do not apply to damp or steamed skin.

2. After the serum, apply HydraFusion Hydrating Gel Cream or SuperBiotic Regenerating Cream. In the morning, always follow with Sunscription SPF50.

3. If you are new to retinol, start with 2 times per week, gradually increasing frequency to daily use. If your skin is already accustomed to retinol, you can apply the serum every evening or alternate with Powerful RetinOil. For maximum results, use together with Advanced Retinol Toner — this ensures a complete cycle of renewal and intensive care.

4. For sensitive skin, do not combine with acids in the same routine to avoid irritation. If your skin is more resilient, you may combine the serum with acid-based products to enhance the effects of retinol. For non-sensitive skin, if the serum provides sufficient hydration, you may skip the cream in the evening and apply a restorative product in the morning instead. Retinol-based products are not recommended during pregnancy or breastfeeding. Please consult your doctor before use.
