GUIDE

Anti-aging skincare depends on skin type and tolerance. For resilient skin, BIOSAR's retinol options are the Serenity Age SPF day cream or the Serenvit retinol serum at night. Sensitive skin uses the bakuchiol night cream and the peptide eye contour serum, and dull skin adds morning antioxidants under SPF. Retinol is for resilient skin only, not during pregnancy or breastfeeding.

Anti-aging actives behave differently on dry, oily, and sensitive skin. The Serenity Age range plus five Serenvit serums lets you build a routine that fits your skin profile: retinol for resilient skin, peptides + bakuchiol for sensitive, vitamin C and resveratrol for dullness layered on top.

Why this guide

There is no universal anti-aging routine. The correct active depends on your tolerance, your concern, and your time of life. The breakdown below splits picks by skin type so you start with what your barrier can hold today, with room to graduate to higher-potency routines later. Every product is registered with the SFDA and was screened for compatibility with daily SPF.

  1. Step 1

    For resilient skin — retinol-led routine

    If your skin tolerates exfoliating acids and you have not been pregnant or breastfeeding for 12 months, retinol delivers the strongest evidence base on fine lines and tone. Use one retinol product at a time: the SPF day cream, which already contains retinol, or the retinol night serum, 2 evenings per week to start and increasing as tolerated, with SPF every morning. Alternate with peptides on quieter evenings.

    Anti-Aging Day Cream SPF30+, Retinol Serum: Contains retinol — not recommended during pregnancy or nursing.

  2. Step 2

    For sensitive skin — peptides + bakuchiol

    Sensitive skin reacts to retinol. The Serenity Age night cream uses bakuchiol (a plant-derived molecule with retinol-like behaviour and a calmer side-effect profile) and the eye contour serum uses peptides. Pregnancy-friendly, fragrance-light, evening or AM application.

  3. Step 3

    For dull or pigmented skin — antioxidants on top

    Daytime antioxidants block the oxidative cascade that drives fine lines and uneven tone. Resveratrol + ferulic acid in the morning, vitamin C complex on alternate AM applications, and the brightening day cream close the loop.

  4. Step 4

    Neck and décolleté — a separate priority

    Neck skin ages faster than the face but is rarely treated. The Serenity Age neck cream uses peptides + caffeine to address fine lines and crepiness specifically. Apply in upward strokes, morning and evening.

Frequently asked

When should I start using anti-aging products?

Daily broad-spectrum SPF and a basic antioxidant from your mid-twenties. Targeted retinol or bakuchiol routines from the early thirties or when fine lines first appear.

Is retinol safe during pregnancy?

No. Topical retinol falls into the avoid category in pregnancy and breastfeeding. Use bakuchiol or peptides instead, both featured in the Serenity Age night cream and the eye contour serum.

Can I use vitamin C and retinol together?

Yes, on different parts of the day. Apply vitamin C in the morning under SPF; reserve retinol for the evening. Daily layering on the same application is unnecessary and can irritate.

What changes with the neck cream?

Neck skin has fewer sebaceous glands and thinner dermis, so face creams underperform there. The Serenity Age neck cream is texturally heavier and uses peptides at a concentration tuned for the décolleté.
